2 Introduction 2.1 Appropriate use The IMPAC ISR 320 pyrometer is a stationary, digital pyrometer for non-contact temperature measurement on metals, ceramics, graphite, semiconductors etc. in the range between 700 and 1700 °C. The pyrometer measures in 2-color mode (ratio principle) in which two adjacent wavelengths are used to calculate the temperature.
Optics Sighting: Optics: Distance Ratio: Built-in LED targeting light and LEDs for intensity alignment Fixed optics a=300 mm or a=800 mm approx. 100 : 1 Environment Protection Class: Operating Position: Ambient Temperature: Storage Temperature: Relative Humidity: Weight: Housing: CE-Label: IP 65 IEC 60529 (value in mated condition) Any 0 to 70 °C at housing -20 to 80 °C Non condensating conditions 0.
2.4 Dimensions All dimensions in mm 2.5 2.6 Physical User Interface 1 8-Pin Connector 2 Signal light for power supply 3 Intensity change indicators Accessories (optional) Numerous accessories guarantee easy installation of the pyrometer. The following overview shows a selection of suitable accessories. You can find the entire accessory program with all reference numbers in Chapter 8, Reference numbers. 2.6.
2.6.3 Air Purge The air purge protects the lens from contamination of dust and moisture. It has to be supplied with dry and oil-free pressurized air and generates an air stream shaped like a cone. 2.6.4 90° Mirror The 90° mirror enables the capture of objects at an angle of 90° to the pyrometer axis. 2.6.5 Scanning Mirror The scanning mirror unit SCA 300 allows the measured object to be scanned over a certain range.
3 Controls and Installation 3.1 Electrical Installation The pyrometer is powered by 24 V DC ± 25% (very well stabilized, ripple max. 50 mV). It is important to ensure correct polarity when connecting the device to the power supply. To meet the electromagnetic requirements (EMV), a shielded connecting cable must be used. LumaSense offers connecting cables, which are not part of the standard scope of delivery. The shield of the connecting cable has to be connected only on the pyrometer’s side.
3.1.2 Connecting the pyrometer to a PC The pyrometer is equipped with an RS485 serial interface. With the RS485, long transmission distances can be realized and the transmission is, to a large extent, free of problems. The RS485 also allows several pyrometers to be connected in a bus system. If an RS485 connection is not available at the PC, it can be accomplished using the RS485 to USB connector.
can also be connected with its serial interface, whereas the digital display DA 6000-N has to be connected with its serial interface). Connection of additional units Other instruments like an analog controller or printer can be connected to the display in a series as shown above (total load of resistance max. 500 Ohm). 3.2 3.2.1 Sighting LED Targeting Light The ISR 320 is equipped with a LED targeting light to assist with aligning the pyrometer to the measuring object.
3.3 3.3.1 Optics Spot Sizes The ISR 320 has fixed optics for 300 mm or 800 mm measuring distance. The table of spot sizes in relation to measuring distance shows examples of the pyrometer’s spot size M [mm] in relation to the measuring distance a [mm] (min. 90% of the radiation intensity). Increasing or decreasing the measuring distance will change the spot size. . Note: In the 1-color (mono) mode, the pyrometer can measure objects at any distance (whether focused or non-focused).
4 Settings / parameter descriptions The pyrometer is equipped with a wide range of settings for optimal adaptation to the required measuring condition and to measure the temperature correctly. The digital PC interface allows you to exchange data with a PC either by using the supplied InfraWin software or by using the Universal Pyrometer Protocol (UPP) commands with your own communication program (see Chapter 7 for the UPP Data Format commands).
Note: Emissivity Slope K Settings: 0.800 to 1.250 in steps of 1/1000 (2-color mode). 4.2.1 Temperature Errors Cause by Non-Graybodies A graybody target has emissivity that is the same at each of the two wavelengths used for measurements and is constant throughout the temperature range. The ratio of the emissivities, 1 / 2= 1 and stays constant regardless of the target temperature. When a target deviates from this, that is when 1 / 2 does not equal 1.0 and a slope adjustment is required.
4.3 Transmittance Transmittance is a parameter that can compensate for signal loss due to external windows etc. For example, if the emissivity of the material is 0.6 and the transmittance of an additional window is 0.9, then the product would be 0.54 which is well inside the allowed range. The product of transmittance and emissivity ( x ) must not be less than 10% Note: Transmittance Settings: 10% to 100% in steps of 1/1000 (1-color mode). 4.
Double Storage Mode: Double storage mode comes into effect when selecting one of the reset intervals. This mode utilizes two memories. With the first memory, the highest measured value is held and is deleted alternately in the time interval set (clear time). The other memory retains the maximum value throughout the next time interval. The disadvantages of fluctuations in the display with the clock frequency are thereby eliminated.
4.7 Relative Signal Strength Relative signal strength stands for the product of emissivity, surface coverage, and transmission of the material between object and pyrometer. 4.8 “Dirty Window” Warning The ISR 320 pyrometers are equipped with a warning level “dirty window” monitoring system. A correct temperature measurement might be impossible if the ratio pyrometer is working at a too low signal level.
4.11 Sub Range You have the opportunity to choose a sub range (minimum span 50 °C) within the basic measuring range of the pyrometer. This sub range corresponds to the analog output. Example: Range 700…1700 °C, Sub Range 925…975 °C. The sub range setting also affects the maximum value storage when the Clear Peak Memory tclear is set to AUTO. For more information on the tclear AUTO setting, refer to section 4.5.
Close below: The contact closes (switches to ground), if the temperature falls below the entered value in the “SP1“ box. If the temperature exceeds that value plus the hysteresis the contact opens (a hysteresis between 2 and 20°C can be set to avoid oscillating of the switch in the switch point). When the ISR 320 is used in ratio mode, the limit switch can be used for the “dirty window” function, the switch off, or the switch contact.

5 Software InfraWin The operating and analyzing InfraWin software is included with delivery of the pyrometer. In addition to allowing you to make parameter adjustments, the InfraWin software also provides temperature indication, data logging, and measurement analysis features. This section gives an overview about the functions of the software. It also provides a description of the individual icons found in the program's help menu.
5.4 Basic settings All preset values for the device can be displayed and modified, if necessary under the Devices/Parameters window. Changing an existing pyrometer setting can be accomplished by typing a value in an input box or by selecting a preset value from the list field. Choose the correct settings for your application from the displayed options. This window contains the parameter settings described in Chapter 4, Parameters. 5.4.1 Open/Save 5.4.
In the lower part of the window, the connection with the preset baud rate can be checked. Here the command was sent 100 times with 19200 baud. It has taken 0.800 seconds without transmission errors. Emi: AutoFind: If the true temperature of the measured object is known, you can calculate the emissivity of the measured object using the Emi: AutoFind function: A measured temperature is displayed with the current set emissivity (in this example 100%) (here: 725.5 °C).
5.6 Warning Level / Switch-Off Level In addition to the relative signal bar graph, the warning level and the switch-off level are indicated as vertical lines in colors corresponding to the windows below. The ISR 320 pyrometers are equipped with a warning level “dirty window” monitoring system. A correct temperature measurement might be impossible if the ratio pyrometer is working at a too low signal level.
Once the temperature entry has been entered and confirmed with OK, InfraWin will then calculate the emissivity slope. The new emissivity slope will immediately appear along with the new temperature, which can be used for further temperature measurement. 5.8 Measurement online trend The measurement function allows you to access a number of input tabs located on the left side of the screen. The main or home tab is the Output Screen. You can toggle the input tabs on and off by clicking them.
frequency that readings were taken (settings at 5.9 PC sampling rates). As the amount of data increases, so does the amount of storage space required to save it. In order to save room, all .i12 data files are stored by a binary code. 5.10 Output .TXT file (analyzing) The same file as under Output listing may be converted into a text file and can be easily opened, for example with Microsoft Excel.
After entering the aperture and the main spot size, the input of interim values calculates spot sizes in different measuring distances of the fixed optics. 5.14 Search I/O Module The I/O Module allows accessories to connect to the software and is used to trigger measurement externally or to send a signal (like a relay) under certain conditions.

6 Maintenance 6.1 Cleaning ISR 320 window Because there are no moving parts in the ISR 320, the only regular maintenance required is a periodic inspection of the front window for build-up of foreign particles which, in time, can influence the energy received by the instrument. The ISR 320 has a “Dirty Window” warning alarm feature that can measure the current window/optical path transmission and provide a contact closure alert when the window transmission falls below the user set point.
In the 1-color (mono) mode, the pyrometer can measure objects at any distance. However, the object has to be bigger than or at least as big as the spot size of the pyrometer in the measuring distance. In the 2-color (ratio) mode, the object can be somewhat smaller than the spot diameter. Additional information on this topic can be found in Section 3.3 Optics. Obscured window: Clean the window. Refer to Section 6.1.
7 Data format UPP (Universal Pyrometer Protocol) Software commands can be exchanged directly with the pyrometer through an interface using suitable communication software or by using the Test function located in the Pyrometer Parameters window of the InfraWin software package.

9 Troubleshooting Symptom Probable Cause Comments No analog output even if the display shows a temperature above lower range limit Reversed leads to ISR 320. The ISR 320 is diode protected if power leads are reversed. Reversed leads to other instruments in the current loop. See section 3.1 Open circuit in lines connecting all instruments in current loop. Total burden higher than 500 Ohms Insufficient supply voltage (See wiring diagram). Temperature readings are too low Target size too small.
Symptom Probable Cause Comments Incorrect slope adjustments. See sections 4.2, 5 The measurement is influenced by reflections of hot machine parts Use mechanical accessories to avoid the influence of the interfering radiation. If target emissivity is less than 1, reflections from nearby hot objects will influence readings. Block reflection paths to see if readings drop to expected temperature. Incorrect spectral response for application. ISR 320 may be “seeing” through target.
Symptom Probable Cause Noisy readings (fast fluctuations). Improper grounding of cable shield and/or ISR 320 housing. Comments Flame or reflections of flame may be entering the field of view. Extremely dense steam, smoke, thick dust, personnel or moving machinery intermittently blocking 95% of optical path of ISR 320. ISR 320 Manual Non-uniform emissivity of large moving targets. Slower response speed is required. Faulty ISR 320. Contact LumaSense. See section 1.
