C 1 Universal Pressure Transmitter UniTrans Contents General Safety Instructions All pressure connections may only be opened after the system is without pressure! Warning Warning Observe the national regulations about safety and accident prevention , as well as the safety instructions in this operating manual when operating the pressure transmitter. Any operation not described in the following instructions must not be carried out.
C 2 Universal Pressure Transmitter UniTrans Product Description Product Description The UniTrans pressure transmitter can be used in level control applications as well as for pressure measurement applications in process industry. A variety of process connections, measurement ranges, main boards and display options result in a product for a wide range of applications. 2.1 Construction The UniTrans consists of a pressure sensor, a control interface unit and a housing cover with optional display.
C Universal Pressure Transmitter UniTrans Product Description 2.1.2 Processing Unit The processing unit, which is integrated in the housing contains the terminal compartment and the keypad used for programming the transmitter. The four keys must be activated (unlocked) before use. During normal operation the keypad is locked to protect data and functions previously entered. The keypad is automatically locked when no key is hit for 10 minutes.
C Universal Pressure Transmitter UniTrans Product Description Transmitters with displays offer a larger number of programming and processing options. These options include alarm status, damping, signal inversion, tank linearization and diagnostic messages. Display units can be easily upgraded (see chapter 4.2). 2.2 Function The mode of operation for signal conversion works in the same way for all versions. The pressure transducer converts the existing pressure into an electrical signal.
C 2.3 Universal Pressure Transmitter UniTrans Product Description Installation Examples The UniTrans is primarily used to monitor the pressure in pipes, technical equipment and tanks. Depending on the pressure range pressures between 20 mbar up to 1000 bar can be measured. The pressure is measured using absolute (against a vacuum) or relative (against external or air pressure) measurement depending on the type of sensor selected.
C Universal Pressure Transmitter UniTrans Product Description Level Control: Level Control: Externally mounted Combined pressure and head pressure (with front flat diaphragm) are measured by two externally mounted pressure transducers. The two signals are analyzed and the differential is calculated by a PLC or suitable signal con- Published 16.2.04 verter. Subject to change due to technical modifications.

C 4 Universal Pressure Transmitter UniTrans Installation Installation The device should be installed/operated in accordance with the regulations of ElexV, the Device Safety Regulation, this operating manual and generally recognized industry standards. 4.1 Pressure Transmitter Installation The pressure transmitter’s diaphram should not come into contact with hard or sharp objects.
C Universal Pressure Transmitter UniTrans Installation Connection Cable Supporting String • All functions are programmable once the pressure transmitter has been upgraded with a display unit. The adjusted parameters are stored after the display unit is removed. The display unit can be rotated in 300°, so that it can be read under various installation conditions. The housing cover with built-in display can be fastened to the housing at all four side positions. 4.
C 4.4 Universal Pressure Transmitter UniTrans Installation Electrical Connection Please observe local installation regulations (Germany: VDE-Standard). The terminal voltage should not exceed 36 V. Attention The supply voltage is between 12 and 36 V DC. The power supply and the output signal are transmitted via a two-wire cable (max. 12 mm outer diameter, max. 14 AWG) and connected in accordance with the pin configuration.
C Universal Pressure Transmitter UniTrans Installation Terminal Configuration Ground L- supply minus (to connect the negative signal line) L+ supply plus (to connect the positive signal line) I Test circuit; connect the ampere meter between terminals L+ and I The unit must be properly grounded in order to guarantee EMC resistance. 4.5 Pressure Compensation when using a Relative Pressure Sensor A Goretex diaphram is used to compensate for the atmospheric pressure under the IP 65 Protection Method.
C Universal Pressure Transmitter UniTrans Operation of Transmitters without Display 5 Operation of Transmitters without Display 5.1 Preparation This unit can be programmed before or after installation. • Connect an ampere meter to the device’s output (between terminals I and L+). • Note that after each action, a brief oscillation/deflection of 20 mA occurs (verification of a successful action).
C 5.3 Universal Pressure Transmitter UniTrans Operation of Transmitters without Display Calibration with Pressure 5.3.1 Zero Point Calibration Make sure that the pressure to be used as the zero point (P 0 %), is present at the transmitterer diaphragm before calibration. Calibration Value (2 sec.) (2 sec.) Confirm Function (2 sec.) meas Zero point calibration 024-DS-GB 5.3.2 Span Calibration Calibration of the measurement range (span).
C 5.4 Universal Pressure Transmitter UniTrans Operation of Transmitters without Display Calibration without Pressure Determine the current reference values for the zero point and the span to be entered in the transmitter before calibration. This is done as follows: 5.4.1 Zero Point Calibration • Determine the hydrostatic pressure of the liquid’s surface that meets the zero point. • Adjust this pressure in proportion to the sensor’s nominal pressure range.
C Universal Pressure Transmitter UniTrans Operation of Transmitters without Display Example: A pressure transmitter with 0 ... 400 mbar (nominal pressure) is to be programmed. The liquid’s surface (with a density of 1) is 1 m above the diaphragm at the zero point. The maximum (span end-point) should be 3 m. The measuring range (span) is 200 mbar.
C 5.5 Universal Pressure Transmitter UniTrans Operation of Transmitters without Display Integration Time (Damping) Adjustment The following integration time settings can be used: 0, 1, 5, 20 and 40 s. The sensor’s measured values can then be averaged using the adjusted integration time. Calibration Value (2 sec.) Calibration Value (2 sec.) (2 sec.) 4 times Calibration of the integration time 5.
