User manual

The Multilogger System consists of a logger loftware application, a

USB-, LAN-,WIFI- or GPRS receiver module and one or more sensors

TSN-XX, PRO-XX, IP-XX, each including a transmitter system.

A USB- or LAN cable connects the receiver to the computersystem or

to the LAN network. The Logger application can synchronize the sen-

sor data from several receivers.

For the multilogger system many different sensors are already availa-

ble. The sensors can measure temperature -200 to +400°C (PT-100),

humidity, Voltage and CO2

The multilogger application at the computer displays all sensor data,

which have been transferred by temperature sensors to the receiver.

Temperature sensors continuously registrate temperature and report

new values to the USB-, LAN-, WIFI- or GPRS receiver at intervalls of

ca. 45 seconds.

Each sensor in the sensorlist reports the date and time stamp for the

most recent measurement data set. The right side window displays a

continuous curve for the registrated temperature for the selected

sensor.

Sensors and receiver use a wireless communication system, working

at 433MHz. This frequency is freely available for communication at

transmitting powers under 10 milliwatts.

Depending on surrounding building constructions, the allowed 10mW

power level allows a transmission range of 20-40 meters inside

buildings,theopeneldrangeismuchhigher.

Temperature sensors may be located inside or outside buildings, at any

place where a registrated overview of temperature curves is desired.

Unreliable signal levels may be improved substantially by slightly

modifying the sensor’s position or the receiver’s location.
