Application and function

The temperature transmitter AT-3 is applicable to converting resistance of temperature sensor Pt100 to standard current signal 4…20mA. Transmitter has function of compensation non linearity of the sensor. Transmitter can be built in head of sensor. Electrical connection is made with cable cross section up to 1,75 mm2. Transmitter can be ordered with factory set configuration according to customer request. User has also possibility of changing configuration using PC computer with converter USB-AT-3 and special software. In addition to change measuring range user has possibility of configuration behavior of transmitter when sensor is broken and setting compensation of resistance in 2 wire sensor.
