The temperature transmitter BTT3224ALW is applicable to converting resistance of temperature or voltage of thermocouple sensor to standard current signal 4-20mA. The transmitter has two separate channels enabling measurement of difference temperature, average, average with redundancy, max. or min. temperature.Transmitter has compensation of ambient temperature influence and compensation of thermocouple cold junction using internal/external (Pt100) sensor or constant temperature. Most of parameters such as: sensor type, measuring range, current alarm signal when electric circuit is broken, output characteristic correction, user characteristic (60 points) are programmed using PC with Hart/USB/Bluetooth converter and BASI RAPORT 2 configuration software or KAP- 03 communicator. For request BASI can set temperature transmitter parameters like measuring range, type of sensor. The Transmitter BTT3224/ALW is designed for field use. BTT3224ALW can be used with temperature sensors mounted directly in transmitter’s casing or with external sensors connected with cable.their values are printed on label.
