Temperature Transmitter  

SITRANS TR300 with HART- protocol is designed to support all common thermocouples, resistance and millivolt sensors. Setup is quick and easy with SIMATIC PDM or a handheld communicator. Unique user-friendly details are implemented, one of them being the direct readout of the output current with a multimeter without having to open the 4 … 20 mA loop. A red/green LED indicates the device status at a glance.
