The HART universal


SITRANS TR300 with HART- protocol is designed to support all commons, thermocouples, resistance and Millivolt sensors. Setup is quick and easy with SIMATIC PDM or handheld communicator. Unique user-friendly details are implemented: Without opening the 4-20mA loop the output current can be read out directly with a multimeter. A red/green LED shows the technician the status at a glance.
