The HART universal


SITRANS TH300 with HART- protocol is designed to support all common 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 read out directly with a multimeter. A red/green LED shows the technician the status at a glance.
