SEM310

Complete with HART Protocol, the SEM310 universal temperature transmitter accepts Pt100, thermocouple, mV and slidewire sensors and can be integrated into systems where the HART protocol is required. The HART communication protocol allows the user to quickly and easily download information or interrogate the device. It is small in size yet has a performance superior to other larger and more expensive transmitters. A sensor referencing facility enables the transmitter to be accurately matched to a particular sensor.
