Head Mounted Transmitters convert low-level input signals from field sensors into a proportional 4 - 20 mA output that is ideal for driving other control instrumentation.
Few models of Radix temperature transmitters also has signal isolation and also comes with the HART communication options. Radix temperature transmitters convert a variety of input signals into a scalable 4 to 20 mA analogue output signal. The transmitter converts 8 types of thermocouples (B, E, J, K, N, R, S, T), RTDs (Pt100, Pt500, Pt1000, Cu53, Ni100, Ni500, Ni1000) resistance (0 up to 400Ω, 2000Ω or 5000Ω) and a wide range of linear voltage inputs (-10-75 mV, -100-100 mV, -100-500 mV, -100-1000 mV). Few head mount temperature transmitter has an internal temperature sensor for active temperature compensation. The SCC641/631 is in range high quality temperature transmitter, with an efficacy loss of less than 0.05% per year.
