High precision temperature transmitters for head mounting, T120 and T121, are designed for universal application on machines, plants, installations and in process industry. They convert the input signals and retransmit them into a normalized signal in current through a 4-20 milliAmpère loop. Input signals can come from 2, 3, 4-wire RTD sensors such as Pt100 (EN 60751) and Ni100 (DIN 43760). The T121 model also acquires Pt500, Pt1000, and thermocouple signals from J, K, R, S, T, B, E, N type (EN 60584), voltage and resistance. T120 and T121 are characterized by compact size and spring clamps connections. All available operating parameters are configurable by EASY SETUP / EASY LP software.
