Head Mount Temperature Transmitter with HART Communication


SCC631 is a head-mounted temperature transmitter with universal input and an isolated 2-wire, 4~20 mA output with HART. HART technology superimposes digital communication on top of the 4-20 mA signal for two-way field communication and enables additional information beyond the normal process variable to be communicated to and from the field instrument. SCC631 ships with customer specific measurement range settings, requires no external power supply when configured by USB interface and is programmed via simple and user friendly software. This HART transmitter is used to convert a variety of input signals into a scalable 4 to 20 mA analog 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). The HART transmitter SCC631 has active temperature compensation. SCC631 provides galvanic signal isolation of 2000 V AC RMS, 50/60 hz / 1 minute between the input and the 4~20 mA output.
