SCC642 is a head-mounted temperature transmitter. It is used to convert a variety of RTD input signals into a scalable 4 to 20 mA analogue output signal. The transmitter 7 types of RTDs (Pt100, Pt500, Pt1000, Cu50, Cu100) resistance (0 up to 400?, 2000? or 10000?) and a wide range of linear voltage inputs (-10-75 mV, -100-100 mV, -100-500 mV, -100-2000 mV). SCC642 has an internal temperature sensor for active temperature compensation. This is a highly quality temperature transmitter, with an efficacy loss of less than 0.05% per year.
