esCrIpTIon of peraTIon esCrIpTIon of peraTIon Temperature Sensors The MicroTech III controller uses passive negative temperature coefficient (NTC) 10K ohm sensors. These sensors vary their input resistance to the MCB as the temperature changes . Table 3 details the resistance versus temperature values . For typical sensor wiring examples refer to Figures 12, 13, and 14 .
