MAMAC Systems TE-703-D-7-A-1 Temperature Sensor 320788-704 If your resistance-to-temperature readings areThe MAMAC Systems TE 703 D 7 A 1 is a commercial grade immersion temperature sensor engineered for precise hydronic and HVAC monitoring. Designed with a 10,000 Ohm NTC thermistor (Type III), this sensor provides stable and repeatable resistance output across a wide temperature range of 40F to 210F. The 4 inch 304 stainless steel probe ensures rapid thermal conductivity and resistance to corrosion in hot water, chilled water, or low pressure steam
