MAMAC Systems TE-703-D-7-A-1 Temperature Sensor

The 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 -40°F to 210°F. The 4-inch 304 stainless steel probe ensures rapid thermal conductivity and resistance to corrosion in hot water, chilled water, or low-pressure steam applications. Housed in a NEMA 4 (IP-65) powder-coated steel enclosure with welded seams and a gasketed cover, this unit is built for unconditioned environments where moisture, oil vapor, and contaminants are present. For secure pipe installation, it features a 1/8" NPT adapter, making it compatible with standard thermowells for high-accuracy sensing in building automation systems (BAS).

• High-Accuracy Sensing: Utilizes a 10K Ohm Type III NTC thermistor for precision interchangeability and signal stability.
• Rugged Enclosure: Industrial NEMA 4 / IP-65 painted steel housing protects internal electronics from harsh ambient conditions and moisture migration.
• Corrosion-Resistant Probe: The 4-inch 304 SS probe offers fast thermal response and durability in chemical-rich or high-humidity environments.
• Installation Ready: Integrated 1/8" NPT brass adapter streamlines mounting into existing thermowells for commercial HVAC piping systems.

Common Questions

What controllers are compatible with a 10K Type III thermistor?
The Type III curve is a standard in the industry, making this sensor natively compatible with Most BAS and DDC controllers including those from Schneider Electric, Andover, and many legacy systems.

Can this sensor be used in outdoor applications?
Yes, the NEMA 4 rated, powder-coated steel enclosure is specifically designed to handle unconditioned spaces and outdoor environments where protection against rain and hose-directed water is required.

Does this unit come with a thermowell?
This model includes the 1/8" NPT mounting adapter. While it is designed to seat against the bottom of a thermowell for accurate readings, the thermowell itself is typically sold separately or already installed in the piping.
