MAMAC Systems TE-702-C-17-D Temperature Sensor

The MAMAC Systems TE-702-C-17-D is a rugged duct temperature sensor engineered for precise thermal monitoring in demanding HVAC and building automation environments. This model features a high-accuracy 20,000 Ohm NTC thermistor, which provides stable resistance-based output for reliable data transmission to your controller. The 12-inch 304 stainless steel probe is designed to reach the center of large ductwork to capture accurate representative air temperatures, avoiding the inaccuracies associated with stratified airflow. Housed in a NEMA 4 painted steel enclosure, this sensor is built to withstand unconditioned spaces where moisture, oil vapor, and dust are present. The powder-coated 18-gauge cold-rolled steel construction ensures the internal sensing element remains protected against mechanical shock and environmental contaminants, maintaining long-term system calibration. Ideal for commercial HVAC systems and industrial air handlers, the TE-702-C-17-D integrates seamlessly with most standard BAS platforms that support 20k ohm thermistor curves.

• Enhanced Accuracy: Features a high-precision 20k ohm NTC thermistor with a +/- 0.2°C interchangeability at 77°F for tight environmental control.
• Industrial-Grade Build: The NEMA 4 rated enclosure and welded seams offer superior protection against condensation and hose-directed water.
• Extended Reach: A 12" stainless steel probe allows for deep insertion into large plenums to measure the average air temperature effectively.
• Versatile Compatibility: Designed for seamless integration with a wide variety of HVAC controllers and building management systems.
• Resilient Materials: Utilizes 304 stainless steel for the probe and powder-coated steel for the housing to prevent corrosion in harsh duct environments.

Is this sensor compatible with my specific HVAC controller?

The TE-702-C-17-D utilizes a 20,000 Ohm NTC thermistor. You must verify that your controller's input configuration supports the 20k ohm resistance curve to ensure accurate temperature translation.

Can I install this sensor in an outdoor duct?

Yes, the NEMA 4 / IP-65 rated enclosure is specifically designed for unconditioned or outdoor environments, providing protection against wind-blown dust, rain, and moisture ice formation.

How do I mount the sensor to the ductwork?

The unit features an external mounting bracket. Technicians should drill a 3/8-inch hole, insert the 12" probe, and secure the housing using two #8 self-tapping sheet metal screws.
