MAMAC Systems TE-702-B-12-A Temperature Sensor

The MAMAC Systems TE-702-B-12-A is a precision duct temperature sensor engineered for demanding commercial HVAC applications. This unit features a 10,000 Ohm NTC Thermistor (Type II), ensuring high stability and accurate resistance-to-temperature conversion for precise environmental control. Built with a 12-inch 304 stainless steel probe, it provides excellent thermal conductivity and durability in high-velocity airflow environments. The sensor is housed in a heavy-duty NEMA 1 galvanized steel enclosure, protecting the internal thermistor element from physical impact and moisture. Designed for seamless BAS integration, this sensor is compatible with most building automation systems and controllers that utilize 10K Type II curves. The duct mount sensor configuration and rugged construction make it a standard choice for contractors looking for reliable HVAC temperature monitoring in air handling units and return air ducts. Its robust design minimizes signal drift, ensuring long-term repeatability without constant recalibration.

• 10K Ohm Type II Thermistor: Provides a standard resistance curve compatible with various DDC controllers.
• 12-Inch Stainless Steel Probe: Offers extended reach for accurate core-stream air temperature measurements in larger ducts.
• NEMA 1 Enclosure: Durable galvanized steel housing ensures protection for the electrical terminations and sensor leads.
• Wide Operating Range: Engineered to maintain accuracy across broad temperature spans typical of northern climate HVAC systems.
• Interchangeability: High-precision manufacturing ensures sensor interchangeability without requiring system-wide adjustments.

How do I verify the resistance values for troubleshooting?
Using a calibrated multimeter, measure the resistance across the sensor leads and compare the value against a standard 10K Type II resistance chart relevant to your ambient temperature reading.

Can this sensor be used in high-moisture air streams?
While the stainless steel probe is corrosion-resistant, the NEMA 1 enclosure is intended for indoor applications. For high-humidity or outdoor environments, ensure the enclosure remains dry and protected from direct water ingress.

Is the probe length suitable for small residential ductwork?
The 12-inch probe is optimized for commercial-grade air handlers and large ducting. For smaller residential vent applications, a shorter probe length might be required to avoid physical interference.
