MAMAC Systems TE-702-B-7-B Temperature Sensor

The MAMAC Systems TE-702-B-7-B is a heavy-duty duct temperature sensor engineered for precise thermal monitoring in high-velocity HVAC environments. Featuring a 10,000 Ohm NTC Thermistor (Type III), this unit delivers highly accurate resistance-to-temperature curves essential for advanced building automation systems. The 6-inch 304 stainless steel probe is designed to minimize thermal logging and maximize response times within the airstream. Built for longevity in commercial mechanical rooms, the sensor is housed in a NEMA 1 galvanized steel enclosure, providing superior protection against physical damage and EMI interference. This 10k Type 3 thermistor is compatible with most major BAS controllers, making it a reliable choice for duct mount temperature sensing during retrofits or new installations. Its rugged construction ensures stable resistance values across a wide operating range, reducing technical call-backs and ensuring consistent system performance.

Key Benefits for Technicians:

• High-Accuracy 10k Type III Thermistor: Ensures precise signal feedback for critical PID control loops in air handling units.
• Rugged NEMA 1 Enclosure: The powder-coated galvanized steel housing stands up to vibration and harsh mechanical room conditions.
• Versatile 6-inch Probe Length: Ideal for mid-stream mounting in standard commercial ductwork to ensure representative air sampling.
• Simplified Installation: Features integrated mounting flanges and standard wiring terminations for rapid field deployment.
• Corrosion-Resistant Hardware: The 304 stainless steel probe prevents oxidation, maintaining sensor integrity over time.

Common Questions Regarding the TE-702-B-7-B:

Is the 10k Type III thermistor compatible with my existing controller?
The Type III thermistor provides a specific resistance curve (10,000 Ohms at 77°F) that is native to many industry-standard building management systems; always verify the input resistance requirements of your specific DDC hardware.

Can this sensor be used in high-moisture or outdoor applications?
This specific model features a NEMA 1 enclosure intended for indoor duct applications. For high-humidity or wash-down environments, a NEMA 4 or weather-resistant enclosure would be required.

What is the primary advantage of the galvanized steel junction box?
Unlike plastic alternatives, the galvanized steel housing protects the internal wiring connections from physical impact and provides a more secure anchor point for conduit fittings.
