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

The MAMAC Systems TE-702-B-7-D is a rugged duct temperature sensor engineered for precision monitoring within building automation systems (BAS) and commercial HVAC environments. Featuring a high-accuracy 10,000 Ohm NTC Thermistor (Type III), this sensor provides stable and repeatable resistance output, making it compatible with a wide range of controllers from major manufacturers. The 12-inch probe is constructed from 304 stainless steel and is hermetically sealed to prevent moisture migration and contamination, ensuring long-term reliability in high-velocity air streams.

Designed for the field technician, the TE-702-B-7-D includes a NEMA 1 galvanized steel enclosure with a 1/2-inch conduit knockout for streamlined wiring. The keyed enclosure cover allows for quick access during commissioning without the need to fully remove mounting screws, and the external mounting bracket ensures a secure fit even on irregular duct surfaces. This HVAC temperature sensor is ideal for monitoring supply, return, or discharge air in air handling units (AHUs) and VAV systems where fast thermal response and environmental durability are critical.

• High-Accuracy Sensing: Utilizes a 10k Type III thermistor for precise temperature feedback across standard commercial ranges.
• Durable Construction: The 12" stainless steel probe is crimp-attached to the galvanized steel enclosure for superior mechanical strength.
• Efficient Installation: Features a low-profile flange and a keyed cover design that simplifies field wiring and reduces labor time.
• Universal Compatibility: Standard resistance output integrates seamlessly with most HVAC control systems and building management controllers.

Is this sensor compatible with my existing BAS controller?
The Type III 10k Ohm NTC curve is an industry standard. If your controller is configured for a 10k Type 3 thermistor, this unit will provide accurate data without further calibration.

Can this be mounted on round or uneven ductwork?
Yes, the integrated external mounting bracket is designed to conform to flat or irregular surfaces, ensuring a flush and stable seal against the duct wall.

Does the probe require a thermowell for duct applications?
No, this unit is designed for direct insertion into air streams. The stainless steel sheath provides necessary protection against airflow and light debris.
