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

The MAMAC Systems TE-702-B-12-B is a professional-grade duct temperature sensor engineered for precise thermal monitoring in commercial HVAC and building automation systems. Designed with a 10k Ohm NTC Type II thermistor, this sensor provides high-stability resistance output for accurate air temperature measurement across a range of -40°F to 210°F. The 6-inch 304 stainless steel probe is hermetically sealed to prevent moisture migration, ensuring the integrity of the sensing element even in high-humidity airflow environments.

Housed in a rugged 18-gauge NEMA 1 galvanized steel enclosure, this unit is built for durability in mechanical rooms and air handling units. The TE-702-B-12-B features a keyed enclosure cover that allows for easy wiring access without fully removing the screws, and includes a 1/2-inch conduit opening for secure electrical connections. Its Type II thermistor curve is compatible with a wide array of industry-standard DDC controllers, making it a reliable choice for field replacements or new installations in supply, return, or mixed air ducts.

• System Compatibility: Features a standard 10,000 Ohm Type II thermistor element compatible with most BAS and HVAC controllers.
• Industrial Durability: The NEMA 1 enclosure and 304 stainless steel probe withstand mechanical shock and vibration in commercial ductwork.
• Precise Response: The 1/4-inch O.D. probe is crimp-attached to the enclosure for low-profile mounting and rapid thermal transfer.
• Simple Integration: Standard 1/2" conduit connection and keyed cover facilitate efficient field wiring for contractors.

What is the sensor accuracy for the TE-702-B-12-B?
The 10k Type II thermistor provides an interchangeability accuracy of +/- 0.36°F (+/- 0.2°C) at 77°F, ensuring high-precision data for climate control logic.

Can this sensor be used in outdoor air ducts?
While the NEMA 1 enclosure is designed for indoor use, the 304 stainless steel probe is hermetically sealed; however, for unconditioned or wash-down environments, a NEMA 4 rated enclosure is typically recommended.

Is the mounting hardware included?
The unit features an external mounting bracket for installation on uneven surfaces, but standard #8 self-tapping screws must be provided by the technician.
