MAMAC Systems TE-702-B-10-B Temperature Sensor

The MAMAC Systems TE-702-B-10-B is a high-precision duct temperature sensor engineered for demanding building automation systems (BAS) and mechanical equipment room applications. This industrial-grade unit features a 3,000 Ohm NTC thermistor sensor element, providing high-interchangeability and a stable resistance output for accurate environmental monitoring. The 1/4" O.D. 6-inch 304 stainless steel probe is hermetically sealed to prevent moisture migration, ensuring long-term signal integrity in high-humidity plenums or air handlers. Housed in a rugged 18-gauge NEMA 1 galvanized steel enclosure with welded seams, the TE-702-B-10-B temperature sensor is built to withstand mechanical shock and vibration within commercial HVAC ductwork. With an operating range of -40°F to 210°F (-40°C to 100°C), this sensor is a reliable choice for monitoring supply, return, or mixed air temperatures. Its 1/2-inch NPT conduit connection and terminal strip wiring simplify integration for contractors requiring a robust, field-proven solution for HVAC temperature control.

• Precision Monitoring: High-accuracy 3K Ohm NTC professional-grade thermistor for tight control loops.
• Durable Construction: 6-inch 304 stainless steel probe with a terminal-protected NEMA 1 steel housing.
• Wide Compatibility: Standard resistance output integrates seamlessly with most major BAS and DDC controllers.
• Environmental Protection: Hermetically sealed probe tip resists failures caused by condensation or thermal shock.

Common Questions

What is the resistance curve for this sensor?
The unit utilizes a standard 3,000 Ohm NTC thermistor curve, compatible with systems calibrated for 3K sensors at 77°F (25°C).

Can this be mounted in outdoor air ducts?
As a NEMA 1 rated device, this enclosure is designed for indoor use. For unconditioned or outdoor environments, a NEMA 4/IP-65 rated housing is typically recommended.

What is the proper insertion depth for accurate readings?
For best results, the 6-inch probe should be positioned in the center of the air stream to avoid boundary layer temperature fluctuations near the duct walls.
