MAMAC Systems TE-701-A-7-C Temperature Sensor

The MAMAC Systems TE-701-A-7-C is a professional-grade duct temperature sensor engineered for precise thermal monitoring in high-performance building automation systems (BAS). Featuring a 10,000 Ohm NTC Thermistor (Type III), this sensor provides exceptional stability and interchangeability for HVAC duct applications where consistent resistance-to-temperature curves are critical for controller accuracy. This specific configuration includes a 304 stainless steel probe with an 8-inch insertion length, making it ideal for monitoring average air temperatures in large supply and return air plenums. The flange mount design is fully gasketed to maintain duct pressure integrity and ensure a secure, vibration-resistant installation. Designed for rugged environments, the hermetically sealed terminal end protects the internal sensing element from moisture migration and contaminants. With 6" wire leads for direct BAS temperature sensor termination, the TE-701-A-7-C integrates seamlessly into existing mechanical equipment room instrumentation without the need for complex enclosures.

• Precise Thermal Response: Utilizes a 10K Type III NTC thermistor for high-accuracy resistance output compatible with most major HVAC controllers.
• Industrial Construction: Features a 1/4" O.D. 304 stainless steel probe and a galvanized steel flange for maximum durability in commercial air handlers.
• Gasketed Seal: The integrated flange gasket prevents air leakage and ensures accurate readings by isolating the sensor from ambient external temperatures.
• Versatile Application: Suitable for a wide range of environments, operating reliably from -40°F to 210°F (-40°C to 100°C).

• What is the difference between Type II and Type III 10K thermistors? Type III thermistors, like the one in this MAMAC Systems sensor, have a specific resistance-temperature curve (77°F = 10,000 ohms) that differs from Type II. Always verify your controller's input requirements to ensure proper calibration.
• Can this be used for outdoor air sensing? While the probe is stainless steel, this flange-mount model is specifically designed for duct temperature monitoring. For outdoor applications, a weather-shielded NEMA-rated enclosure is recommended.
• How is the TE-701-A-7-C installed? It requires drilling a 3/8-inch hole into the duct. The probe is inserted until the flange is flush, then secured using two #8 self-tapping screws.
