MAMAC Systems TE-702-B-17-D Temperature Sensor

The MAMAC Systems TE-702-B-17-D is a high-precision duct temperature sensor engineered for demanding building automation systems and industrial HVAC applications. This model features a 20,000 Ohm NTC thermistor, ensuring stable resistance output and high-resolution data for environmental controllers. The 12-inch 304 stainless steel probe is hermetically sealed and crimp-attached to the enclosure flange, providing a monolithic barrier against moisture migration and contaminants within the air stream.

Housed in a rugged NEMA 1 galvanized steel enclosure, the TE-702-B-17-D is designed for rapid installation on uneven duct surfaces using the external mounting bracket. The keyed cover allows for easy access to wiring without fully removing screws, streamlining field maintenance. Capable of operating across a broad temperature range of -40°F to 210°F, this sensor delivers an accuracy of ±0.36°F (0.2°C), making it a reliable choice for monitoring supply, return, or discharge air in commercial AHUs and plenums.

• 20k Ohm NTC Thermistor: Provides high sensitivity and interchangeability for precise thermal monitoring in HVAC control systems.
• 12-Inch Stainless Steel Probe: Durable 304 SS construction resists corrosion and provides adequate reach for large-diameter ductwork.
• NEMA 1/IP-30 Enclosure: Heavy-duty 18-gauge galvanized steel protects internal terminations from physical damage and industrial debris.
• Fast Response Tip: Tip-sensitive design ensures immediate temperature updates for critical BAS air temperature monitoring.
• Contractor-Friendly Design: Features a 1/2-inch conduit opening and a swing-open cover to reduce labor time during field installation.

Is the TE-702-B-17-D compatible with my building automation system?
This sensor utilizes a standard 20,000 Ohm NTC thermistor curve. Always verify the resistance input requirements of your specific DDC controller to ensure signal compatibility.

Can this sensor be mounted in high-humidity environments?
The probe is hermetically sealed to prevent moisture from affecting the sensor element. However, the NEMA 1 enclosure is rated for indoor use; for applications where the enclosure is exposed to dripping water or heavy condensation, a NEMA 4 rated model is recommended.

Does the probe length affect the accuracy of the reading?
The 12-inch probe length is designed to reach the center of the air stream in larger ducts, which generally provides a more accurate representation of average air temperature than a shorter probe positioned near the duct wall.
