MAMAC Systems TE-707-B-12-A-1 Temperature Sensor

The MAMAC Systems TE-707-B-12-A-1 is a commercial-grade flexible averaging temperature sensor designed for precision air temperature monitoring in large HVAC ducts and plenums. Featuring a 10,000 Ohm NTC Thermistor (Type II), this sensor provides highly accurate resistance data compatible with most major building automation systems (BAS). Unlike rigid copper sensors that risk kinking and moisture ingress, this 6-foot plenum-rated cable utilizes four equally spaced sensing nodes, each epoxy-encapsulated and moisture-sealed via a patented process to prevent drift and intermittent shorts caused by condensation. The assembly is housed in a rugged 18-gauge NEMA 1 galvanized steel enclosure, ensuring durability in mechanical room environments. By measuring temperature across the entire duct cross-section, the TE-707-B-12-A-1 eliminates the "hot spots" and false freeze-stat trips common with single-point sensors, making it an essential component for effective HVAC duct averaging and energy-efficient climate control.

• High-Accuracy Sensing: Utilizing a 10k Type II thermistor, the sensor delivers reliable +/- 0.36°F (0.2°C) interchangeability for precise BAS integration.
• Moisture-Resistant Design: Patented sealing and a polyolefin sheath protect nodes from contaminants and high-humidity environments.
• Simplified Installation: The flexible CL3P plenum cable can be easily clipped or tied directly to coils and heat exchangers without the need for tube benders.
• Mechanical Protection: Aluminum stress-relief clips are crimped over each sensing module to withstand physical abuse during installation and operation.
• Broad Compatibility: Universal resistance output works seamlessly with systems from Kele, Johnson Controls, and other leading manufacturers.

• Can this sensor be used in return air plenums? Yes, the plenum-rated cable meets UL standards for installation in environmental air spaces.
• How does the averaging work? The sensor averages the resistance across four internal nodes, providing a true temperature mean rather than a single-point reading.
• Does it require a specific orientation? No, but for best results, the 6-foot probe should be phased across the face of the coil or duct to capture the full thermal profile.
