MAMAC Systems TE-701-B-12-A Temperature Sensor

The MAMAC Systems TE-701-B-12-A is a precision duct temperature sensor engineered for demanding building automation systems (BAS). This unit features a high-grade 10,000 Ohm NTC Thermistor (Type II), ensuring reliable resistance-to-temperature curves and high-accuracy signal output for HVAC controllers. The 4-inch probe length is fabricated from 304 stainless steel, providing structural integrity against high-velocity airflow while maintaining rapid thermal response times. Designed for versatile field installation, the flange mount temperature sensor includes a galvanized steel mounting plate and a 6-foot plenum-rated cable (CMP), meeting strict fire code requirements for installation within air distribution systems. This sensor is specifically calibrated to minimize drift, ensuring long-term stability in monitoring supply, return, or discharge air temperatures. The TE-701-B-12-A thermistor interface is compatible with most major DDC systems, including Johnson Controls, Honeywell, and Siemens, making it a standard choice for contractors requiring Type II 10k thermistor reliability in commercial environments.

• Precision Sensing: Utilizes a 10K Ohm Type II NTC thermistor for tight tolerance and accurate temperature tracking within the ductwork.
• Plenum Rated: Equipped with a 6-foot CMP-rated cable, eliminating the need for additional conduit in most drop-ceiling or air-handling applications.
• Rugged Construction: The 304 stainless steel probe resists corrosion and mechanical stress in high-moisture or high-airflow environments.
• Easy Installation: The integrated flange mount enables quick surface mounting to sheet metal ducts with standard self-tapping screws.
• Universal Compatibility: Standard 10K Type II curve matches the input requirements of the majority of industrial HVAC controllers and building management systems.

Is the TE-701-B-12-A compatible with my existing DDC system?
If your controller is configured for a 10,000 Ohm Type II NTC curve, this sensor will provide a seamless 1:1 replacement without requiring recalibration or offset adjustments.

Can this sensor be used in outdoor air intakes?
While the probe is stainless steel, the TE-701 series is primarily designed for indoor duct applications. For outdoor or high-humidity intake air, ensure the flange is properly sealed to the duct to prevent moisture ingress into the wiring junction.

How do I verify the sensor's accuracy in the field?
Technicians should use a calibrated multimeter to check the resistance across the leads. At 77°F (25°C), the sensor should read exactly 10,000 Ohms. Refer to the standard Type II resistance chart for other temperature points.
