MAMAC Systems TE-701-B-7-D Sensor

The MAMAC Systems TE-701-B-7-D is a rugged duct temperature sensor engineered for precision monitoring in commercial HVAC and building automation systems. This unit utilizes a high-stability 10K Ohm Type III NTC Thermistor, ensuring accurate resistance output for controllers requiring a Negative Temperature Coefficient (NTC) signal. The 12-inch stainless steel probe is tip-sensitive, providing a rapid thermal response time to manage temperature fluctuations within the ductwork effectively. Designed for professional installation, it features a robust flange mount for direct attachment to duct surfaces and includes a 6-foot plenum-rated pigtail cable to meet strict building codes. With an operating range of -40°F to 210°F and an interchangeability accuracy of ±0.36°F, this sensor is a reliable choice for discharge air, return air, and mixed air sensing applications where long-term drift must be minimized and field calibration is unnecessary.

Technical Benefits for Contractors:

• Broad Compatibility: The 10,000 Ohm Type III Thermistor integrates seamlessly with most industry-standard BAS and DDC controllers.
• Engineered Durability: Features a moisture-resistant, 304 stainless steel probe capable of withstanding high-velocity airflow and corrosive environments.
• Streamlined Installation: The integrated flange mount and 6-foot plenum-rated leads reduce field labor and additional hardware requirements.
• High Precision: Maintains a tight ±0.36°F (0.2°C) accuracy across the primary operating range, ensuring systems run at peak efficiency.

Common Questions:

How do I verify the resistance of the TE-701-B-7-D in the field?
Using a calibrated multimeter set to the Ohms scale, you should measure approximately 10,000 Ohms at 77°F (25°C). Since this is a Type III thermistor, ensure your controller is configured for the correct resistance curve to prevent offset errors.

Is this sensor suitable for high-moisture plenum applications?
Yes, the MAMAC TE-701-B-7-D features a sealed probe and plenum-rated cable, making it suitable for air handling units where moisture or strict fire codes are a concern.

Can the 12-inch probe be shortened for smaller ducts?
No, the stainless steel probe is factory-sealed to protect the NTC thermistor. Cutting the probe will destroy the sensing element and void the technical specifications. For narrow ducts, consider a shorter probe model.
