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

The MAMAC Systems TE-701-B-7-A is a precision duct temperature sensor engineered for building automation systems and mechanical equipment monitoring. This model features a high-stability 10,000 Ohm NTC Thermistor (Type III) sensing element, providing highly accurate and repeatable resistance output for direct digital control (DDC) applications. The 4-inch 304 stainless steel probe is hermetically sealed to prevent moisture migration and contamination, ensuring long-term reliability in high-humidity airflow environments.

Designed for versatile field installation, the unit includes a rugged galvanized steel flange mount and is pre-wired with a 6-foot plenum-rated cable. This configuration is optimized for sensing air temperature in supply, return, or mixed air ducts within air handlers and fan coil units. The thin-wall probe design allows for rapid thermal response to fluctuating air temperatures, providing the sensitivity required for precise HVAC climate control and BAS integration.

Key Benefits

• Compatible with most major BAS controller protocols requiring a 10k Type 3 thermistor curve.
• Durable 304 SS probe construction protects the sensing element from thermal shock and vibration.
• Integrated flange mount with a gasketed surface ensures a tight seal to prevent duct leakage.
• Plenum-rated 6' cable meets fire safety standards for installation in air handling spaces.
• Wide operating range of -40°F to 210°F suitable for diverse commercial and industrial HVAC applications.

Common Questions

Can this sensor be used in high-moisture air handlers?
Yes, the stainless steel probe is hermetically sealed to protect the 10k ohm NTC thermistor from failure caused by condensation or high humidity.

Is the mounting flange included with the sensor?
The flange mount is integrated into the assembly, allowing for direct attachment to the duct wall using standard sheet metal screws.

What is the resistance curve for this model?
This unit utilizes a standard 10,000 Ohm Type III NTC thermistor curve, which is commonly supported by HVAC controllers from brands like Schneider, Andover, and Automated Logic.
