MAMAC Systems TE-704-A-12 Temperature Sensor

The MAMAC Systems TE-704-A-12 is a professional-grade surface mount strap-on temperature sensor designed for accurate thermal monitoring of pipes and vessels in HVAC building automation systems. This field-proven unit features a high-precision 10,000 Ohm NTC thermistor (Type II) element, ensuring reliable resistance output with an interchangeability of ±0.2°C. Engineered for durability, the TE-704-A-12 incorporates a 2-inch 304 stainless steel probe and a 6-foot plenum-rated cable, making it suitable for installation in air handling spaces and return air ducts. Its rugged construction includes a 30% glass-filled polycarbonate enclosure, which protects the internal sensing components from mechanical shock and vibration. Designed for contractors, this pipe temperature sensor includes nylon ties for rapid securing to conditioned water pipes, low-pressure steam lines, or refrigerant tubing, providing a cost-effective solution for real-time equipment room instrumentation.

• Universal Compatibility: The 10K Type II thermistor element integrates seamlessly with most major DDC and building management systems.
• Industrial Build Quality: Features a moisture-resistant stainless steel probe and a UL 94V-5-0 rated flame-retardant housing for long-term field stability.
• Easy Installation: Includes 6-foot pigtail leads and a strap-on design that eliminates the need for thermal wells or system shutdowns.
• Wide Operating Range: Accurately senses surface temperatures from -40°F to 210°F (-40°C to 100°C) for versatile heating and cooling applications.

What is the resistance value of the TE-704-A-12?
This model utilizes a 10,000 Ohm NTC Type II thermistor, reaching its nominal resistance at 77°F (25°C).

Can this sensor be used on steam lines?
Yes, it is suitable for low-pressure steam lines, provided the surface temperature does not exceed the maximum operating limit of 210°F.

What type of wiring is required for this sensor?
The unit comes with a 6-foot (1.8m) plenum-rated cable, allowing for direct hardwired connection to your controller's analog input without requiring additional conduit in many jurisdictions.
