MAMAC Systems TE-702-A-4-C Temperature Sensor

The MAMAC Systems TE-702-A-4-C is a high-precision duct temperature sensor engineered for demanding building automation and industrial air handling applications. This model is equipped with a 1,000 Ohm Nickel RTD (Resistive Temperature Detector) featuring a 6000 PPM coefficient, providing the high sensitivity and linear response necessary for accurate environmental monitoring. Designed for field durability, the unit features an 8-inch 304 stainless steel probe with a cold-rolled, hermetically sealed tip to protect the sensing element from moisture, high humidity, and vibration. The lightweight polycarbonate plastic enclosure is glass-filled and UL 94V-5-0 rated, offering a rugged housing that simplifies overhead installation. This sensor is ideal for integration with HVAC controllers requiring a 1k Ohm Nickel RTD signal to monitor supply or return air temperatures in plenums and ducts. With its positive temperature coefficient (PTC), it ensures reliable data transmission for centralized BAS platforms without the drift associated with standard thermistors.

• Precision Sensing: Features a 1,000 Ohm Nickel (6000 PPM) sensor for reliable temperature detection across a wide thermal range.
• Rugged Construction: An 8-inch, corrosion-resistant 304 stainless steel probe ensures longevity in high-velocity airflows.
• Universal Compatibility: Standard resistance output integrates seamlessly with most professional grade HVAC controllers and BAS.
• Simplified Installation: The durable polycarbonate enclosure provides a low-profile footprint suitable for tight mechanical spaces.
• Environmental Protection: The IP54-rated housing and hermetic seal prevent failures caused by condensation or chemical exposure.

Is the MAMAC Systems TE-702-A-4-C compatible with my existing controller?
This unit uses a 1k Ohm Nickel RTD (6000 PPM) element. You must verify that your BAS or HVAC controller is configured to accept a Nickel (not Platinum) 1,000 Ohm signal with a 6,000 PPM/K temperature coefficient.

Where should I mount this sensor for the most accurate readings?
For optimal performance, install the 8-inch probe in a location that samples the average air stream. Avoid mounting near coils, discharge fans, or areas subject to air stratification which can lead to false readings.

What is the temperature range for this sensor?
The RTD element and probe assembly are typically rated for operations between -40°F and 210°F (-40°C to 100°C), making it suitable for both heating and cooling stages.
