MAMAC Systems TE-702-B-12-D Temperature Sensor
The MAMAC Systems TE-702-B-12-D is a rugged duct temperature sensor engineered for precision air-stream monitoring in demanding commercial HVACR environments. This model features a high-stability 10,000 Ohm NTC Thermistor (Type II), known for its tight interchangeability and accurate resistance-to-temperature conversion across a wide operating range of -40°F to 210°F. The 12-inch 304 stainless steel probe is hermetically sealed to the enclosure flange, providing a robust barrier against moisture migration that often compromises unsealed sensors in high-latent load applications.
Housed in an 18-gauge NEMA 1 galvanized steel enclosure, the TE-702-B-12-D is designed for direct mounting to ductwork or plenums with integrated 1/2-inch conduit knockouts for standard electrical fittings. The keyed hinged cover allows for rapid field wiring and resistance checks without removing the entire faceplate, streamlining BMS sensor installation and routine maintenance. Whether you are performing a duct sensor replacement or commissioning a new air handling unit, this passive sensor provides the repeatable signal necessary for critical discharge air and return air control loops.
Key Benefits for Contractors
- High Accuracy: The 10k Type 2 thermistor offers ±0.36°F (0.2°C) precision, essential for tight temperature control in building automation.
- Extended Probe Reach: The 12-inch length ensures the sensing element is positioned in the center of the air stream, avoiding the "dead-leg" measurement errors common in large ducts.
- Industrial Grade Build: Galvanized steel enclosure provides superior mechanical protection and shielding in mechanical rooms compared to plastic alternatives.
- Fast Response: The thin-wall stainless steel probe design facilitates rapid thermal transfer for near-instantaneous feedback to the controller.
Common Questions
How do I verify the accuracy of the TE-702-B-12-D in the field?
Use a calibrated ohmmeter to measure the resistance across the pigtails and compare the value to a standard 10k Type II thermistor chart. At 77°F (25°C), you should see exactly 10,000 ohms. Any significant deviation after system stabilization usually indicates a wiring issue or probe contamination.
What is the best placement for this duct sensor?
For accurate HVAC air temperature measurement, install the probe at least three duct diameters downstream from coils, humidifiers, or dampers to avoid the effects of stratified air or turbulent zones that skew readings.
