MAMAC Systems TE-705-B-17-B-1 Temperature Sensor

The MAMAC Systems TE-705-B-17-B-1 is a commercial-grade duct averaging temperature sensor designed to mitigate air stratification issues in high-airflow HVACR environments. This unit features a 12-foot bendable aluminum probe with a 3/8-inch diameter, allowing for a serpentine installation across large plenums to capture precise average supply air temperature. Equipped with a 20,000 Ohm NTC thermistor, the sensor provides high-resolution resistance data compatible with most major building automation systems (BAS). The NEMA 1 galvanized steel enclosure ensures durability in mechanical room conditions, protecting internal terminations from physical damage and dust. By integrating four evenly spaced sensor modules, the TE-705-B-17-B-1 eliminates the inaccuracies caused by thermal layering, ensuring your air handling unit (AHU) or rooftop unit (RTU) operates with optimal efficiency based on true mixed-air conditions. For contractors, the thin-wall aluminum construction facilitates manual shaping without kinking, simplifying the integration into complex ductwork transitions.

Key Benefits:

• Enhanced Accuracy: Multi-point duct averaging sensor technology prevents localized temperature spikes from triggering false HVAC control responses.
• Versatile Installation: The 12-foot flexible probe is easily adjustable for custom serpentine configurations in diverse duct dimensions.
• Industrial Durability: Rugged 18-gauge galvanized steel enclosure meets NEMA 1 standards for professional instrumentation.
• High Compatibility: Standard 20K Ohm NTC thermistor curve maps seamlessly to standard controller inputs for building automation systems.
• Fast Response: Environmentally sealed sensor modules provide rapid thermal transfer while remaining protected against condensation.

Common Questions:

How does this sensor handle air stratification?
Unlike single-point sensors, this 12-foot probe contains multiple modules that average the resistance across the entire length, providing a reliable reading even when hot and cold air layers are present in the duct.

Can the aluminum probe be cut to a shorter length?
No, the probe length is fixed because the sensor modules are factory-spaced. Cutting the aluminum tube would damage the internal wiring and sensor elements.

Is this sensor compatible with 10K or 3K systems?
This specific model (B-17) uses a 20,000 Ohm NTC thermistor. You must verify that your controller is configured for a 20K Ohm Type curve to ensure accurate temperature reporting.
