MAMAC Systems TE-705-B-1-C-1 Sensor

The MAMAC Systems TE-705-B-1-C-1 is a robust duct averaging temperature sensor specifically engineered for high-performance building automation systems and large-scale HVAC scale plenums. Designed with a 24-foot bendable 3/8" aluminum probe, this unit utilizes four environmentally sealed sensor modules to provide a precise composite average temperature across the air stream, effectively mitigating the reading errors caused by air stratification in high-flow environments. As a direct replacement for the Johnson Controls TE-6338P-1, it features a 100 Ohm Platinum RTD element with a standard TCR of 0.00385 ohms/ohm/°C, ensuring high accuracy and long-term stability without the drift common in thermistor-based alternatives. The sensor is housed in a heavy-duty NEMA 1 galvanized steel enclosure (18ga), making it a durable choice for mechanical equipment rooms and sensitive commercial ductwork applications.

Key Benefits:

• Precise Averaging: Incorporates four evenly spaced modules along the 24' probe to provide a true weighted average in large cross-section ducts.
• Rugged Construction: The 3/8" diameter thin-wall aluminum probe is fully bendable for custom field shaping while maintaining structural integrity.
• Direct Compatibility: Engineered as a drop-in replacement for the TE-6338P-1 and other standard 100 Ohm Platinum RTD sensing applications.
• Environmental Protection: Sensing elements are moisture-sealed to prevent failures linked to condensation in supply air streams.
• Technical Standard: Meets DIN 43760 standards with a ±0.1% accuracy at 0°C (32°F).

Common Questions:

Is the TE-705-B-1-C-1 compatible with my existing DDC controller?
Yes, provided your controller is configured for a 100 Ohm Platinum RTD (Alpha 385) input. This is an industry-standard curve used by major manufacturers like Johnson Controls and Honeywell.

How do I install the 24' probe to ensure accurate averaging?
The probe should be uncoiled gently and zig-zagged across the duct area using mounting clips. For best results, avoid placing sensors near heating/cooling coils or where air is highly stratified without mixing.

What is the operating temperature range for this sensor?
This model is rated for an operating temperature range of -40°F to 210°F (-40°C to 100°C), making it suitable for both heating and cooling applications.
