MAMAC Systems TE-705-B-5-C-1 Temperature Sensor

The MAMAC Systems TE-705-B-5-C-1 is a professional-grade duct averaging temperature sensor engineered for precise air temperature monitoring in large air handling units and plenums. Featuring a 1,000 Ohm Balco RTD element, this sensor delivers a high temperature coefficient of resistance (4,300 PPM/K), ensuring stable and accurate resistance-to-temperature linear curves across a wide operating range of -40°F to 250°F. The 24-foot bendable 3/8-inch aluminum probe houses four evenly-spaced, environmentally sealed sensor modules that eliminate errors caused by air stratification, providing a true average reading of the across-the-duct environment. For terminal protection, the unit is equipped with a rugged NEMA 1 galvanized steel enclosure, making it a reliable choice for building automation systems (BAS) and industrial HVAC control applications. This sensor is fully RoHS compliant and designed for direct integration with energy management systems that require high-density, multi-point sensing for optimal thermal efficiency.

Key Benefits

• Ensures high accuracy in stratified air environments using averaging temperature sensing.
• Features a durable 18-gauge galvanized steel NEMA 1 enclosure for superior protection in mechanical rooms.
• Equipped with a 24-foot bendable aluminum probe for versatile installation in large-scale air ducts.
• Utilizes a 1k Ohm Balco RTD sensor for reliable compatibility with various HVAC controllers.
• Environmentally sealed sensing modules prevent moisture migration and corrosion in high-flow air streams.

Common Questions

How should the averaging probe be installed to prevent air stratification errors?
For accurate duct temperature monitoring, the 24-foot probe should be uncoiled and routed across the entire cross-section of the duct. Avoid installation near heating/cooling coils or dampers where air temperature is not uniform; the bendable 3/8-inch aluminum construction allows for custom serpentine layout to cover the maximum surface area.

Is this sensor compatible with my existing building automation system?
The MAMAC TE-705-B-5-C-1 uses a 1,000 Ohm Balco RTD element. You must verify that your controller is configured to accept a Balco 1k signal. These are widely used in legacy and modern energy management systems due to their linear response and stability.

What is the enclosure rating for this temperature sensor?
This model features a NEMA 1 galvanized steel enclosure (IP-30 rated), designed for indoor applications where protection from dust and physical damage is required but exposure to direct water or extreme weather is not expected.
