sensor chamber from mechanical room
building envelope ensuring accurate tem-
perature reading.
• Precision 1/2” NPT threaded hub enables
trouble-free field installation
• More than 16 types of interchangeable
NTC thermistors, precision platinum,
nickel or balco RTDs are available for
....universal compatibility
RoHS
The TE-205-F Outdoor Air Temperature Sensor meets the rigorous requirements of building owners and control professionals who need reliable outdoor air temperature data. This rugged, reliable outdoor air sensor incorporates more than thirty plus years of product development and experience
drawn from millions of installations world wide in all types of climatological
situations. The TE-205-F features the well known MAMAC Systems temperature probe, carefully sealed in the aluminum enclosure to prevent building air from escaping across the sensor. The temperature probe features
cold rolled 304 stainless steel that is hermetically sealed to form a monolithic
encapsulated cavity for the sensor and is immune to failure caused by high
humidity, contamination, thermal shock and vibration. The flat probe end
provides a large thermally sensitive area and the sensor is in direct thermal
contact to the surface. As a result, extremely fast response is achieved to
changes in temperature. This product and process design combined with
automated manufacturing processes yields a rugged, reliable, repeatable
and stable outdoor air temperature sensor at a low cost.
