Description 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.
