• Use the T775-SENS-OAT to measure outside air temperature Some typical applications for the 50021579-001 and T775-SENSWT/WR sensors include monitoring return air, discharge air, and mixed air temperatures Sensors have fast response time and highly accurate Sensors have 1/2 in. (6.35 mm) stainless steel probe with a thermally conductive epoxy Sensors are 1,097 Ohms PTC at 77xF (25C) The 50021579-001 is a standard temperature sensor for indoor applications The T775-SENS-WR is a water resistant sensor with 5 ft leads The T775-SENS-WT is a water tight sensor with 6 ft leads The T775-SENS-OAT is for sensing outdoor air temperature and is housed in a weatherproof case for outdoor use (knockouts allow for 1/2 in. conduit connection)

A family of general use, simple to use, broadly featured electronic temperature and universal controllers for use in HVAC, agricultural, and industrial applications.
