T775 Series 2000 Sensors
A family of general use, simple to use, broadly featured electronic
temperature and universal controllers for use in HVAC, agricultural,
and industrial applications.
• Use the T775-SENS-OAT to measure outside air temperature.
• Some typical applications for the 50021579-001 and T775SENSWT/WR sensors include:
• Monitoring return air temperatures
• Monitoring discharge air temperatures
• Monitoring mixed air temperatures
• All sensors:
• Fast response time and highly accurate
• 1/2 in. (6.35 mm) stainless steel probe with a thermally conductive
epoxy
• 1,097 Ohms PTC at 77ÞF (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)
• Two year warranty
Application: For indoor use in applications such as monitoring return
air, discharge air, and mixed air temperatures
