Temperature Sensors

C7021 10K ohm NTC Type II Temperature Sensors

The Series 2000 10K ohm NTC Electronic Temperature Sensors are designed for use with electronic controllers in domestic or commercial heating and cooling systems.

•B and C Model sense duct air temperature

•D models for immersion mounting sense water temperature

•F models sense outdoor air temperature and are weatherproof for outdoor use (knockouts allow for 1/2 in. conduit connection).

•J and R models sense average duct air temperature

•K models with strap-on mounting senses water temperature

•P models sense air temperature

•Solid state components not affected by dust or dirt

Sensor Type: 10 K ohm NTC @ 77 F Type II

Maximum Ambient Temperature: 302 F (150 C)

Shipping Temperature Range: -30 F to +160 F (-34 C to +71 C)

Used With: TB7600, TB7300, TB7200 Series communicating thermostats
