PRODUCT DATA
FEATURES
• C7031D, C7041D for immersion mounting sense water
temperature.
• C7031G, C7041F sense outdoor air temperature and
are weatherproof for outdoor use (knockouts allow for
1/2 in. conduit connection).
• C7031J, C7041J,R sense average duct air temperature.
• C7031B, C7041B,C sense duct air temperature.
• C7041K with strap-on mounting senses water
temperature.
• C7041P senses air temperature.
• Solid state components not affected by dust or dirt.
APPLICATION
The Series 2000 C7031, C7041 Electronic Temperature
Sensors are designed for use with electronic controllers in
domestic or commercial heating and cooling systems.
SPECIFICATIONS
Compatability: Use Series 2000 C7031, C7041 Temperature
Sensors with Excel 10, 15, 80, 100, and 500 controllers.
Series 2000 C7031B,D,G,J sensors are compatible with
various Honeywell controllers. The C7031G2014 is
compatible with the T7350 Commercial Thermostat.
Dimensions: See Fig. 1 through 9.
Sensor Accuracy: ±0.36°F at 77°F (±0.2°C at 25°C) for 20K
ohm NTC sensors.
Accessories:
32006523-001 20K Probe: to allow replacement of old style
C7031D1062-1 with non-threaded well.
50001774-001 Stainless Steel 304 Well Assembly: 1/2 in.
external and internal NPT threading. Use with C7031D/
C7041D.
50001775-001 Well Adapter: Used with C7031D/C7041D to
allow threading sensor into previously-installed Series 1000
32005960-001 Well.
