      Component without harness connected

      (Room Temperature Sensor)
      *2 Sensing Portion
      *3 Resistance (kΩ)
      *4 Allowable Range
      *5 Temperature °C (°F)

      Measure the resistance according to the value(s) in the table below.

      Standard Resistance
      Tester Connection Condition Specified Condition
      E25-1 - E25-2 10°C (50°F) 3.00 to 3.73 kΩ
      E25-1 - E25-2 15°C (59°F) 2.45 to 2.88 kΩ
      E25-1 - E25-2 20°C (68°F) 1.95 to 2.30 kΩ
      E25-1 - E25-2 25°C (77°F) 1.60 to 1.80 kΩ
      E25-1 - E25-2 30°C (86°F) 1.28 to 1.47 kΩ
      E25-1 - E25-2 35°C (95°F) 1.00 to 1.22 kΩ
      E25-1 - E25-2 40°C (104°F) 0.80 to 1.00 kΩ
      E25-1 - E25-2 45°C (113°F) 0.65 to 0.85 kΩ
      E25-1 - E25-2 50°C (122°F) 0.50 to 0.70 kΩ
      E25-1 - E25-2 55°C (131°F) 0.44 to 0.60 kΩ
      E25-1 - E25-2 60°C (140°F) 0.36 to 0.50 kΩ

      Note


      • Hold the sensor only by its connector. Touching the sensor may change the resistance value.

      • When measuring, the sensor temperature must be the same as the ambient temperature.

      Tech Tips

      As the temperature increases, the resistance decreases (see the graph).

      If the resistance is not as specified, replace the room temperature sensor.
