HVAC Raw Sensor HVAC Raw Sensor (746 KB)

Raw Sensor

The Sensor Scientific Raw Sensor enables accurate temperature measuring from remote locations. The thermistor assembly features vinyl housing with dimensions 0.20” dia x 1” and eight feet long PVC zipcord lead. The sensor operating range is from -10°C to +70°C (+14°F to +160°F). RTD ( Resistance Temperature Detector) with resistance values 100, 500, 1,000, & 2,000 Ohms at 0°C is also available as a temperature measuring element.


Features:

  • High Accuracy NTC Thermistor
  • Vinyl Housing
  • 8 FT Zipcord Lead PVC 22 AWG

Specifications:

  • High Accuracy +/- 0.2ºC ( 0 to 70ºC)
  • Standard Accuracy +/- 0.5ºC ( 0 to 70ºC)
  • Industrial Accuracy +/- 1ºC ( 0 to 70ºC)
  • Dissipation Constant 3 mW/ºC

Wiring: All electrical connections and wiring must comply with the National Electrical Code and with local electrical codes.

Ordering Information

Thermistor: Select the appropriate type of thermistor to suit your instrumentation. Minimum order 10 pieces.
