Thermistor Sensor


Heat, oil and solvent proof



Sensing part: fluorocarbon 
Wire: fluorocarbon


  • Excellent heat, oil and solvent proof with fluorocarbon sealing
  • Fixing bracket design is available
  • Applicable to high temperatures and highly accurate measurements
  • Showcase freezers (ambient); air conditioners for business use (water); oil coolers (oil)
  • Liquid level detection (using a PSB-3 glass-encapsulated thermistor element only)
Operating temperature -30 to +200℃
Please consult us when higher temperatures are required.
Thermal time constant PSB-S1 & PSB-N  τ ≒ 8 sec. (in stirred liquid)
PSB-S3       τ ≒ 4 sec. (in stirred liquid)
Dissipation constant PSB-S1 & PSB-N  δ ≒ 2mW/℃
PSB-S3       δ ≒ 1.2mW/℃
Withstand voltage 1200VAC for 1 sec.
Insulation resistance ≥100MΩ at 500VDC
Resistance R100 = 3.3kΩ Other options available
B constant B0/100 = 3970K Other options available

* Values in the above table are for reference only.
* Unless otherwise stated, the thermal time constant and the dissipation constant are measured in still air.
