Thermistor Sensor


Heat, oil and solvent proof



Sensing part: fluorocarbon 
Wire: fluorocarbon


  • Excellent in heat, oil and solvent resistance with fluorocarbon sealing
  • Fixing bracket design is available
  • Applicable to high temperatures and highly accurate measurements
  • EV/HEV motors & inverters (solid)
  • Liquid level detection (using PSB-S3 glass-encap. thermistor element only)
Operating temperature -30 to +200℃
Please consult us when higher temperatures are required.
Thermal time constant PSB-S1 τ ≒ 8 sec. (in stirred liquid)
PSB-S3 τ ≒ 4 sec. (in stirred liquid)
Dissipation constant PSB-S1 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 constantare measured in still air.
