Shibaura Electronics


Thermistor Sensor


The fastest response water temperature sensor for home appliances

Response is compared to other Shibaura water temperature sensors



Sensing part: stainless steel 
Wire: cross-linked fluororubber


  • The fastest response by using a compact glass-encapsulated thermistor element
  • Also applicable to warm air control and liquid level detection
Applications Water heaters ,heat pump water heaters,bidets
(instant outlet warm water & warm air)
Operating temperature -20 to +120℃ (except connector)
Thermal time constant τ ≤ 0.5 sec. (in stirred water)
Response time to 90% Approx. 1 sec. (in stirred water)
Dissipation constant δ ≒ 3.5mW/℃ (in stirred water)
δ ≒ 1.5mW/℃
Withstand voltage 750VAC for 1 sec.
Consultation up to 1800VAC for 1 sec.
