Thermistor Sensor
WT4
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
Features
- The fastest response by using a compact glass-encapsulated thermistor element
- Also applicable to warm air control and liquid level detection
