Brass Housing Probe 3950 3380 3435 3977 NTC Temperature Sensor 

Overheating Protection Of NTC Temperature Sensor:

Overheat protection direct protection indirect protection.

The ntc temperature sensor can be directly connected to the load for small current situations to prevent overheating damage and protect the device.

For large current situations, it can be used for protection of relays, transistor circuits, etc.

In either case, the thermistor is tightly coupled to the device being protected so that there is sufficient heat exchange between the two, providing protection in case of overheating.

For example, a mutant thermistor sensor is embedded in the stator winding of a motor and connected in series with a relay.When the motor is overloaded, the stator current increases, causing heating.When the temperature is higher than the abrupt change point, the current in the circuit can change from a few tens of milliamps to a few tens of milliamps, so the relay operates to achieve overheating protection.
