When the PTC air heater is used to heat liquid (such as water), the PTC heater plate will not be damaged after the liquid is dried.

So in addition to the sensors used in home appliances, sensor in the automobile application and fuel graulism and other related parameters measurement.

Long-term thermal overload protector switch will reduce the insulation level of circuit and even burn equipment or circuit; Can cause use hidden danger, light burn fuse, heavy make circuit burn, cause...

The thermal motor protection is designed according to the actual needs of the electrical control industry circuit protection device.

thermal motor protection can automatically clear false alarm information after short-term discontinuous electrical recovery, realize restart, greatly reduce the scope of the accident.

Refrigerator thermostat controller with time delay and the function of the temperature control, the time delay is to protect the refrigerator under the condition of sudden power off suddenly calls.

PTC air heater​ has the characteristic of automatic constant temperature, no temperature control system is needed, the PTC air heater can be directly energized.

PTC water heater is composed of PTC ceramic heating component and corrugated aluminum strip by high temperature adhesive.

At present, PTC thermal protection​ has been widely used in heaters, dryers, air curtain machines, air conditioners and so on.

However, thermal protection relay has fatal defects, including rough setting, large environmental impact, poor repeatability.

For the temperature type motor thermal protector (temperature switch), because the current does not pass through the bimetal sheet, the thermal effect of the current has little influence on the action...

Motor thermal protectors can be divided into two categories: temperature type and overcurrent type according to whether the sensing double plate is overloaded current.

However, motor thermal protector relay has fatal defects, including rough setting, large environmental impact, poor repeatability, large error and single function.

This kind of motor thermal protector mainly by single chip microcomputer as the controller, which can realize intelligent comprehensive protection of the motor.

Motor thermal protector is a kind of element that provides very reliable protection under the condition of overtemperature.

Motor thermal protector is if appliances appeared abnormal working state, to ensure that the temperature is less than (or less than) a control element can be manually reset temperature limit.

Motor thermal protector is a kind of element that provides very reliable protection under the condition of overtemperature.

The motor thermal protector looks like a pencil head. It is usually tied or pasted in the position where the stator winding temperature is relatively high.

The ideal motor thermal protector is not the most functional, nor the so-called most advanced, but should be the most practical. So what is practical?

Shear type and tooth insert type motor thermal protector because of inconvenient maintenance, easy to break teeth and other reasons can not adapt to the needs of modern industrial development, has bee...
