D PTC Thermistors for Overheat Sensing Protection Circuit Examples
E PTC Thermistors Limit Temperature Sensor for Industrial Application
A PTC thermistor can be used effectively to detect whether a temperature limit in industrial equipment, liquids, etc, is exceeded.
The PTC thermistor is mounted in thermal contact with the medium that has to be protected from overheating.
When the rated temperature limit of the medium is reached, the resistance of PTC thermistors increases abruptly.
In connection with a control unit, this signal can be used to automatically switch the power supply of a load.
F Typical Application of PTC thermistors Temperature Limiting Sensors
· Limit temperature measurement of Industrial electronics application.
· Power supplies, switch power supply.
· Home appliances, such as dish washers, washing machines, ironing machines, electric cookers, etc.
· Electronic data processing and communications engineering (DC/DC converters).
· Motor windings overheating Protection.
· Automotive electronics.
· Semiconductor heatsinks, enclosure panels, temperature-limited transistors.
· Lighting applications.
