PTC Thermistors Limit Temperature Sensor
PTC thermistor can be ideal devices for temperature detection, monitoring, indicating, limiting and over (excessive) temperature protection, due it switches at one particular temperature.
PTC Thermistors Limit Temperature Sensor Description
PTC (positive temperature coefficient)thermistor switches at one particular temperature. Making use of the characteristics that the resistance of PTC thermistor increases sharply above curie temperature, when ambient temperature increases abnormally, protective circuit installed PTC thermistor will turn on or cut off loop through resistance changing, achieving thermal protection purpose. PTC thermistor protect such equipment and components as motors, transformers, power transistors and thyristors against over-temperature. A PTC thermistor is less expensive than a thermostat, and its switch temperature can be more accurately specified. It is also smaller and easier to design-in to electronic circuitry. Therefore PTC thermistor can be ideal devices for temperature detection, monitoring, indicating, limiting and over (excessive) temperature protection.Typical Application of PTC Thermistor for Temperature Protection and 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.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 thermistor increases abruptly.In connection with a control unit, this signal can be used to automatically switch the power supply of a load. Features of PTC Thermistor for Temperature Protection and temperature limiting sensors
·2 Outlook construction: A-radial leaded epoxy resin coated form, B-metal tag lug form. Screw type metal cases or other construction can be made upon customer request.
·PTC Thermistor Protection temperature 60C to 130C. 60C, 70C, 80C, 90C, 100C, 110C, 120C, 130C.
·Quick response.
·Long stability.
·Small dimension, convenient for installation.
·Do not need to be reset after protection.
