PTC Thermistor for Air Heating
PTC Thermostatic Heater for Internal Insulation of Instrument and Equipment Chassis in Low-Temperature Environments
Usage Precautions
Use a hair dryer to remove heat to increase heating power. Wind speed significantly affects heating power. Generally speaking, the higher the wind speed, the greater the power. Without wind, the heater will not be damaged, but the power will drop significantly.
1) The power aging rate is within 10% after 1000 hours, and the resistance aging rate is within 50%.
2) Can be manufactured to customer specifications.
3) Available in both insulated and non-insulated configurations.
PTC Thermostatic Heater for Control Cabinet Dehumidification and Moisture Prevention
Suitable for heating and moisture prevention in electrical control cabinets, dehumidifying and moisture prevention in drying ovens, dehumidifiers, electric humidifiers, moisture prevention and heating for electrical instruments, monitors, electric ovens, medical equipment, household appliances, small appliances, and more.

How to Select High Accuracy ntc Temperature Sensor？
NTC thermistor has a high resistance at low temperature, and as the temperature increases the resistance decreases rapidly. Therefore NTCs offer the benefit of highly accurate and quick response times to very small changes in temperature. NTC thermistors are available with high accuracy, but typically over much narrower temperature ranges, such as 0 °C to +70 ° C.
NTC Thermistor Sensor Probe Assembly
NTC cable probe assembly with metal tube, silicone cable. Series: FTR2SIL Measuring Range: -50 a 180 °C Sensor: NTC, Pt100 or Pt1000 Cable Material: Silicon. This probe consists of a NTC thermistor soldered to a 24 AWG Stranded TPE cable and potted in a copper housing. The assembly is leaving over molded. The NTC Thermistor sensor system uses NTC sensor elements 1K, 2K, 5K, 10K, 100K, 1000K; B values 3375k, 3470K, 3950K, 3700k, 3935k, 3380k, 3450k, 3550k, 3600k, 3977k, 3950k.
