CE Refrigerator NTC Thermistor Sensors , Air Conditioner NTC Probe Temperature Sensor
High Sensitivity And Fast Response NTC Temperature Sensor Use For Refrigerator And Air Conditioner
Description
Thermistor probes are invaluable for sensing temperature levels in a variety of industries ranging from HVAC and food handling to automotive and laboratory research. In such applications, it's critical that the thermistor probe used is accurate to ensure reliable thermal monitoring.
A world-class provider of thermistors and thermistor probes and assemblies, We offers temperature probes designed and built from the ground up. The thermistors we use are created from a precise blend of raw materials and processed using proprietary techniques that result in superior discrete components, probes and assemblies.
We manufactures laboratory grade temperature probes, surface temperature sensing probes, micro probes, as well as many others designed to suit specific applications. Our application engineers are experts in the design of temperature sensing probes and assemblies utilizing thermistors as well as RTDs suitable for the most demanding applications.

Features
|
1. Wide operating temperature range, good stability and reliability.
2. Easy to installation and manipulation as the sealing can be done according to environment and conditions there it is applied by customer. 3. Accurate testing can reflect temperature change precisely. 4. Insulating resistance(MΩ): over 100MΩ at DC500 V 5. Working temperature range(°C): -10 to +105c 6. Dissipation factor(mw/°C): 1-2 (in still air) |
Working principle of temperature sensor
Using the NTC thermistor under a certain measurement power, the resistance value drops rapidly as the temperature rises. Utilizing this feature, the NTC thermistor can be used to determine the corresponding temperature by measuring its resistance value, so as to achieve the purpose of detecting and controlling the temperature.
