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.
Advantages
- We have the heart of NTC temperature sensor--full sets of production line and core technology of pro-prietary intellectual property rights for high performance temperature measurement NTC thermistor.
- We have all kinds of NTC core element of NTC Temperature sensor--high performance temperature measurement thermistors are own production,complete series,structural diversity. Our products can meet the requirements of prevision measurement in different temperature area from low temperature,medium and low temperature to medium-high temperature.These products have passed many safety certifications of domestic and foreign.
- Resistance and temperature characteristics can meet customer's requirements entirely,and support best convenience to customers.
- Mature manufacturing technique of NTC temperature sensor,Large-scale mass production,product have the best ability of insulation sealing,Mechanical collision,resistance to bending,well-set.
- Small thermal time,fast response

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.
