NTC Thermsitor inside micro Temperature Sensor are temperature-sensitive resistors of negative temperature coefficient of resistance – resistance decreases exponentially with temperature increase. Thanks to their high sensitivity, the NTC thermistors are widely used as temperature sensors, temperature compensator, and inrush current limiter.

Micro Temperature Sensor are epoxy coated and is designed for general purpose of temperature sensing, measurement, or control in the applications. It can be integrated with silicone wires or tinned copper-cladded steel leads so as to meet various requirements of electrical interface.

 

The sensing element (NTC thermistor chip) of this series is located at the end the epoxy sealing. The epoxy sealing can be achieved in a small diameter for not only fast response time but also application in limited space.In addition, the customized NTC thermistors can be available on request, e.g., customized resistance, B constant, or length of the wires or leads.


 

How to get offer quickly with enough specification ?

 

1. Operating temperature range : ?

2. Application environment: ?

3. Material and dimension of Housing: ?

4. Specification of sensing element : ? NTC/DS18B20/RTD etc.

(For example: If sensing element is NTC Thermistor, then Resistance at 25degree is 10KOHM,Resistance tolerance is ±1% ; Beta value is 3950,Beta tolerance is ±1%)

5.Cable gauge and length

6. How to deal with tail of cable ? Only stripped and tinned ?Attach connector or stripped & tinned ? If attach connector,pls let us know part number of connector and we will recommend suitable one.

7. Any special requirements ? For example; Tolerance for sevaral temperature point etc.

8. Estimated quantity required
