Detailed Product Description

Waterproof Thread Fixed Thermistor Temperature Sensor For Lithium Battery

Description

A temperature sensor is a device that detects and measures hotness and coolness and converts it into an electrical signal. We design and manufacture a broad portfolio of temperature sensors – including our NTC thermistors, RTDs, thermocouples, and thermopiles – designed for efficiency and easy installation, with capacity to reliably integrate technology that responds to human behavior.

Advantages and characteristics of Auto Temperature Sensor

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
Multi category,complete series,many kinds of housing he configuration,easy to assemble
We have high lavel inspection equipments which carrry out strict and normative inspection process.
Our products with high precision,high reliability,high stability,high interchangeable,high commonality are advanced in industry.

(Highest tolerance can be reach ±0.02℃) (Years of drif rate ≤1‰)

Operating temperature and environment of NTC temperature sensor depend on specific performance of its core element and lead wire:

►Different NTC thermistor using in the NTC temperature sensors with the following different operating temperature:

Chip or MF52A,MF51E,MF55: temperature resist grade 125℃,actual temperature resist grade 150℃
MF58: temperature resist grade 200℃,actual temperature resist grade 250℃
MF51: temperature resist grade 200℃,actual temperature resist grade 250℃
Special MF51: temperature resist grade 250℃,actual temperature resist grade 300℃
Weldless chip:temperature resist grade 450℃,actual temperature resist grade 500℃

►Operating environment

In the environment of high temperature,high humidty and high corrosion,we suggest to use glass sealed type thermistor as the core element.And MF51 type will be the best NTC thermistor in high humidity environment.

►Design considerations and procedure of temperature sensor:

1. Choose the shape acoording to customer's design or assemble requirements, and confirm the thermistor.
2. Confirm the thermistor element and other materials according to customers' requirement
3. Choose the suitable resistance,B value and tolerance
4. Choose suitable moisture-proof and insulation technology to meet customer's requirement
5. Choose suitable encapsulation structure to meet performance requirements of mechanical shock resistance
6. Meet customer's special requirements.
