School Fire Monitor Temperature Sensor

Details
Material: NTC glass-sealed thermistor/plastic cable tie/Teflon wire

Applicable temperature range：-30~150℃

Output signal: analog signal output

Advantages
1. Fast cable tie shell, which can be quickly installed and used.

2. Good stability and high reliability

3. Wide resistance range: 2~500KΩ

4. High resistance and B value accuracy

5. Glass package, can be used under high temperature and severe change

6. Small size, sturdy structure, easy for automatic installation

7. Operating temperature range -30~+150℃

8. Fast heat induction and high sensitivity

Application
Applications of fire alarm using thermistor include temperature measurement of fire-fighting corridors, school fire-fighting temperature monitoring, school high-temperature smoke detector and fire alarm heat detector for the dormitory, etc.

Note: What is the B value:
A material constant that describes the resistance-temperature relationship. The value of B can reflect the scale of resistance to temperature change between two specific temperatures. As the temperature changes, the resistance value of a product with a large B value under the same conditions changes more, that is to say, it is more sensitive.
