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.
General parameters
| ResistanceR25℃： | 5K | 10K | 15K | 20K | 50K | 100K | 200K |
| B value(R25/R50) | 3380 | 3950 | 3470 | 4200 | 3977 | 4100 | 4200 |
| Tolerance | 1% | 2% | 3% | 5% |
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.
