China Ds18b20 temperature sensor Manufacturer
- PRODUCT DETAIL
It mainly changes its appearance depending on the application. The packaged DS18B20 can be used for cable trench temperature measurement, blast furnace water circulation temperature measurement, boiler temperature measurement, machine room temperature measurement, agricultural greenhouse temperature measurement, clean room temperature measurement, ammunition depot temperature measurement and other non-limiting temperature occasions. Wear-resistant and bump-resistant, small in size, easy to use, and various packaging forms, suitable for digital temperature measurement and control of various small space equipment.
1, Technical performance description:
①, a unique single-wire interface,DS18B20 in the connection with the microprocessor only need a port line to achieve the two-way communication with the microprocessor DS18B20.
②, temperature range -55 ℃ ~ +125 ℃, the inherent temperature error (note, not the resolution,Here before is wrong) 1 ℃.
③, support multi-point networking,Multiple DS18B20 can be connected in parallel on a single three-wire,Can only be 8 in parallel,To achieve multi-point temperature measurement,If the number is too large,Will make the power supply voltage is too low,Thus causing the signal transmission instability.
④, power supply: 3.0 ~ 5.5V / DC (parasitic power supply can be data lines)
⑤, in use does not require any external components
⑥, the measurement results in 9 to 12-bit digital serial transmission mode
⑦, stainless steel tube diameter Φ6
⑧, for DN15 ~ 25, DN40 ~ DN250 various media industrial pipe and small space equipment temperature measurement
⑨, the standard installation thread M10X1, M12X1.5, G1 / 2 "optional
⑩, PVC cable direct outlet or German ball junction box outlet,Easy to connect with other electrical equipment.
