VVT
Type R2
Description： This temperature sensor adopts platinum resistance PT1000/PT250/PT100/PT500, with heat resistance and good stability.
Features： 1.Wide temperature range from -50°C to 550°C.
2.High temperature accuracy Advanced products can be accurate to 0.1°C.
3.Good long-term stability The change in resistance after 1000 hours of operation at 400°C is less than 0.04%.
4.Good product consistency, good interchangeability of products of the same level, and can be freely replaced.
5.Good batch consistency Different batches of products can be interchanged without changing the circuit.
6.Good environmental adaptability Special ceramic structure protection, strong and can withstand various Environments.
