The gas density relay calibrator, a fully automatic intelligent SF6 gas density relay calibrator (including SF6 gas density relay calibrator and SF6/N2 gas density relay calibrator), adopts embedded microprocessor and totally enclosed SF6 gas circulation system to conduct performance calibration on various SF6 gas density relays, normal temperature pressure gages and P20 pressure gages. The calibrator is used in production, maintenance and monitoring of SF6 gas products and is especially applicable in power system to provide convenience in production and safe running of SF6 electric products. Feature of SF6 Gas Density Relay Calibrator The instrument has built-in capsule replaceable gas chamber based on self-owned patent. Its calibration scope covers 0-1Mpa in full scale. Calibration work is stable and smooth and can be finished at one stroke without need of interruption for gas charging. The instrument has built-in capsule replaceable gas chamber and replace static seal with dynamic seal to improve airtightness of the instrument. During calibration, SF6 gas conducts internal circulation without discharge into atmosphere, which is more environment friendly and safer. It boasts dual-seal design consisting of hand valve and self-sealing valve in its structure. It is easy to operate and prevents moisture and air from entering pipe. There is no discharge or leakage of SF6 before and after calibration. Cleaning and air admission device has simple structure and is easy to operate. Cleaning and charging reduce mini water and foreign gas content inside it to the minimum level.
