Product Introduction: The SF6 gas density relay calibration device is primarily used for the production, maintenance, and monitoring of SF6 gas products. It is suitable for the power system, providing convenience for the production, operation, pre-testing, and maintenance of SF6 electrical products. SF6 electrical products have been widely used in power departments, industrial mines, and enterprises. By adopting embedded microcomputer technology and importing high-performance pressure and temperature sensors, the calibration device resolves the difficulty of field calibration for RTSF6 gas density relays. The calibration device simultaneously samples the gas pressure and temperature during the operation of the tested relay and automatically converts them into standard pressure values at 20℃, thus achieving dynamic automatic compensation for pressure and temperature. Therefore, this calibration device eliminates the need for a constant temperature chamber required in traditional experimental methods, while also avoiding significant waste of SF6 gas.
