Detailed introduction

Product introduction

HCMD-I density relay fully automatic school inspection instrument is an intelligent fully automatic SF6 density relay check instrument. This instrument uses a microcomputer technology to verify the various SF6 density relays, and a portable verification instrument that standardizes the pressure on the pressure of the SF6 gas at the ambient temperature of the SF6 gas. It is convenient for testing and maintenance.

In a sealed container, the SF6 gas pressure at a certain temperature can represent the SF6 gas density. In order to be able to be unified, the SF6 gas pressure at 20 ° C is often used as a standard value. During the on -site check, at different ambient temperatures, the measured pressure values ​​must be converted to the pressure value when it corresponds to 20 ° C, thereby judging the performance of the SF6 density relay. The HCMD-I density relay fully automatically completes this process, which is accurate, flexible and convenient. In addition to the SF6 density relay verification, this instrument also has the functions of verification and density tables of the pressure gauge and density table. Essence

Feature characteristic
