Description
Gas density is an important parameter related to the safe operation of high voltage switchgear. If the gas density does not meet the requirements, the safe operation of the equipment cannot be guaranteed.
The Wika Gas Density Meter reliably alarms for dangerous low gas concentrations even under extreme environmental conditions.
Once the device leaks and the gas density decreases, it will trigger the magnetic assisted electrical contact on the relay to perform the switching action. The electrical contact is driven by a pointer on the relay, which enables reliable switching and good repeatability.
Because gas pressure changes depend on factors such as ambient temperature, altitude, and atmospheric pressure, traditional pressure gauges are not applicable here.
The above factors such as ambient temperature, altitude and atmospheric pressure can affect the working pressure of gas up to 20%, which will greatly increase the probability of erroneous measurements.
In view of this, all Vika gas density meters are temperature compensated and hermetically sealed.
