About the battery-operated Ex i explosion-proof pressure gauge (CPG1500 model / NETRIS3 model)

Recently, the demand for mechanical measuring instruments on-site has been shifting towards instruments equipped with wireless units for field instructions and data transmission. These instruments often come with long-lasting batteries and are frequently installed in explosion-proof areas.
In such environments, two types of explosion-proof designs, Ex i or Ex d, are generally preferred. For pressure gauges and other measuring instruments, these are electrical devices that must be suitable for the atmosphere according to the relevant approvals.
Intrinsic safety explosion-proof design completely prevents the equipment from igniting explosive atmospheres, and the values of power, current, and voltage are kept low accordingly. Furthermore, there is a possibility that ignition sources may exist within the instrument itself. Therefore, the housing must be designed to be explosion-proof, ensuring that any potential explosion does not leak to the outside.
WIKA's pressure measuring instruments with battery operation and ignition protection type Ex i, such as the high-precision digital pressure gauge model CPG1500 and the Bourdon tube pressure gauge model PGU, along with the wireless unit model NETRIS3, have many installation records in environments like the one described above.
