PR-23SX-ETR-EI is an intrinsically safe explosion-proof pressure transmitter made by KELLER Switzerland. With Ex ia IIC T4 ATEX/IECEx certification, it can be installed in marine hazardous areas such as pump rooms and fuel tank compartments. The all 316L stainless steel laser-welded housing offers outstanding resistance to salt fog, fuel oil and seawater corrosion, working stably from -40℃ to +80℃. It outputs standard 4~20mA two-wire signal compatible with all marine PLC and control panels, with shielded cable to eliminate electromagnetic interference from engines and inverters. IP68 fully sealed construction prevents water and oil mist penetration, widely used as original replacement spare parts for marine air compressor, boiler and hydraulic pipeline pressure monitoring systems.
