Sensotec 911-FMD 1862-34 911FMD186234 Pressure Transmitter

The Sensotec 911-FMD 1862-34 (911FMD186234) is an FM-approved wet/wet differential pressure transmitter built for hazardous environments, offering a 3.0 psi differential range with a two-wire 4–20 mA output powered from 15–50 VDC. Wetted and housing components are 17-4 PH stainless steel, with a 1/4-18 NPT female pressure port and 1/2-14 NPT electrical termination (22 AWG) with a case ground, making it robust against liquids and corrosion. For the 911FMD family, typical operating temperature is 0–180 °F with a compensated range of 60–160 °F, and accuracy is about 0.25% of span. Commonly used in oil refining and drilling applications where rugged, hazardous-location differential pressure sensing is required.
