E1H membrane piston pressure switch is a mechanical pressure switch produced by Phoenix Contact, Germany. Its accuracy is ±2.0%. It is suitable for measurement ranges of -0.28 . -0.9 bar, 0.1 . 34 bar, and can be used in machinery and tool manufacturing, dosing machines, plant construction, and sprinkler monitoring.
This document provides technical specifications for the Barksdale E1H Membrane Piston Pressure Switch. It details the device's operating ranges, including vacuum (-0.28 to -0.9 bar) and positive pressure (0.1 to 34 bar), along with its repeatability accuracy of +2% at constant temperature.
The leaflet outlines construction materials such as NBR membranes with optional FKM or PTFE, anodized aluminum housings, and various process connection options like 1/4" NPT. It also lists electrical load capabilities for different contact types (silver or gold) and provides a table of pressure ratings versus proof pressures. This manual is written in German.
