Barksdale E1H-H15-P6-BR Electronic Pressure Switch

Barksdale E1H-H15-P6-BR is a housed, diaphragm-seal piston pressure switch from the Econ-O-Trol family, designed for precise, single-setpoint control in low-pressure pneumatic and hydraulic applications and built around a diaphragm-seal piston mechanism with a plastic diaphragm. The H15 variant covers 0.5 to 15 psi (approximately 0.03–1.0 bar) and offers ±2.0% full-scale repeatability at constant temperature, with a single switching contact suitable for standard control circuits. The P6 process connection is 1/8" NPT female plus 1/2" NPT male, enabling straightforward integration with common tubing and piping, while the housed configuration provides robust protection for field installations. Optional configurations include intrinsically safe versions (Ex ia) and listed certifications (UL, CSA, DNV-GL) depending on the chosen configuration, making it suitable for hazardous environments when specified. Typical applications span machine-tool pressure regulation, general mechanical engineering, dosing equipment, and sprinkler or safety-control systems, where a compact, reliable pressure switch with a fixed setpoint is required.
