Barksdale E1S-H15-PLS Pressure Switch 1/2 Npt Spdt 10A

Product Description

The BARKSDALE E1S-H15-PLS is a diaphragm piston pressure switch designed for industrial and mechanical system pressure monitoring applications. It features a polysulfone 40% glass-filled wetted body for chemical resistance and durability under demanding conditions. The switch uses an SPDT contact form with screw terminal electrical connections, rated at 10 amps at 125/250 volts AC and 3 amps at 480 volts AC. With a maximum pressure setting of 1000 psi and a repeatability rating of 2%, this switch delivers consistent, reliable actuation for pressure control and safety shutoff circuits. Licensed HVAC, plumbing, and mechanical technicians are the typical installers.

The E1S-H15-PLS is suited for use in residential and commercial mechanical systems where reliable pressure sensing is required. Its 1/2 inch NPT male thread connection allows straightforward integration into standard piping configurations. The wide operating temperature range of -20 degrees F to 165 degrees F makes it appropriate for both cold-ambient and warm-process environments. The minimum deadband of 0.1 psi and maximum deadband of 1.20 psi provide flexibility for fine-tuned pressure control setpoints across a variety of fluid and gas system applications.

Installation Notes

Installation should be performed by a licensed plumbing, HVAC, or mechanical technician. Depressurize and isolate the system completely before removing any existing pressure switch or fitting the new unit. Follow applicable local codes and the IFGC or IPC as appropriate to the system type. Do not exceed the rated maximum pressure or temperature limits of the switch during or after installation.
