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.\u003c\/p\u003e\u003cp\u003eThe 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.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDiaphragm piston switching mechanism for reliable pressure actuation\u003c\/li\u003e\n\u003cli\u003ePolysulfone 40% glass-filled wetted material for chemical and pressure resistance\u003c\/li\u003e\n\u003cli\u003eSPDT contact form with screw terminal connections for easy field wiring\u003c\/li\u003e\n\u003cli\u003eRated 10A at 125\/250 volts AC and 3A at 480 volts AC\u003c\/li\u003e\n\u003cli\u003eMaximum pressure setting of 1000 psi with 2% repeatability\u003c\/li\u003e\n\u003cli\u003eDeadband range of 0.1 psi to 1.20 psi for adjustable switching differential\u003c\/li\u003e\n\u003cli\u003eOperating temperature range of -20 degrees F to 165 degrees F\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement pressure switch for mechanical systems requiring a 1\/2 inch NPT male thread SPDT diaphragm piston pressure switch rated to 1000 psi.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation 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.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSwitch Type\u003c\/strong\u003e: Diaphragm Piston Pressure\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContact Form\u003c\/strong\u003e: SPDT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Pressure Setting\u003c\/strong\u003e: 1000 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage Rating\u003c\/strong\u003e: 10A at 125\/250 volts AC; 3A at 480 volts AC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRepeatability\u003c\/strong\u003e: 2%\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Deadband\u003c\/strong\u003e: 0.1 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Deadband\u003c\/strong\u003e: 1.20 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: NPT Male\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eElectrical Connection\u003c\/strong\u003e: Screw Terminals\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWetted Material\u003c\/strong\u003e: Polysulfone 40% Glass Filled\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Temperature\u003c\/strong\u003e: -20 degrees F (-29 degrees C)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Temperature\u003c\/strong\u003e: 165 degrees F (74 degrees C)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 3.94 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 2.41 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1.94 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.75 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: BARKSDALE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: E1S-H15-PLS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BARKSDALE","offers":[{"title":"Default Title","offer_id":51541441675570,"sku":"E1S-H15-PLS","price":374.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2bf329a44eb9a7b9e801d1a1dd3f726f.jpg?v=1785876270","url":"https:\/\/voomisupply.com\/products\/barksdale-e1s-h15-pls-pressure-switch-1-2-npt-spdt-10a","provider":"Voomi Supply","version":"1.0","type":"link"}
