Built with a 300 stainless steel wetted path, it handles demanding environments where corrosion resistance is required. The switch features an SPDT contact form rated at 10 amps at 125\/250 volts AC and 3 amps at 480 volts AC, covering a wide range of control circuit applications. With a maximum pressure setting of 60 psi and a repeatability rating of 0.5%, this switch delivers consistent actuation performance. It is installed by licensed HVAC technicians, industrial maintenance technicians, and instrumentation professionals in systems requiring reliable differential pressure monitoring.\u003c\/p\u003e\n\u003cp\u003eThe DPD1T-H18SS suits residential and commercial HVAC systems, hydraulic lines, compressed air systems, and fluid process piping where differential pressure monitoring and control are required. The 1\/8 inch NPTF threaded ports allow direct connection to standard instrumentation ports. The 18-inch free leads provide wiring flexibility in tight enclosures or panel installations. Its operating temperature range of -65 degrees F to 165 degrees F makes it suitable for both low-temperature refrigeration circuits and higher-temperature process applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSPDT contact form rated 10A at 125\/250 volts AC and 3A at 480 volts AC\u003c\/li\u003e\n  \u003cli\u003eMaximum pressure setting of 60 psi with minimum deadband of 0.18 psi and maximum deadband of 0.32 psi\u003c\/li\u003e\n  \u003cli\u003e0.5% repeatability for consistent and reliable switching performance\u003c\/li\u003e\n  \u003cli\u003e300 stainless steel wetted materials for corrosion resistance in demanding media\u003c\/li\u003e\n  \u003cli\u003e1\/8 inch NPTF threaded connection for standard instrumentation port compatibility\u003c\/li\u003e\n  \u003cli\u003e18-inch free leads for flexible wiring in confined installation spaces\u003c\/li\u003e\n  \u003cli\u003eWide operating temperature range from -65 degrees F to 165 degrees F\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement differential pressure switch for HVAC, process, and fluid system applications requiring 1\/8 inch NPTF ported differential pressure control with SPDT switching.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified technician familiar with instrumentation and control wiring. De-energize the control circuit and isolate system pressure before connecting or disconnecting the switch. Verify that line pressure does not exceed the 60 psi maximum pressure setting before commissioning. Follow applicable NEC requirements when routing and terminating the free-lead electrical connections.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Pressure Setting\u003c\/strong\u003e: 60 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Deadband\u003c\/strong\u003e: 0.18 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Deadband\u003c\/strong\u003e: 0.32 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRepeatability\u003c\/strong\u003e: 0.5%\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContact Form\u003c\/strong\u003e: SPDT\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\u003eElectrical Connection\u003c\/strong\u003e: 18 inch free leads\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: NPTF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWetted Material\u003c\/strong\u003e: 300 Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Operating Temperature\u003c\/strong\u003e: -65 degrees F (-54 degrees C)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Operating Temperature\u003c\/strong\u003e: 165 degrees F (74 degrees C)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 5.69 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 3.88 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3.5 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: DPD1T-H18SS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BARKSDALE","offers":[{"title":"Default Title","offer_id":51542010954034,"sku":"DPD1T-H18SS","price":1276.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/daa6f7e52d9fc702fe7857ce24eaa32c.jpg?v=1785889501","url":"https:\/\/voomisupply.com\/products\/barksdale-dpd1t-h18ss-differential-pressure-switch-spdt-60-psi","provider":"Voomi Supply","version":"1.0","type":"link"}
