Ashcroft B424V XFSNH07 Pressure Switch, 0-200 PSI

The Ashcroft B424V XFSNH07 is a robust industrial pressure switch designed for precise control in demanding environments. This model features a watertight NEMA 4X enclosure, making it suitable for applications in oil and gas, chemical processing, power generation, and water treatment systems where reliable pressure monitoring is critical. It offers a adjustable set point range of 0-200 PSI with a proof pressure of 700 PSI, ensuring durability under high-pressure conditions. Key benefits include high accuracy, repeatable switching, and resistance to vibration and shock, thanks to its stainless steel and Viton construction. The switch provides SPDT contacts with electrical ratings up to 15A at 480VAC, allowing integration with various control systems. Compared to similar products like those from Dwyer or United Electric, the Ashcroft B424V excels in long-term reliability and a wider deadband adjustment (7-18.2 PSI), reducing nuisance trips. However, it may require periodic calibration in corrosive environments. Drawbacks include a higher initial cost and the need for professional installation to maintain certifications like UL and CE. From the provided images, the unit appears used with minor wear on labels and enclosure, but functional, with no visible damage to the 1/2" NPT brass process connection. Serial number D5002782 is noted on the faceplate. No parent/child assets are attached.
