Barksdale P1H-K340SS-T Stainless Steel High Pressure Switch

The Barksdale P1H-K340SS-T is a durable, diaphragm-sealed piston pressure switch engineered for high-pressure monitoring in demanding industrial settings. Produced by Barksdale Inc., a specialist in control devices, this model offers an adjustable pressure range of 6 to 340 psi (41 to 2344 kPa), with a high proof pressure of 2000 psi, making it ideal for hydraulic systems, process automation, safety interlocks, and equipment protection. Its stainless steel construction provides excellent corrosion resistance and longevity in harsh environments, such as chemical processing, oil and gas, or manufacturing plants. Key features include external adjustment for easy setpoint changes, NEMA 4 and 12 enclosure ratings for dust and water resistance, and versatile electrical ratings supporting AC and DC voltages up to 480V. Advantages over competitors like Ashcroft or Dwyer switches include superior repeatability (±1% accuracy), robust build for high-vibration areas, and compatibility with aggressive media. Potential drawbacks are its premium pricing and the need for periodic calibration in extreme conditions. Based on images, this unit appears to be new excess (NE) OEM stock, in excellent condition with original packaging, no visible wear, and includes faceplate details like serial number 2006 A0J51. It stands out for reliability where failure could be costly, though it may require professional installation for optimal performance.
