Barksdale D1H-H18SS Diaphragm Pressure Switch

The Barksdale D1H-H18SS is a high-reliability diaphragm pressure switch designed for precise pressure monitoring and control in industrial applications. It features an adjustable setpoint range of 0.4 to 18 PSI, with a proof pressure rating of 60 PSI, making it suitable for low-pressure systems where accuracy and durability are critical. Constructed with a stainless steel diaphragm and housing, it offers excellent corrosion resistance and longevity in harsh environments, such as hydraulic systems, pneumatic controls, and process automation. Key benefits include hermetically sealed contacts for explosion-proof operation, high vibration resistance, and easy installation with NPT connections. Compared to similar products like those from Ashcroft or Dwyer, the D1H-H18SS provides superior repeatability (±1% of full scale) and a wider operating temperature range, reducing maintenance needs. Drawbacks may include higher cost for premium materials and limited suitability for very high-pressure applications beyond 60 PSI. Ideal for use in oil and gas, aerospace, and manufacturing sectors, this switch ensures reliable switching with SPDT contacts for normally open or closed configurations.
