Ashcroft DS316L-PS Diaphragm Seal With Pressure Switch

Ashcroft DS316L-PS Diaphragm Seal With Pressure Switch is a diaphragm-seal assembly that combines a corrosion-resistant 316L stainless steel diaphragm seal with an integrated pressure switch to shield downstream instrumentation from aggressive process media while enabling reliable pressure actuation. The 316L diaphragm material delivers robust resistance to corrosive fluids, making the assembly suitable for demanding environments such as chemical processing, oil and gas, and pharmaceutical applications. By isolating the sensing element from the process fluid, the DS316L-PS transmits pressure through a fill medium to the switch, allowing accurate shutoff or alarm triggering without exposing the instrumentation to corrosive or dirty media. The design is intended for compatibility with Ashcroft pressure switches and their family of diaphragm-seal configurations, offering common process-connection options and mounting arrangements that integrate smoothly into existing instrumentation housings. In use, this combination provides a compact, robust solution for maintaining measurement integrity and control reliability in systems where diaphragm seals are preferred to protect sensors and extend instrument life.
