Since 1852, Ashcroft has pioneered reliable pressure and temperature instrumentation to help protect people, equipment and environments. Our legacy of invention began with steam-powered safety and continues today through sensor-based and custom-engineered solutions trusted across the globe.

Ashcroft® pressure gauges are available in various sizes and accuracies, with a measurement range from 0 - 10 in. H2O to 0 - 100,000 psi. The product range is diverse, including differential pressure gauges, high-precision pressure gauges, sanitary pressure gauges, high-purity pressure gauges, deep-sea pressure gauges, and digital pressure gauges, etc. Ashcroft pressure gauges feature high quality and reliability, meeting the needs of various budgets and applications. 

Ashcroft® pressure switches offer a variety of configurations to meet the installation requirements of various industries. The product range is extensive, including differential pressure switches, explosion-proof pressure switches, NEMA 4 and NEMA 7 rated pressure switches, and electronic pressure switches. 

Ashcroft® pressure sensors/transmitters are designed to meet the demanding installation requirements of low or high temperatures, high shock and vibration. Our pressure sensors include various models for HVAC, food and beverage, biopharmaceutical, hydraulic and pneumatic, and semiconductor industries. The measurement range is from 0 - 0.01 in. H2O to 72,000 psi, with accuracy of ±0.25% to ±2.00% full scale. A variety of electrical terminals, process connections and analog output options are available to meet customer needs. 

Ashcroft® diaphragm seals are designed to protect valuable instruments from potential damage caused by corrosive media or clogging by sludge and mud, especially in wastewater treatment. The diaphragm seal products offer a variety of compatible wetted materials to choose from, such as 316 stainless steel, Monel alloy and tantalum. 

Ashcroft® offers a complete range of pressure accessories for protecting instruments and controlling pressure flow. Multi-way valves, pressure limiting valves, heat dissipation tubes, pulsation dampers, needle valves, pressure dampers and multi-valve groups are easy to install and improve operation.
