The comprehensive line of Ashcroft diaphragm seals will meet a wide variety of application or installation requirements. Over 30,000 variations are possible with the types, connections and materials available.

Ashcroft® bimetal and Duratemp® gas actuated thermometers provide superior durability and dependability, precision temperature readings, 1% accuracy, hermetically sealed cases, and a Maxivision® dial to eliminate parallax error, ensuring accurate temperature readings. Ashcroft bimetal thermometers can be externally calibrated and are available as tamper resistant. The Everyangle™ connection allows you to rotate the dial 360° and angle it 180°.

Ashcroft temperature switches utilize a filled thermal system to sense temperature changes in a process. As the temperature changes, the fill reacts by vaporizing on increasing temperatures, while condensing on decreasing. This process creates pressure against a piston assembly. Which moves and transfers the action to a microswitch.
