Ashcroft F-Series Explosion Proof Compact Pressure Switch
The Ashcroft® F-Series switch line of compact, adjustable pressure switches is designed to satisfy most requirements for alarm, shutdown, control and interlock on a wide variety of process and equipment applications. Electromechanical pressure switches are usually more cost effective than transmitters for these applications. Materials of construction have been selected for long life. A wide variety of precision switch elements are available to meet every application requirement, including standard hermetically sealed contacts with added reliability and safety. The actuators we use have been proven in more than 20 years of service in the world’s plants and mills. Simplicity and ease of use are stressed to improve reliability of the installation. F-Series is designed to easily retrofit many similar models and are readily available.
Hermetically Sealed Switch All Ashcroft F-Series models feature standard hermetically sealed switch contacts. We recommend hermetically sealed switch elements for improved reliability in harsh and corrosive environments. The Ashcroft F-Series is also approved for installation in Division I and II hazardous locations.
