Ashcroft B Series pressure switches are designed to satisfy most switch requirements. Materials of construction have been selected for long life. A wide variety of precision switch elements are available to meet every application requirement, including hermetically sealed contacts for added reliability and safety. Special designs are available for fire safety, NACE, limit control and other more stringent requirements. Simplicity and ease of use are stressed to improve reliability of the installation.

Pressure and differential pressure switches use two different actuators depending on setpoint requirements. For setpoints between 2 and 3000 psi, the simple, rugged diaphragm-sealed piston actuator is used. This design features high reliability and choice of actuator seal materials for virtually every application. An optional welded design is also available for setpoints up to 1000 psi. Differential pressure models use a unique, dual diaphragm-sealed piston design that features very high static operating pressures and small size.

All standard models feature ±1 percent of range setpoint repeatability and a minimum of 400 percent of range proof pressures. These standard designs perform well in applications where shock and vibration could be a problem and may be used in conjunction with Ashcroft diaphragm seals in extreme services such as slurries or abrasive process fluids.

Features:

  • Single or dual independently adjustable setpoints
  • Watertight NEMA 4 or explosion proof NEMA 7 enclosures
  • Choice of switch elements for all applications
  • Choice of actuator seal
  • Setpoints adjustable from 15-100% of range
  • UL and CSA listed
