The AST20SW Media Isolated Pressure Switch is a high accuracy Industrial ASIC pressure switch designed for use in a variety of applications. Applying digital compensation, this product offers top performance over a wide temperature range.

Designed for system pressures up to 20,000 psi and a standard accuracy of ±1.0%, the AST20SW utilizes Krystal Bond Technology to ensure the sensing element will measure pressure in the most extreme temperature conditions. Where other sensor technologies will freeze or boil, the AST 20SW uses a one piece stainless steel sensor to offer continuous operation. If linearity and repeatability are critical for your application, this product will exceed your expectations at an affordable price

Applications for the AST20SW Media Isolated Pressure Switch:

  • Hydraulics Controls
  • Boilers
  • Marine
  • Railways


This product can be used in the following applications:
