Overview

Applying digital compensation, this expolsion proof pressure switch offers advanced performance over a wide temperature range. The sensing element will measure pressure in the most extreme temperature conditions. Where other sensor technologies will freeze or boil, the AST46SW 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.
