The Model 46SW is a high accuracy Explosion-proof Pressure Switch, designed for use in
a variety of applications. Applying digital compensation, this product offers top performance
over a wide temperature range. Utilizing Krystal Bond Technology™, 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.
