The Model 20SW 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. 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
AST20SW 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.
