AST20SW Solid State Pressure Switch
Brand: American Sensor Technologies IncThe 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 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.
