AST4500 & AST4510

Class 1 Div 1, Groups C and D with Approved Barrier

ubmersible Stainless Steel Media Isolated Pressure Senso

Overview

The AST4500 and AST4510 submersible pressure sensors are approved to UL/cUL913 (CSA 157) Class 1 Div 1, Groups C and D for use in intrinsically safe areas with an approved barrier. For pressure ranges from 0-2.5 to 0-100 PSI that require a wide range of media compatibility, the submersible series is an excellent solution to level monitoring for indoor and outdoor applications.
