PR Series Hydrostatic Pressure Level Sensors The MAD4500 and MAD4510 submersible pressure sensors are approved to UL/cUL913 (CSA 157) Class I Div 1, Groups C and D for use in intrinsically safe areas with an approved barrier. For pressure ranges from 0-2.5 PSIG to 0-100 PSIG that require a wide range of media compatibility, the submersible series is an excellent solution for level monitoring in both indoor and outdoor applications. With their rugged construction and materials, these pressure sensors offer a wide range of compatibility. Typical applications include: ground water level depth measurement; earthen and concrete dams; liquid tanks; gasoline and diesel fuel tanks; irrigation; and waste water canals. Submersible hydrostatic pressure sensors; tube filter shown at left (P/N 099-00088, sold separately) Madison’s hydrostatic line of liquid leve l sensors utilizes a unique diaphragm technology and solid state design that provides high accuracy, reliability and versatility in various vessel configurations with liquid specific gravity pressure up to 100 PSIG. Should these standard models not match your application, our PR Series Specification Worksheet can be completed and submitted for engineering evaluation and quotation.
