Madison Company's MAD4500/4510 and MAD4520 series of Submersible Pressure Transducers now feature a standard ½” male NPT conduit connection. Thanks to this improvement – made in response to ongoing customer feedback – users can more easily attach junction boxes and flexible conduit to the rear of the units. Madison’s Hydrostatic Pressure Level 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. The MAD4500 and MAD4510, ruggedly constructed from high-strength stainless steel, are suitable for harsh environments, both indoors and outdoors. They are compatible with a wide range of liquids and are ideal for such applications as ground water level depth measurement; earthen and concrete dams; liquid tanks; gasoline and diesel fuel tanks; irrigation; and wastewater canals.
