Quick Selection Guide

Basic Opposed Piston Differential Pressure Detectors with standard wetted parts are normally

suitable for air, oil, water and non-corrosive process applications in hazardous locations and hostile

environments. Refer to the Quick Selection Guide section on page 4. Corrosive service and particular

customer requirements may require optional components. Refer to How to Order below to build a

customized model number or the dedicated page to locate optional components, such as: detecting

elements, diaphragm systems, pressure ports and accessories. Each position in the model number,

except Accessories, must have a designator.
