ProtEX™, ProtEX-MAX™, and ExSense™ Meters for Precision Digital Corp.   Industrial Design Mechanical Engineering Prototype Production Support   Objective Use industrial design as a competitive advantage to distinguish their products in an industrial market. Fully engineer each product for multiple internal components and different materials including aluminum, stainless steel, and plastic.   Results The 12 year collaboration between Stream and Precision Digital Corp. has produced three new families of products. The ProtEX™ and ProtEX-MAX™ series are meters for measuring temperature, pressure, and water flow in harsh industrial environments. The ExSense™ series is a smart temperature transmitter system. They are explosion proof die-cast aluminum NEMA 4X enclosures.   All three product lines are easy to use, service, and install. The deep finger grooves make it simple to unscrew the cap by hand. A large screwdriver can also be engaged in the notches to twist off the tight seal. Built-in mounting ears allow for very flexible mounting options including wall or pipe without the need for an external bracket. The design looks good in any orientation.   These products have strengthened Precision Digital Corp's leadership position in the industrial meter market. The visual appeal of these meters is so strong in this market, an OEM sales channel has been developed to sell the enclosures at ExDirect.
