WIKA F-20 and F-21 General Purpose Pressure Transmitters with NEMA 4X Integral Junction Boxes

WIKA'S F-20 and F-21 are designed for use in corrosive environments. The NEMA 4X/IP67 stainless steel case and water-tight smooth exterior surface makes them great for use in the food service industry where sanitary wash-down procedures are required. The integral junction box cover unscrews for easy access to the internal spring clip terminal block.

The model F-20 has a threaded process connection while the model F-21 features a flush diaphragm — better suited for measuring viscous fluids or media containing solids that can clog the F-20's NPT connection.
