The WIKA 232.53 and 233.53 are bourdon tube style process gauges. With pressure ranges from vacuum to 15,000 psi the 232.53, a dry gauge, and 233.53, with a liquid filled case, are ideal for many applications within the process industry such as chemical/petrochemical, power stations, mining, on and offshore, environmental technology, mechanical engineering and plant construction. Both gauges are suitable for corrosive environments and gaseous or liquid media that will not obstruct the pressure system. The liquid-filled option, 232.53, is also suited for applications with high dynamic pressure pulsations or vibration.
The WIKA 232.53 and 233.53 pressure gauges are designed to ASME B40.100 and EN 837-1 standards. Each gauge features all stainless steel construction that provides weather tight NEMA 4X / IP65 protection. Both models are available with 2", 2-1/2" or 4" dials. A variety or process connection and connection locations are available.
