Wika Capsule Pressure Gauge Model 612.20.100, 0...600 mbar / 0...6000 mmWC, Dual Scale, 4" Dial, 1/2" NPT Lower Mount, 84272195
Technical overview
The WIKA 612.20.100 capsule pressure gauge extends the industrial low-pressure series to a 0…600 mbar / 0...6000 mmWC range for higher low-pressure applications. The copper alloy capsule measuring system is designed specifically for low over-pressures of dry, non-aggressive gases and transmits the applied pressure to a precision pointer mechanism. A 100 mm dial with 0…600 mbar primary scale and red mmWC secondary scale provides clear reading of pressure in both units. The gauge features a stainless steel case with cam-ring (bayonet) bezel, flat instrument glass window and 1/2" NPT lower Mount process connection, offering robust mechanical protection and easy installation. In accordance with EN 837-3, the instrument achieves accuracy class 1.6 and typical temperature limits of -20…+60 °C ambient and up to +100 °C medium. These characteristics make it suitable for filter monitoring, low-pressure gas distribution and level indication in process, HVAC and environmental systems.
