Description

The WIKA 612.20.100 capsule pressure gauge, belongs to the industrial low-pressure series designed for precise measurement of small positive pressures of dry, non-aggressive gases. A copper alloy capsule measuring system converts the low process pressure into a proportional movement, which is indicated on the large 100 mm dial with 0…250 mbar primary scale and red mmWC secondary scale. The stainless steel case with cam-ring (bayonet) bezel and flat instrument glass window provides robust protection for demanding plant environments. Design and performance follow EN 837-3, with an accuracy of class 1.6 and typical permissible temperature range from -20…+60 °C ambient and up to +100 °C medium. The 1/2" NPT lower Mount process connection simplifies installation on manifolds, impulse lines or panels, making this capsule gauge ideal for ventilation, filter monitoring, level indication using mmWC units and other low-pressure pneumatic applications.
