Application The WIKA Dampened Movement is intended for gauges installed in vibration and pressure pulsation applications. It meets all specifications that are found on standard Process Gauges of equivalent material. For the maximum life cycle, WIKA recommends a liquid filled gauge to protect against vibration and wear. However, certain applications or regulations, may require the Dampened Movement system. Typical of these applications are industries with strict environmental controls or maintenance philosophies that have restricted the use of Liquid Filling. The Dampened Movement option is a solution for these installations.
Operating Principle The WIKA Dampened Movement uses a unique capsule that is connected to the end of the pointer shaft movement. The capsule has an inner drum that rotates inside the capsule housing on a thin film of silicone grease. The thin film of grease provides the correct dampening to eliminate pointer vibration. The capsule housing keeps the dirt out and the silicone grease in for trouble free movement.
