electrical contacts

Electrical contacts - Download BrochureThese are devices that can open or close an electric circuit. They are constructed using movable contacts in air that can be positioned on 270° of the scale.
They are usually made in silver, for severe working conditions we recommend platinum, and for use under vibration they can be equipped with magnetic blocks.

Electrical contacts can be applied to all manometers, hydrometers, and vacuum guages from DN100 to DN250.
