Dual-scale pressure gauge 090315

threadedflangebuilt-in

Description
The measurement element is based on the Bourdon tube principle. A section tube in a special copper alloy is welded to the gauge threaded pin to form a single body; the closed free end deforms as vacuum or pressure changes. The movement of the free end is amplified by a linkage lever and transmitted to the pointer for reading.

The mechanism is enclosed in a case made from materials selected according to the model and fixed to a threaded connection for system mounting. The dial and pointer are visible through a clear plastic protective disc. Available versions include radial or coaxial connections, built-in or external flange, and dry or glycerine-filled variants. Except for Ø 40 mm vacuum gauges, all models feature a dual-scale dial. All gauges are manufactured in compliance with current EU safety standards and measurement units.
