ブルドン管デジタル二重スケール

Overview
Category of instruments for measurement, control and adjustment of vacuum and pressure including conversion tables, gauges, switches (pneumatic, electromechanical, digital, IO-Link), regulators, adjustment valves, accessories and sealing kits.

Vacuum and pressure unit conversion table
Vacuum and pressure unit conversion tables and pressure measurement unit conversion factors (absolute values).

Vacuum and pressure gauges
The measurement method is based on the Bourdon spring principle. Section tubes in special copper alloy welded to the threaded pin form a single body. Movement of the free end is amplified by a lever and transmitted to the pointer. Housings and materials vary by model; face and index visible through protective disc. Available with radial or coaxial connectors, built-in or external flange, dry or glycerine filled. Except Ø 40 mm, other models have a double scale dial. All models comply with applicable EU safety and measurement standards.

Vacuum adjustment valves
Valves that, when reaching a pre-calibrated vacuum degree, introduce atmospheric air into the circuit to prevent increase and keep vacuum constant. Used as regulators on circuits with a single vacuum pump or as safety valves on tanks or vacuum cup systems. Vacuum level adjusted by rotating knurled bush; fine thread enables accurate calibration. Operating temperature range -20 °C to +200 °C.

Vacuum regulators
Devices that maintain vacuum constant at preset secondary vacuum regardless of source flow and primary vacuum fluctuations. Operate by membrane-piston using pressure differential between secondary vacuum and atmosphere. Unlike adjustment valves, regulators do not release air into circuit, allowing multiple grip points at different vacuum degrees from a single source. Vacuum level adjusted via knurled thumb screw.
Technical features

Vacuum regulators with pneumatic adjustment
Adjustment performed by pneumatic cylinder compressed air supply rather than manual screw. Supply pressure ranges and adjustable working pressure depend on model series. Useful when remote pneumatic control of vacuum setpoint is required.

• Adjustable working pressure examples: from 800 to 1 mbar abs or 980 to 1 mbar abs depending on model
• Flow rates and temperature ranges similar to manual regulators
