PG23HP-P Bourdon Tube Pressure Gauge

The WIKA PG23HP-P Bourdon tube pressure gauge has been designed especially for high-pressure applications up to 6,000 bar. This makes the PG23HP-P one of the few pressure gauges available worldwide which can reliably display pressures of this order of magnitude. Typical measuring points for this pressure gauge can be found in water jet cutting, high-pressure cleaning and test bench construction.

WIKA produces and qualifies the PG23HP-P pressure gauge following the requirements of the new DIN 16001 high-pressure standard in the "S3" safety version. The safety version is made up of laminated safety glass, a solid baffle wall between measuring system and dial and a blow-out back. In the event of a failure, the operator is protected from the front side, as media or components can only be ejected via the back of the instrument.

Through the use of high-quality stainless-steel and nickel-based alloys, the WIKA PG23HP-P bourdon tube pressure gauge features excellent load cycle stability and long service life. The instrument works reliably within the specification with both static and dynamic pressure profiles.

The standard accuracy of the PG23HP-P is 1.0 %. For scale ranges up to and including 0 ... 4,000 bar, the instrument is optionally available with an improved indication accuracy of 0.6 %. The resistance to shock and vibration can be increased by the optional silicone oil case filling.
