Description
This high-quality Bourdon tube pressure gauge has been designed especially for the process industry.
The use of high-quality materials and the robust design are geared to applications in the chemical and process engineering industries.
Scale ranges of 0 … 10 to 0 … 30,000 psi [0 … 0.6 to 0 … 2,000 bar] ensure the measuring ranges required for a wide variety of applications.
WIKA manufactures and qualifies the pressure gauge in accordance with the standard ASME B40.100. As a safety function, this instrument has a solid baffle wall with blow-out back.
In the event of a failure, the operator is protected at the front side, as media or components can only be ejected via the back of the case.
The glass-fibre reinforced POCAN® case offers the necessary stability for reproducible measurements, even under aggressive ambient conditions.
With the model 233.34, the case filling in combination with a screwed-in restrictor enables use in applications with highly dynamic pressure loads and vibrations.
