Wika 233.50 Bourdon Tube Pressure Gauge Stainless Steel
The model 233.50 with liquid-filled case is suitable for highdynamic pressure loads and vibrations.
Description
This high-quality Bourdon tube pressure gauge has beendesigned especially for the process industry.
The use of high-guality stainless steel materials and therobust design are geared to applications in the chemicaland process engineering industries.Thus the instrument issuitable for liquid and gaseous media, also in aggressiveenvironments.
Scale ranges of 0 … 0.6 to 0 … 1,600 bar [0 … 10 to0 …20.000 psil ensure the measuring ranges required for awide variety of applications.
WlKA manufactures and qualifies the pressure gaugcin accordance with the standards EN 837-1 andASME B40,100.As a safety function, this instrument has ablow-out device with blow-out plug on the back of the case. Inthe event of a failure,overpressure can escape there.
The model 233.50 with liquid-filled case is suitable for highdynamic pressure loads and vibrations.
The QR code on the dial allows instrument-specific informa.tion such as the serial number, the order number. certificatesand other product data to be retrieved from the internet easilyand in the long term.
