Q & A
Bourdon Tube Pressure Gauge Model 233.55 Q & A
+ What are the key features and specifications of the WIKA 233.55 Bourdon tube pressure gauge?
The WIKA 233.55 Bourdon tube pressure gauge is an industrial, panel-builder gauge designed for reliable pressure measurement in demanding process environments. It features an all-stainless steel construction with 316 stainless steel wetted parts, making it suitable for corrosive gas and liquid applications. The gauge is glycerine-filled to dampen vibration and pressure pulsation, helping ensure stable readings and longer service life. It typically includes a 2?-inch dial for clear visibility, a lower back mount connection for panel installations, and compliance with ASME B40.100 standards for accuracy and performance, making it a trusted choice for industrial automation, OEM panels, and process control systems.
+ What pressure range and accuracy should I choose for my application?
When selecting a pressure range for the WIKA 233.55 gauge, it is recommended to choose a range where normal operating pressure falls near the middle of the scale, rather than at the extreme high end. This approach improves accuracy and extends the life of the gauge. For example, if a system typically operates around 500 psi, a 1,000 psi gauge provides optimal readability and performance. The 233.55 series offers a wide range of pressure options, from vacuum and compound ranges to high-pressure applications, depending on the specific model. The gauge meets ASME B40.100 accuracy requirements, which is generally suitable for most industrial process monitoring applications.
+ What process connection type and mounting configuration does the WIKA 233.55 use?
The WIKA 233.55 pressure gauge is commonly supplied with a lower back mount configuration, which is ideal for panel-mounted applications in control cabinets and instrumentation panels. Standard process connections typically include 1/4-inch NPT threads, which are widely used in U.S. industrial piping systems. Choosing the correct connection size and thread type ensures proper installation without the need for adapters, helping maintain system integrity and measurement accuracy. Customers should confirm mounting orientation and thread specifications to match their existing piping or panel layout.
+ Is the WIKA 233.55 suitable for corrosive or harsh industrial environments?
Yes, the WIKA 233.55 is specifically designed for use in corrosive and harsh industrial environments. Its stainless steel case and 316 stainless steel wetted components provide strong resistance to corrosion from chemicals, moisture, and aggressive process media. The glycerine-filled case reduces the effects of vibration and pressure spikes, making the gauge well-suited for applications with fluctuating pressures or mechanical shock. These features make the 233.55 a dependable option for chemical processing, water and wastewater systems, oil and gas operations, and general industrial process control.
+ Can the WIKA 233.55 pressure gauge be installed in different orientations?
The WIKA 233.55 pressure gauge is designed to be installed in a standard upright orientation for optimal readability and performance, particularly in panel-mounted installations. While the gauge can physically operate in other orientations, non-standard mounting may reduce readability or allow contaminants to collect in the case over time. For best results, the gauge should be installed so the dial is easy to view and the process connection is properly aligned with the piping. If an application requires a different orientation, mounting accessories, or alternative configurations may be considered.
