Bourdon Tube Pressure Gauge Models 233.53 and 232.53 from WIKA

WIKA Bourdon Tube Pressure Gauge Models 233.53 and 232.53The WIKA 232.53 and 233.53 Bourdon Tube Pressure Gauges are mechanical pressure instruments designed for standardized industrial pressure measurement. Manufactured by WIKA, these models are part of the company’s stainless steel gauge portfolio and are intended to provide consistent and reliable pressure indication across a wide range of operating conditions.

The 232.53 is a dry case pressure gauge, while the 233.53 is a liquid-filled version designed to stabilize pointer movement under dynamic pressure conditions. Both models are produced using stainless steel materials and comply with ASME B40.100 and EN 837-1 standards. The series is offered in multiple pressure ranges and dial sizes, allowing users to select configurations that align with system requirements and installation preferences.

Bourdon Tube Pressure Gauge Models 233.53 and 232.53 Q & A

+ What is the difference between the WIKA 232.53 and 233.53 pressure gauge models?

The WIKA 232.53 is a dry case stainless steel Bourdon tube pressure gauge, ideal for general industrial pressure measurement. The 233.53 is a liquid-filled version (typically with glycerin or silicone) that dampens vibration and pulsation, protecting the movement for more accurate readings in dynamic environments.

Dry gauge (232.53) – standard process use

Liquid-filled gauge (233.53) – vibration or pulsating applications

 
+ What pressure ranges and sizes are available for these WIKA stainless steel gauges?
The 232.53 and 233.53 series offer a wide range of pressure scales, from vacuum/compound low ranges up to high pressure (to 15,000 psi / 1,000 bar), depending on the configuration. They are available in 2″, 2?″, and 4″ dial sizes for easy viewing in many installations.
+ What environments and media are suitable for the WIKA 232.53/233.53 gauges?
These gauges are built for industrial environments and corrosive service thanks to 316 stainless steel wetted parts and stainless housings. They work with gaseous or liquid media that won’t clog the pressure system and support applications in the chemical, petrochemical, power, mining, offshore, and process industries. Ideal use cases are corrosive fluids, high dynamic pressure pulsations (liquid-filled), and harsh industrial process systems.
 
+ What mounting and connection options do these WIKA gauges support?
The WIKA 232.53/233.53 gauges offer 1/8″, 1/4″, or 1/2″ NPT connections in either lower or back mount configurations, making them compatible with pipe, panel, or manifold installations. The flexible mounting also supports field adaptation in tight or complex setups.  
 
 
+ How accurate and durable are WIKA’s 232.53 & 233.53 pressure gauges?
These pressure gauges meet ASME B40.100 and EN 837-1 standards for accuracy and reliability. Smaller dials (2″ / 2?″) typically offer ±2.5 % of span, while larger 4″ dials offer ±1 % of span accuracy. All-stainless steel construction ensures excellent shock resistance and load-cycle stability in demanding industrial environments.
