Wika 9834850 Process Gauge 0-200 Psi 4.5 in Dial Npt

Product Description

The WIKA 9834850 is a process pressure gauge designed for industrial and commercial service applications requiring accurate, reliable pressure monitoring of gaseous and liquid media. The gauge features a 4.5-inch analog dial with a 0 to 200 psi single scale, a stainless steel case, and stainless steel wetted parts for corrosion resistance in demanding environments. Accuracy is rated at 0.5 percent of scale, meeting the requirements of general process instrumentation work. The acrylic lens provides clear dial visibility, and the black dial face ensures high contrast for easy reading in the field.

This gauge is suited for residential, commercial, and light industrial process systems where consistent pressure measurement of gases or liquids is required. The lower-mount, 1/2-inch NPT connection makes it compatible with standard pipe and manifold configurations commonly found in HVAC, plumbing, and process piping systems. It is typically installed by licensed plumbers, pipefitters, HVAC technicians, or instrumentation technicians during system commissioning, maintenance, or troubleshooting.

Key Features

• 0 to 200 psi single-scale range with 0.5 percent of scale accuracy
• 4.5-inch analog dial for clear, high-visibility pressure readings
• Stainless steel case and stainless steel wetted parts for corrosion resistance
• 1/2-inch NPT lower-mount connection for standard pipe thread installation
• Acrylic lens with black dial face for improved readability
• Compatible with both gaseous and liquid media

Compatibility

Designed for use with gaseous and liquid media in general process piping, HVAC, and plumbing systems utilizing standard 1/2-inch NPT lower-mount gauge connections.

Installation Notes

Installation should be performed by a qualified plumber, pipefitter, or HVAC technician. Isolate and depressurize the system completely before removing or installing any pressure gauge. Apply an appropriate thread sealant or PTFE tape to the NPT threads per the system media and pressure requirements, and do not overtighten the connection. Verify the gauge pressure range is appropriate for the system operating pressure before returning the system to service.
