Wika 9834015 Process Pressure Gauge 0-100 Psi 4.5 in Dial

Product Description

The WIKA 9834015 is an analog process pressure gauge rated from 0 to 100 psi, designed for continuous monitoring of gaseous and liquid systems in demanding trade and industrial applications. It features a 4.5-inch dial for easy readability at a distance, a thermoplastic case for corrosion resistance, and stainless steel wetted parts that hold up against aggressive media. Accuracy is rated at 0.5 percent of scale, meeting the precision requirements of process monitoring, mechanical systems, and fluid handling installations. A lower-mount, 0.5-inch NPT male connection provides straightforward inline installation on standard piping configurations.

This gauge is suited for residential and commercial mechanical systems where reliable pressure indication is required on liquid or gas lines. Typical applications include water supply, chilled water loops, compressed air systems, chemical feed lines, and general process piping. The lower-mount configuration is commonly used where the gauge is mounted directly to a tee, valve, or manifold at the bottom of the gauge body. The large 4.5-inch dial face improves readability in equipment rooms, mechanical closets, and on panel boards.

Key Features

• 0 to 100 psi single-scale analog pressure range
• 4.5-inch dial diameter for high-visibility readings
• Stainless steel wetted parts for compatibility with aggressive liquids and gases
• Thermoplastic case with black finish and acrylic lens
• 0.5 percent of scale accuracy for precise process monitoring
• Lower-mount 0.5-inch NPT connection fits standard pipe fittings

Compatibility

Designed as an OEM-style replacement or new-installation process gauge for gaseous and liquid pressure monitoring applications using standard 0.5-inch NPT lower-mount connections.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified HVAC technician. Depressurize and isolate the system completely before connecting or removing any gauge. Apply thread sealant or PTFE tape to NPT threads in accordance with applicable IPC and IFGC guidelines. Do not over-tighten the connection at the gauge port, as thermoplastic gauge bodies can be damaged by excessive torque.
