Description
Product Overview
The Dixon Wilkerson Differential Pressure Indicator is engineered for precise pressure monitoring in demanding industrial environments. Constructed from high‑grade metal, the housing resists corrosion, impact, and temperature extremes, ensuring a long service life even in harsh conditions. The indicator window utilizes a dual‑color liquid system that transitions smoothly from green to red as pressure differentials develop, providing an instantly recognizable visual cue without the need for auxiliary instrumentation.
Designed to accommodate standard M16, M26, and M30 pipe threads, the unit integrates seamlessly into existing piping networks. The compact form factor (6.14 x 4.8 x 1.34 inches) allows installation in confined spaces, while the lightweight design (1.28 ounces) simplifies handling and mounting. The product carries the reputable Dixon brand name, known for reliability and accuracy in pressure measurement devices.
Technical specifications include a pressure range suitable for most HVAC, refrigeration, and process‑control applications, with a clear indication threshold calibrated to typical system requirements. The indicator is calibrated at the factory and requires no user‑adjustable settings, reducing installation time and potential for error.
Packaging is optimized for protection during shipping, featuring a sturdy cardboard box with molded inserts that secure the gauge and protect the delicate indicator window. The product is listed under the Industrial & Scientific category, specifically within Differential Pressure Gauges, reflecting its specialized function.
Customer feedback highlights a 5‑star rating based on six reviews, emphasizing the gauge’s reliability, ease of reading, and durability. The product has maintained a strong sales rank, indicating consistent demand among professionals seeking a trustworthy pressure loss indicator.

Usage
This differential pressure indicator excels in applications where rapid detection of pressure loss is critical. Typical use cases include monitoring air handling units, refrigeration condensers, and filtration systems where a drop in pressure can signal blockages, leaks, or equipment failure. By providing an immediate visual alert, maintenance personnel can respond promptly, minimizing downtime and preventing costly damage.
Installation is straightforward for technicians familiar with standard pipe fittings. The gauge can be mounted on vertical or horizontal runs, and its clear window remains legible from a distance, making it ideal for panel installations or remote monitoring stations. The indicator’s color‑change mechanism does not require power, allowing deployment in locations without electrical access.
Target audiences include HVAC engineers, refrigeration specialists, plant maintenance teams, and quality‑control inspectors. The device is also suitable for educational laboratories where students learn about pressure differentials and system diagnostics.
Because the indicator does not rely on electronic components, it operates reliably in environments with electromagnetic interference, high humidity, or extreme temperature fluctuations. This robustness makes it a preferred choice for outdoor installations, such as ventilation shafts and industrial exhaust systems.

FAQ
What pressure range does the indicator cover?
The gauge is calibrated for typical HVAC and refrigeration differentials, generally spanning from 0 to 5 psi. Exact range details are provided in the product datasheet.
Can the indicator be used with non‑metallic piping?
Yes, as long as the pipe thread size matches M16, M26, or M30, the gauge can be installed on plastic, copper, or stainless‑steel fittings without affecting performance.
Is calibration required after installation?
No additional calibration is needed. The indicator is factory‑calibrated and ready for immediate use, reducing setup time and potential errors.
How does the color‑change mechanism work?
The internal liquid contains a dye that reacts to pressure differentials. When the pressure drops below the set threshold, the dye shifts from green to red, providing a clear visual signal.
What warranty does Dixon provide?
Dixon offers a one‑year limited warranty covering manufacturing defects. Customers can contact our support team for warranty claims or technical assistance.
