Selecting the correct pressure gauge is critical for system safety and efficiency. This page covers three essential types: the fundamental tube pressure gauge (Bourdon tube mechanism), the robust industrial pressure gauge built for demanding environments, and the specialized water tank pressure gauge designed for water system monitoring. Understand their key differences and ideal applications below.
The term "tube pressure gauge" most accurately refers to the core sensing technology inside most mechanical gauges: the Bourdon tube. When pressure enters this curved, hollow tube, it straightens, moving a gear mechanism that drives the pointer. This simple, proven design is the heart of reliable pressure measurement.
Primary Use: General pressure indication where extreme durability is not the main concern.
Key Feature: Cost-effective, widely available, and suitable for non-corrosive media like air and oil.
An industrial pressure gauge is a complete instrument engineered for harsh conditions. It incorporates a tube pressure gauge mechanism (often liquid-filled for vibration resistance) into a rugged package. Features include stainless steel cases, safety glass, and enhanced seals to withstand moisture, corrosion, and physical impact common in factories and process plants.
Primary Use: Manufacturing plants, chemical processing, pump systems, and any high-vibration or corrosive environment.
Key Feature: Superior durability, often liquid-filled (glycerin), with high IP ratings for dust and moisture resistance.
A water tank pressure gauge is specifically designed for water and hydronic applications. It prioritizes corrosion resistance in its wetted parts, typically using brass or bronze connections and internals. These gauges are essential for monitoring well pressure, boiler feed systems, irrigation, and residential/commercial water pressure tanks.
Primary Use: Water wells, booster pump systems, HVAC hydronic systems, plumbing, and irrigation control.
Key Feature: Corrosion-resistant materials (brass/bronze/SS) to prevent rust and failure from continuous water contact.
| Your Application | Recommended Type | Key Reason | |
| Monitoring general air compressor output | Standard Tube Pressure Gauge | Cost-effective for clean, dry air. | |
| Measuring pressure on a chemical process line | Industrial Pressure Gauge (Stainless Steel, Liquid-Filled) | Resists corrosion and handles vibration/pulsation. | |
| Checking pressure on a home well tank | Water Tank Pressure Gauge (Brass Connection) | Built to resist water corrosion. | |
| Panel mount on factory machinery | Industrial Pressure Gauge (with appropriate connection) | Durability for the industrial environment. |
We provide precise, reliable instruments for every need. From the basic tube pressure gauge mechanism to fully ruggedized industrial pressure gauges and application-specific water tank pressure gauges, our products are manufactured under strict quality controls.
