Selecting the right Accutek pressure gauge isn’t just about picking a dial size or PSI number. It’s about ensuring your system runs safely, efficiently, and with long-term accuracy. In industrial environments, the wrong gauge can lead to vibration failures, inaccurate readings, leaks, and unnecessary downtime.
Why Gauge Selection Matters More Than You Think
Pressure gauges are often one of the smallest components in a system, but they are essential. They:
- Verify system pressure
- Protect equipment
- Help diagnose operational issues
- Indicate dangerous conditions
- Support compliance with safety regulations
A poorly selected gauge leads to:
- Needle flutter
- Premature seal failure
- Inaccurate readings under vibration
- Fogged lenses
- Burst failures under system spikes
- Media incompatibility (corrosion, chemical attack)
Accutek’s pressure gauge lineup is designed to eliminate these problems, but only if the gauge matches your environment and application.
Step 1: Choose the Right Gauge Type
Accutek offers several gauge families, each engineered for specific conditions. Understanding their strengths will guide your selection.
1. Dry Gauges — Best for Stable, Low-Vibration Environments
Dry gauges are the most economical and commonly used across:
- Air compressors
- General pneumatic systems
- Water pressure setups
- Light industrial machinery
Why choose a dry gauge:
- Cost-effective
- Reliable for steady-state applications
- No liquid maintenance required
When not to use a dry gauge:
- High vibration
- Pulsation
- Extreme cold
- Rapid pressure fluctuations
In these environments, you need a dampened option.
2. Liquid-Filled Gauges — Best for Vibration, Shock, and Outdoor Use
Accutek liquid-filled gauges use glycerin to stabilize the needle and protect internal components.
Ideal for:
- Pumps and compressors
- Hydraulic equipment
- Process lines
- Machinery with constant vibration
Key advantages:
- Reduces pointer vibration for easier reading
- Extends gauge life
- Protects against pulsation
- Prevents fogging in humid environments
Accutek also offers low-temperature liquid-filled gauges, rated as low as –76°F (–60°C)—perfect for cold storage, refrigeration, and northern climates.
3. The Equalizer™ Gauge — A Liquid-Filled Gauge Without the Liquid
The Accutek Equalizer™ Pressure Gauge mimics the performance of a liquid-filled gauge without the drawbacks.
Why Equalizer™ is unique:
- No leaking glycerin
- No fluid discoloration
- No fogging
- No viscosity issues in cold environments
- No need for filling or refilling
Perfect for:
- Vibration-heavy applications
- Outdoor installations
- Environments where liquid gauges can freeze
- Chemical, petrochemical, and process industries
If you want long-term stability with zero maintenance, this is the top choice.
4. Specialty Gauges — For Unique Industrial Needs
Vacuum Gauges
Measure negative pressure (30–0 inHg). Perfect for suction systems and vacuum pumps.
Digital Gauges
Highly accurate, unit-selectable, ideal for diagnostics and calibration.
Tell-Tale Gauges
Capture maximum pressure reached; excellent for troubleshooting pressure drops or peak loads.
Tridicators (Pressure + Temperature)
Used in boilers, hydronic heating systems, and hot water tanks.
Choosing a specialty gauge depends entirely on whether your system requires additional diagnostic insight beyond standard pressure readings.
Step 2: Select the Mounting Configuration
Installation determines readability and safety. Accutek pressure gauges come in multiple mount types:
Bottom Mount
- Easy to install
- Ideal for vertical piping
- Common in HVAC and water systems
Center Back Mount
- Used on control panels
- Faces forward for easy viewing
- Often paired with brackets
Stem Mount
Best for compact or specialty installations.
Step 3: Consider the Temperature Rating
Dry Gauges: –40°F to +140°F
Best for indoor or temperature-stable environments.
Standard Liquid-Filled: –4°F to +150°F
Ideal for mechanical rooms and outdoor use.
Low-Temperature Liquid-Filled: Down to –76°F
- Cold storage
- Refrigeration systems
- Northern outdoor installations
Equalizer™ Gauge: –58°F to +200°F
Best when liquid-filled gauges may thicken or freeze.
Step 4: Match the Pressure Range to the System
- 0–15 PSI
- 0–30 / 0–60 / 0–100 / 0–160 PSI
- Up to 10,000+ PSI
Best practice: operate between 25–75% of full scale.
Step 5: Identify Your Media Compatibility
Brass Internals
- Air, water, light oils
- Most economical
- Common HVAC use
316 Stainless Steel Internals
- Corrosive chemicals
- Food & beverage
- Process industries
Media incompatibility is one of the most common causes of gauge failure.
Step 6: Handle Vibration, Pulsation & System Shock
| Environment | Best Gauge | Why |
|---|---|---|
| Pumps & compressors | Liquid-filled | Dampens vibration |
| Outdoor equipment | Equalizer™ | No freezing or leakage |
| Hydraulics | SS Liquid-filled | High durability |
Step 7: Choose the Right Dial Size
- 1.5–2" → Tight spaces
- 2.5" → Most common industrial size
- 4" → High-visibility applications
Step 8: Diagnostic Features
Tell-Tale Needle
- Captures peak pressure
- Identifies pressure loss
Digital Gauges
- Multi-unit display
- Backlit
- Peak hold
Tridicators
- Boilers
- Hydronic systems
- Hot water tanks
