Gauge Repair
Haygor evaluates and repairs pressure, vacuum, compound, process, test, sanitary, and other mechanical gauges used throughout industrial operations. Each unit is reviewed by manufacturer, model, range, connection, condition, and application before a service path is recommended.
Restore the instrument already matched to the installation.
A gauge may be a small component in a larger system, but its range, dial size, scale, mounting, process connection, wetted materials, and operating environment can be specific to that application. When readings become inaccurate, unstable, unreadable, or unresponsive, a direct replacement is not automatically the lowest-risk answer.
Haygor begins with an equipment evaluation to determine whether repair, remanufacture, calibration, or replacement review is the most practical path. General pressure and process gauges are covered here; instruments designed specifically to measure pressure difference are addressed through Haygor’s Differential Gauge Repair service.
Gauge Types and Configurations Evaluated
Serviceability depends on the exact design, condition, available components, process requirements, and requested scope. Send the manufacturer, model, range, and clear photographs so the correct repair path can be reviewed.
- Industrial pressure gauges
- Vacuum gauges
- Compound pressure and vacuum gauges
- Process and safety-pattern gauges
- Test and inspection gauges
- Sanitary and hygienic gauges
- Liquid-filled gauges
- Panel, surface, and stem-mounted gauges
- Receiver and pressure-indicating gauges
- Selected liquid-level and flow-rate indicators
- Legacy and discontinued mechanical gauges
- Gauge and diaphragm-seal assemblies
What Gauge Repair May Include
The authorized scope is based on the incoming inspection and the instrument’s design. Not every operation applies to every gauge.
Mechanical Restoration
- Incoming condition inspection and fault diagnosis
- Movement, linkage, pointer, dial, and zero-position review
- Case, window, gasket, mounting, and connection evaluation
- Cleaning and corrosion assessment
- Replacement of serviceable components when available
- Reassembly, refinishing, and functional checks as applicable
Testing and Calibration Support
- Pressure or vacuum function testing as applicable
- Zero, span, pointer, and range adjustments where the design permits
- Calibration at agreed test points across the required range
- Accuracy verification against the requested specification
- NIST-traceable calibration support where requested and applicable
- Service and calibration documentation matched to the agreed scope
Repair, Remanufacture, or Replace?
The right answer starts with the gauge, the installation, and the process—not a catalog assumption.
Repair may be practical when:
- The existing gauge already matches the required range, mounting, connection, and scale
- A direct replacement is obsolete, unavailable, or difficult to source
- The instrument has a custom dial, scale, case, or mounting arrangement
- The condition allows the required function and accuracy to be restored
- Repair can reduce installation changes, rework, or process disruption
Replacement review may be better when:
- Damage to the pressure boundary or sensing element makes repair impractical
- The required range, media, material, accuracy, or application has changed
- Critical parts are unavailable or the repair risk is not justified
- The installation now requires a different gauge design or protection method
- A modern replacement provides a more appropriate long-term service path
A Controlled Gauge Service Process
Work proceeds against an agreed scope so the repair decision, authorized work, performance checks, and return documentation remain clear.
Inspect & Diagnose
Review the gauge, visible condition, failure symptoms, nameplate data, range, connection, and application.
Define the Scope
Outline the recommended repair or remanufacture work, known limitations, pricing, and expected timing.
Repair or Remanufacture
Complete the authorized mechanical restoration, component replacement, adjustment, and refinishing work.
Test & Calibrate
Verify operation and performance against the agreed range, test points, accuracy, and documentation requirements.
Return & Support
Package the gauge for return, provide applicable service records, and support return-to-service questions.
Start With the Nameplate
Better equipment information produces a more accurate evaluation. Send what is available; Haygor can identify missing details during review.
- Manufacturer, model, and serial number
- Dial size, case style, and mounting arrangement
- Range, engineering units, and accuracy requirement
- Process connection and wetted materials, if known
- Process media, operating pressure, and temperature
- Clear photos, failure symptoms, quantity, and required timing
Send the Gauge Details for Evaluation.
Provide the nameplate, range, connection, mounting, service conditions, photographs, and failure symptoms. Haygor will review whether the practical next step is repair, remanufacture, calibration, filled-system evaluation, or replacement review.
