Complete Calibration Process for Analog Pressure Gauges for Boilers
David Mendoza
Specialist Technician at DN Gauge
At the heart of the Arequipa industry, the precise calibration of mechanical pressure gauges is a critical task for safety and operational efficiency. This article details the meticulous process we apply in our workshop for instruments used in laundry and textile factory boilers.
Calibration Phases
Our protocol ensures each instrument recovers its original accuracy and meets the required standards.
Visual Inspection and Cleaning
Thorough review of the glass, dial, needle, and connection. Cleaning of internal components from dust and residue.
Comparison with Standard
The gauge is connected to a calibration bench with a certified standard. Ascending and descending pressure points are applied.
Adjustment and Certification
Error correction through mechanism adjustment. Issuance of a certificate with metrological traceability.
Materials and Specifications
For clear documentation, the relevant technical data of the service are presented below:
| Parameter | Typical Range | Tolerance |
|---|---|---|
| Working Pressure | 0 - 25 bar | ± 0.5% FS |
| Service Time | 24 - 48 hrs | Depends on condition |
| Post-Calibration Service Life | 12 months | Recommended |
The accuracy of a pressure gauge is not a luxury, it is an operational necessity. A stable indicator needle and a reliable reading on the dial are the first line of defense for the safety of pressure equipment in Arequipa.
