The choice between field and laboratory calibration depends on the criticality of the control loop and the acceptable uncertainty. Field calibration saves time and allows for the verification of the entire control loop under real plant conditions, but with greater uncertainty due to environmental factors. Laboratory calibration, on the other hand, offers maximum traceability and lower uncertainty, making it ideal for standard instruments, custody transfer meters, and processes with very tight tolerances.
To make the best decision, it is crucial to have instrumentation and PLC engineers with the technical capacity to evaluate drift, tolerances, traceability, and the operational needs of each process. Their expertise allows them to determine whether on-site calibration is more suitable or if the equipment should be replaced with a temporary unit while the certification process is completed. Furthermore, a streamlined global supply of instrumentation and calibration standards helps prevent downtime and maintain operational continuity.
At Interlatam, we specialize in the strategic procurement and global supply of precision industrial instrumentation, advanced portable calibrators, and control loop components. We connect instrumentation supervisors with leading manufacturers worldwide, ensuring technical compliance, accurate data sheets, and agile logistics that minimizes plant downtime.
