Often, there is a misinterpretation of the meanings of “calibration” and “maintenance.”
Maintenance activities focus on CHANGEABLE effects, for example:
- Cleaning a dirty sensor
Calibration, on the other hand, will compensate for UNCHANGEABLE effects. These are:
- Aging of the pH glass, usually caused by chemicals in the process or high temperatures
- Poisoning or depletion of the reference chamber
Calibration itself will not extend the life of a sensor, but a sensor that is not calibrated correctly can cause unreliable measurements. In some cases, that even results in unnecessary replacements. Do not underestimate the importance of calibration – review the do’s and don’ts of pH calibration.

With products, solutions, and industry expertise, Yokogawa understands your market and production needs and will work with you to provide a reliable, and cost-effective solution through the lifecycle of your plant.
Reducing emissions for home grown energy.
Chemical plants rely on continuous and batch production processes, each posing different requirements for a control system. A continuous process calls for a robust and stable control system that will not fail and cause the shutdown of a production line, whereas the emphasis with a batch process is on having a control system that allows great flexibility in making adjustments to formulas, procedures, and the like. Both kinds of systems need to be managed in available quality history of product, and to be able to execute non-routine operations. With its extensive product portfolio, experienced systems engineers, and global sales and service network, Yokogawa has a solution for every plant process.
