Sensors and instrumentation play a critical role in the operation of a sea going vessel, which means you need to be able to trust the readings they provide. Buying the best sensor is not  enough, you will need to maintain it as the readings will drift over time. To ensure sensors in operation are trustworthy, they will need adjustment from time to time, as readings can drift. Enabling the crew to perform on-site calibration it is often possible to maintain valid certificates which ensures the accuracy of equipment such as manometers, temperature sensors and pressure switches is kept.

Why Is Calibration Important to Vessels in Operation?

The zero point, stability and the acccuracy of measuring devices degrade over time, from the fresh water temperature sensors to the engine and HVAC pressure transmitters. This is typically caused by wear and tear, but can also occur from electrical or mechanical shock. Depending on the type of sensor, environment and placement, it may drift rapidly or over a longer period of time. At the end of the day you have to perform your calibrations if you want to trust your instruments on board.

What Is a Calibration?

A calibration is a comparison between a known measurement (a more accurate standard) and the measurement using your instrument.

A general rule of thumb is that the standard should be ten times more accurate than your own instrument. However, accuracy ratio of 3:1 may also be used in some cases. The objective of a calibration is simply to determine the accuracy of your measuring device.

When Should You Calibrate?

Your instrument should be calibrated:

  • According to recommendation of the manufacturer.
  • According to class demands, IOPP certification etc.
  • After any electrical or mechanical shock.
  • Periodically (annually, quarterly, monthly).

Hidden costs and risks associated with un-calibrated devices could be much higher than the cost of the calibration.
