In today’s process industry, the field instruments are often calibrated out in the field. To do so, portable calibration equipment is used. Field calibration is often the best solution, but there are still various reasons why it is sometimes more convenient and effective to do calibration in a workshop.
Selecting between field calibration and workshop calibration is not a black-and-white situation. These two methods are not exclusive alternatives; instead, they complement each other.
Beamex has previously presented the arguments for doing calibration out in the field, but this paper will discuss some of the most common reasons for establishing a workshop and
doing the calibrations, or some of them, in the workshop with dedicated workshop calibration equipment.
