Abstract

Pressure is one of the common parameters in Process Control whereby the periodic calibration needs to be done. Calibration is an important element in the measurement process instrumentation readings. Works on calibration will be run periodically according to a pre-set schedule depends on how critical readings in need of the processes involved. If it is critical, works calibration will be run more frequently and vice versa, if readings are in need is for monitoring purposes only. Works calibration for pressure transmitter will be executed in two ways, namely in house and field calibration. Currently for both methods, the calibration will be run manually by a service engineer. The method used for supplying air pressure to the pressure transmitter is by using manual hand pump. The reading and data from the transmitter are presented the digital manometer. The calibration report is then generated manually by the engineer. The instrument for the calibration is particularly a pressure transmitter. For the calibration, at least two transmitters will be used. One pressure transmitter must be a Master Standard Unit (MSU), and the other(s) will be Unit under Test (UUT). For this paper, the manual method is replaced by automatic control by utilising electrical and electronic equipment that is controlled by PID controller.
