In a system, especially in the PLTU 2 AdipalaCilacap of Central Java, instrumentation and control system is required in order to generate energy to run optimally and produce energy according to the targets set. Instrumentation and control systems in Central Java PLTU 2 also contribute to maintaining the safety and reliability of the system. The use of instrumentation allows all process variables are controlled automatically. Indication of measurement results using a local featured in gauge or sent to the control center (control room). The benefit of sending a measured quantities to a control center is the ability to control and correct these quantities automatically via a controller, according the desired set point. Also, when the abnormal condition occurs, an alarm will appear which can trigger protection to shut down the plant safely. At PLTU 2 Central Java using equipment called a differential pressure transmitter, the equipment used to measure the speed of the water and the level of a tank in PLTU 2 Central Java. Differential pressure transmitter needs to bean optimal maintenance activities in order to prevent damage, improve equipment reliability and increase lifetime of the equipment.
