Instrumentation And Control System

Control Systems serve the crucial purpose of ensuring that the requisite output is rendered by mechanical, optical as well as electronic systems. Similarly, Instrumentation Systems play an essential role in providing support to critical process systems through its range of engineered hardware and software controls.

 Annunciators are panels which may or may not have lights placed in a consecutive pattern. These panels used as devices for electrical signalling which is indicative of the current status of the entire equipment or system. Annunciators are versatile in their usage because of which they are deployed in aircrafts, industrial processes, construction or installation. Equipped with a warning light or an audible signal, the annunciator works as a whistle-blower to alert the operating personnel about any functional anomalies.

The Instrumentation and Control system comprises several subsystems with their electrical and electronic equipment:

• sensors which supply measured data – pressure, temperature of the primary circuit, the liquid level … - and transform physical data into electrical signals, 
• programmable controllers to process those signals, and drive the actuators. These systems, based on a number of input data, provide automatic orders to ensure that process parameters are kept within the range on which the safety is based or to trigger protection actions such as reactor trip.
• monitoring and control means for use by the plant operators (control panels, alarms ...). In the control room, are centralized sufficient and relevant information and remote control means to monitor the plants.
