The transformation of instrumentation from mechanical pneumatic transmitters, controllers, and valves to electronic instruments reduced maintenance costs as electronic instruments were more dependable than mechanical instruments. This also increased efficiency and production due to their increase in accuracy. Pneumatics enjoyed some advantages, being favored in corrosive and explosive atmospheres.

As technology evolved pneumatic controllers were invented and mounted in the field that monitored the process and controlled the valves. This reduced the amount of time process operators were needed to monitor the process. Later years the actual controllers were moved to a central room and signals were sent into the control room to monitor the process and outputs signals were sent to the final control element such as a valve to adjust the process as needed.

These controllers and indicators were mounted on a wall called a control board. The operators stood in front of this board walking back and forth monitoring the process indicators. This again reduced the number and amount of time process operators were needed to walk around the units.

The most standard pneumatic signal level used during these years was psig. Whilst the controls are centralised in one place, they are still discrete and not integrated into one system.

A DCS control room where plant information and controls are displayed on computer graphics screens. The operators are seated and can view and control any part of the process from their screens, whilst retaining a plant overview. Process control of large industrial plants has evolved through many stages. Initially, control would be from panels local to the process plant.

However this required a large manpower resource to attend to these dispersed panels, and there was no overall view of the process. The next logical development was the transmission of all plant measurements to a permanently-manned central control room.

Effectively this was the centralisation of all the localised panels, with the advantages of lower manning levels and easier overview of the process.

Often the controllers were behind the control room panels, and all automatic and manual control outputs were transmitted back to plant. However, whilst providing a central control focus, this arrangement was inflexible as each control loop had its own controller hardware, and continual operator movement within the control room was required to view different parts of the process.

These could be distributed around plant, and communicate with the graphic display in the control room or rooms. The distributed control concept was born. The introduction of DCSs and SCADA allowed easy interconnection and re-configuration of plant controls such as cascaded loops and interlocks, and easy interfacing with other production computer systems. It enabled sophisticated alarm handling, introduced automatic event logging, removed the need for physical records such as chart recorders, allowed the control racks to be networked and thereby located locally to plant to reduce cabling runs, and provided high level overviews of plant status and production levels.

Applications[ edit ] In some cases the sensor is a very minor element of the mechanism. Under most circumstances neither would be called instrumentation, but when used to measure the elapsed time of a race and to document the winner at the finish line, both would be called instrumentation.

Household[ edit ] A very simple example of an instrumentation system is a mechanical thermostat , used to control a household furnace and thus to control room temperature. A typical unit senses temperature with a bi-metallic strip. It displays temperature by a needle on the free end of the strip.

It activates the furnace by a mercury switch. As the switch is rotated by the strip, the mercury makes physical and thus electrical contact between electrodes. Another example of an instrumentation system is a home security system.

Communication is an inherent part of the design. Kitchen appliances use sensors for control. A refrigerator maintains a constant temperature by measuring the internal temperature. A microwave oven sometimes cooks via a heat-sense-heat-sense cycle until sensing done. An automatic ice machine makes ice until a limit switch is thrown. Pop-up bread toasters can operate by time or by heat measurements. Some ovens use a temperature probe to cook until a target internal food temperature is reached.
