What is instrumentation????

As everyone knows i also have a simple definition.
Instrumentation=measure+control.
It measure the parameters which helps the process and control the process.
The basic parameters associated with process are temperature,flow level and measure.

  1. Instrumentation is also the application of measurement/control and communications technology to in-plant process control. Differs from SCADA in the distribution of intelligence (PLCs vs RTUs) and the distances involved. For example, an offshore production platform using an RTU wired to control valves and measurement transmitters and communicating with a remote Central Station computer (Master) via telemetry is classical Supervisory Control and Data Acquisition - SCADA. However, if the MTU functions were performed by the RTU, that would look like a standard DCS implementation as found in any in-plant processing unit control room.

    For practical purposes, Instrumentation refers to the field transmitters, sensors and controls which are wired in to the DCS (Central Station computer). Historically, instrumentation meant hard-wired remote control not requiring full telemetry communications because of the short distances involved. Architecturally, SCADA uses centrally located intelligence and control with the RTU having all the I/O, whereas DCS (Distributed Control Systems) features a central station computer with massive analog and discrete I/O, hard-wired to the field transmitters. Efforts to reduce the field wiring have been directed at embedding more intelligence in the field devices and implementing various bussing and networking schemes between the control room and the field. SCADA does this with radio, microwave, dedicated phone lines or a plethora of wireless "technologies". DCS does this with "Smart" transmitters and two-wire cables carrying both power and messaging (parameters or process variables and commands).

    More important to job-seekers and Instrument Technicians is the definition of Instrumentation as a previously held insider secret code word for what everyone in the top 1% of electronic technicians and high-caliber electricians could be doing, but were unaware of the job title. Good candidates for instrumentation work include Field Service Engineers/Technicians, certain Customer Service Engineers, Electronics and Engineering Technicians, copier techs, and computer mechanics with IQs over 130.

    Unfortunately, the secret is out, and any number of Junior Colleges and/or Tech Schools are turning out a flood of individuals holding 2-year "Degrees" in Instrumentation, but devoid of physics, chemistry, mechanics, metallurgy, electric motors and VFDs, digital logic, microprocessors, computer architecture, communications protocols, networking, plant operations, industry Safety Standards and Regulatory requirements. It is a fascinating and satisfying career field for those who qualify.

    In short, Instrumentation is a high-value plant asset, high margin vendor feeding trough, and serious business.

  3. Instrumentation is the branch of Engineering which deals with the measuring, controlling, maintenance of the measuring device and manipulating in manufacturing product in any industry.
