Answer / oscar b. ano-os jr.

instrumentation is the science and art of using instruments
in a control system for the purpose of monitoring and
control of the process variables such as flow, temperature,
level, pressure and so forth...

Answer / ulaganathan

the basic of instrumentation deals with only
measurement ,control of operation,handling the equipment

Answer / asish kumar kar

Instrumentation is to measure, control and logging
(recording) of process variables like temp, flow, pressure
etc.

Answer / nagarajan singapore

Instrumentation is nothing but measuring and controlling
the process variable( temperature ,pressure ,flow ,level
ets)in the closed or open loop condition .maintain the
system realiability and accuracy for the process,

Q1: Consider part of a control loop, which excludes the transmitter, consisting of a process, a controller and a control valve which may be represented by two dead times of 0.5 min each and three exponential lags of 0.8 min., 1.0 min. and 1.5 min. respectively. We wish to express this system as an overall first order plus dead time (FOPLD) model ie gain, time constant and process dead time. (We will see later that this is often done, to simplify controller tuning). For this exercise, gain is considered to be 1.0. (A) If the transmitter is a flow transmitter whose behaviour can be described by a dead time of 0.2 min. and an exponential lag of 0.5 min. in terms of the overall dead time and overall first order lag how can the system behaviour be approximated ? Overall dead time = Overall time constant = (B) If the transmitter is a temperature transmitter with a temperature sensor in a protecting well whose behaviour can be described by a dead time of 0.7 min. and an exponential lag of 15 min. how can the overall system behaviour be approximated now? Overall dead time = Overall time constant =
