Answer / s.kalpana archana

Instrumentation is about measuring,controlling and processing the various parameters such as pressure,temperature,flow,level,etc.....

Answer / afsar mumtaz

to measure process variables like ,temp,pressure,flow,level and distance.

Answer / afsar mumtaz

study of instruments is called instrumentation and
measurement of process variable.

Answer / mhax papio

Instrumentation is arrangement of two or more instrument
connected together to perform a unified task.And a Control
loop is the simpliest form of instrumentation system

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 =
