1. Pressure switch used on pressure line/process line (pipe) to save the line/process from over pressure.
2. Level switch used on Drum/tank/vessel to see the level of the drum/tank/vessel.
3. Flow switch used the line through which fluid/liquid/air/gas is flowing, it confirms that if there is any flowing elements or not.
Input of all these switches are +24VDC and output of these are Digital Signal, these switches send a Digital Signal/Input to DCS.
My answer is right or wrong?? I am a little bit confuse...

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 =
