In split range control, we will control 2 outputs with time
interval. Eg :(with 4-20 ma signal, for 4-12 ma we are
operating one control instrument like valve & for 12-20ma we
are operating other control instrumet (other valve). If we
get a signal of 15ma to first instrument (Valve 1), what
will happened to the first valve, and if we get signal above
20 ma to 2 valve what will happened ?

Answer Posted / pramod suwalka

1. at 15 ma signal first Valve open fully.
2. at 20 ma signal Both Valve open fully.

Is This Answer Correct ?    1 Yes 5 No

If a control valve is hunting means means if we are giving 50% to the cv, the cv will open at 51% then slowly slwoly it will reaches 49% , so what to do for solve this problem. The cv is double acting and mounted for anti surge operation, it having 4 nos. volume booster, one sov, one positioner, etc..?

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 =
