Answer Posted / animesh
4 -20ma=1-5vdc
we use 250ohmresistor
so1v/250ohm=4ma
&5v/250ohm=20ma

What is stripper & spilitter ? Diffrence in this.?
IS there any effect of vortex in low pressure side of the transmiter after the orific in feed water line? if yes then what is the calculation?
What is the GK Value in Flowmeter?
I am having a Phoenix digital to modbus converter. The o/p of the same is connected to flow computer FB407. But the digital signals are updated only after one minute in the flow computer. what may be the cause of delay in communication? Flow computer is having a scanning period of less than 1 sec.
What are the error values can accepted in flow transmitter calibration?could u give any formula for this?
We are using Rosemount 5400 series Radar Level Transmitters in all types of Sump Applications having oily water hdrocarbon petrochemical nature. What we are facing the problem frequently is that always getting reading frezzed at some value. If we do power recycling , sometimes it is working . then making same freezing problem. If anybody faced before such type of problem and also having solution , Please give the answer.
can u briefly explain aboutan aryton shunt multirange DC ammeter?
Basically iam Instruemntation Engineer, but Iam interested in Instruments design engineering, so plz guide, is there any course, training or Softwres to become Instrument design engineer??.

Specify eight technical requirements that you would consider important, when deciding upon a particular control valve?
A DP transmitter is used to measure the level of an open tank. The drain line of the tank is connected to a control valve, and is configured as, if the level of the tank is 90% the valve should get open 10%. And if the tank level is 10%, the valve should get open 90%. Draw wiring diagram and explain how to configure DP transmitter and control valve using HART communicator. If the span error at output is 1%, what will be the %opening of the control valve at 60% level of the tank?
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 =
