Describe all types and levels (4-20mA, 0-10V, mV, pulse,
etc.)of analog and digital I/O used in process control
application.
Answer Posted / parmar.ic@gmail,com
all types and levels are 4-20ma and 0-10mv v pule etc
because in industries somthing we assume in 0mA so the
control room is not understand outbut on the panel is not
display so any signal are come in panel and out put is
uderstand so 4ma any signal and it understand this procees
is any problem .so analo and digital I/O used in process
controle application are levels 4-20mA and 0-10v,mV

The Design Calculation of Level Transmitter For Different Structure open & Closed Vessel, Eg. Diff. Level Tx., Capacitance For Continous Operation
Hi Friends , i need one urgent help , i am preparing for M.tech entrance examination , i need some obejective questions related to instrumentation field. where can i get those ? can anyone help me pls ?
1.what is controller proportional gain 2.what is the controller intergral action time. 3.A proportional plus derivative controller that has a proportional band of 20% and a derivative action time of 0.1 minutes. Construct the shape of the output waveform for the triangular input if the input rises and falls at the rate of 4 units per minute.
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..?
