2 7102when an eddy current probe is installed inside of a turbine or compressor in case of probe problem same as:crash of head of probe,changing the scale factor because of low measuring gap(physical gap is ok(example=1.14mm)but voltage is reduced(example=-6 volts),is any way to check the probe,when the ohm of probe is ok.thank you,(Karim Tavakoli)

We Have Two Field bus Pressure Transmitters of Different Sensor Range (I.E One is of Lower range and Another is of Higher Range).Is same Process Line. My Question is Can i provide Saturation Limit to my field Bus Transmitter as We can provide Saturation current limit to HART Instruments. As During Low Pressure Both Working OK ,But During High Pressure, transmitter with Lower sensor range Goes to Fault mode as Beyond its Sensor Limit it can Measure, So may I provide Saturation point Some where to Suppress This Fault during High Pressure.
Can u tell me the principle of the tc,rtd,level switch,pressure switch ,transmitter(pr flow level temp.),vibration...plz

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?
