What is the difference between a Extension cable and a copnesating cable.Where can we use compensating cable. Is anywhere compensating cable are used for mv transmission to the indicator.
1 3761You are looking at the RS-485-side of an RS-232/RS-485 converter and the power supply voltage for the converter is +5V. Under idle conditions (no transmission), and assuming you have enabled the RS-485 output: what would you expect at: (a) Output A measured against output B (b) Output A measured against ground (c) Output B measured against ground

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.

dear friends, i have seen flow as the selection critriea in presure guage (bourdon tube) and i would like to know what is the relation between flow and performance of pressure guage other parameters i found in the data sheet are pressure max. 1ksc temperature max. - 50 deg c line size - 80NB operating range - 1ksc pr. guage range - 0-2 ksc thank u,
