how u measure dp in dp tx? how u calibrate a dp tx?
Answer Posted / s. kanniyappan
The measuring the difference between HP and LP of a process
will give dp.
By connecting a pressure source with t-off to master gauge
to the HP side and venting the LP side to the atmosphere,
varying the pressure according to the range and measuring
the mA in series and adjusting zero and span according to
the variation.
In case of of Dry leg connecting a pressure source with
t-off to master gauge to the LP side and venting the HP side
to the atmosphere, varying the pressure according to the
range and measuring the mA in series and adjusting zero and
span according to the variation.
