Answer / sam

There are some difference in some areas like "area" in sq
feet and tons of force but nothing that concern us in
instrumentation. PSI is PSI all over the world and so is all
other units of measure we use in instrumentation. The UOM
that are slightly different between US and UK is not of any
importance to us.

All of these difference are also in the imperial system and
there are no differences when you work in the metric system.

In the area of pressure specifically, there is only the ton
of force that are only 1,2 more than the other and that is
not something you will ever use. The same is true for all
other UOM for temp, flow, level, density and all the ones we
use.
Good luck

We have a Yokogawa Micro-XL DCS, which is having around 300 I/O, but whenever there is any wire gets grounded in field, the 24v supply to all loops gets dipped & all the indications at DCS goes to IOP(shows input open), at present we have fixed 500mA fuses in all the lines but which does not working. Does it required to replace with lower amps fuse, then how much or is there any other solution for this.
