pressure transmitter is having two parts
first primary sensing device which is in contact with
process physical parameter like pressure and this primary
sensing devise sence the process pressure by various
method's like (LVTD,DP CELL,STARIN GAUGE AND ETC)and
convert this mechanical energy to electrical energy which
is also called as transducer and it is given to the
secandary sensing device of tx which is electronic part for
futher conditioning,to get (4-20) by using 24vdc excitation
voltage and secandry part of tx is also known as convertor
and the o/p of tx is given to indicator or controller
further manipulation.
their other std form of signal also as mentioned in above
