Piezo transducers r der 4 converting mech to elec energy

Also generators also converting mechanical to electrical
energy here the rotation of a conductor is a mechanical energy
so i produce a emf by law of induction and hence electrical
energy is generated..

capillary type tranmitter using remote seals and capillary tubes filled with liquid of known of known density so if you wanna callibrate it just close block valve just before capilary @ high side & connect druck apply it's calibrated range pressure as normal calibration ensure low side block valve must be closed & if you asking commissioning so this is not a DP type pressure tx so simple if you wanna put in servie this tx just open high side block valve & than low side block same way i do it but still transmitter showing -13 ma.just tell me what i want to do ?
