A magnetic field (brc) always exists around the current (I) carrying conductor. When this current carrying conductor is subjected to external magnetic field (Bap), the conductor experiences a force perpendicular to the direction of I and Bap. This is because, the magnetic field produced by the conductor and the applied magnetic field try to align with each other. The similar effect one can see between any two magnets.

The same principle is used in electromagnetic pump. The current is supplied through a conducting liquid. And two permanent magnets are arranged to produce magnetic field Bap as shown in the figure. The supplied current has current density (J) and the magnetic field associated with this current can be called as 'Reaction magnetic Field (brc)'. The two magnetic fields Bap and brc try to align with each other. This causes the mechanical motion of the fluid.

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 ?
