The KOBOLD pressure measurement converter is used for the electrical remote transmission of a pressure. For use in heavy machinery, engines, shipbuilding and automotive engineering, pressure measurement converters have to be very robustly constructed to ensure that they work perfectly under strong vibrations and with greatly variable ambient temperatures. The device volumes should also be as small as possible so that it is possible to clearly arrange several pressure measurement converters in a small space. The PNK inductance pressure measurement converter described below meets the requirements. Function When subjected to pressure the Bourdon tube is deflected laterally. The degree of deflection is converted into a proportional electrical measurement using a contact-free differential transformer. At the output of an integrated amplifier there is an available memorised current of 0 (4) to 20 mA or a voltage of 0 - 10 V. The minus poles of the emergency voltage (24 VDC) and the output signals are connected with one another.
