Millimar Electrical Length Measuring Instruments M 7-5 Mahr General Technical Data of Inductive Probes The measuring principle of inductive probes is based on the change of position of the magnets conductive core moving within a coil system generally this is distinguished between a half bridge and LVDT's. The Mahr P2000 series of probes applies a high linear patented VLDT transducer which is similar to an LVDT transducer. This also operates according to a differential transformer principle. f 1 ir ii Half Bridge HB (Differential Choke Coil) LVDT (Linear Variable Differential Transducer) VLDT (Very Linear Differential Transducer) Electrical specification of various compatibilities type Mahr tesa Marposs Mahr-Federal Carrier frequency KHz 19.4 13 7.5 5 P2001 P2004 192 73.75 115 78.74 P2104 P1300 192 73.75 Sensitivity mV V mm 1301 1303 192 1304 K 1318 P2010 19.2 29.5 11.5 7.874 Amplitude Veff 5 3 3.5 2 Schematic drawings of Mahr input amplifiers according to the various compatibilities Oscillator ( Connector pin (contact side) j Mahr .
