Millimar. Electrical Length Measuring Instruments General Technical Data of Inductive Probes The measuring principle of inductive probes is based on the change of position of a 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 S 1 II 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 frequence KHz 19.4 13 7.5 5 P2001 P2004 P2104 192 73.75 115 78.74 Sensitivity mV V mm P1300 1300 1301 1303 1304 K 1318 192 - P2010 19.2 29.5 11.5 7.874 1310 19.2 - 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 .
