PCT No. PCT/EP88/00203 Sec. 371 Date Nov. 13, 1989 Sec. 102(e) Date Nov. 13, 1989 PCT Filed Mar. 15, 1988 PCT Pub. No. WO89/08819 PCT Pub. Date Sep. 21, 1989.A transducer-system that corrects the actual output of each transducer (11) in the system so as to approximate a desired transducer output, i.e., one where the measured variable such as pressure is directly proportional to the actual physical variable. A connector (15) to each transducer (11) includes special calibration indicators for identifying any innacuracies in its output signal, and monitoring and correction circuitry (13) is selectively attachable to any of the transducers (11), to read the calibration indicators and appropriately adjust the transducers output signal, thereby correcting the identified inaccuracies. A preferred form for the calibration indicators is a set of eight resistors (R1-R8). Subsets of this set correct for zero level, span, and linearity of the transducer (11). |
