METHOD FOR NONELECTRICAL QUANTITIES MEASUREMENT BY MEANS OF MULTIPLE-POINT INSTRUMENTATION SYSTEM WITH TRANSFER FUNCTION MONITORING FEATURE, AND INSTRUMENTATION SYSTEM FOR IMPLEMENTATION THEREOF

摘要

FIELD: physics, instrumentation technology.;SUBSTANCE: invention refers to instrumentation technology and can be implemented for accuracy monitoring in multiple-point instrumentation systems. Distinctive feature of the method is as follows: simulator is disconnected from the system after calibration, and simulation stages driver is disconnected from inputs of simulation stages switching circuit and connected directly to one of the inputs of sensors switching circuit. Instrumentation system with transfer function monitoring feature comprises recording instrument with sensors switching units and sensor signal simulator in form of the stages driver and switching circuit similar to said system sensors switching circuit. Control inputs of simulator switching circuit are connected to corresponding control outputs of the recording instrument. This ensures specified accuracy of sensor signal measurement, reduces time required to determine transfer function factors of the instrumentation system during measurements, and provides for simpler design of signal simulator.;EFFECT: provision of specified accuracy of signal measurement, improvement of the instrument response and its design simplification.;2 cl, 2 dwg
