FIELD: instrumentation.
SUBSTANCE: invention relates to in-situ calibration of inertial transducers. Method for calibration of inertial transducers mounted at operating equipment comprises data collection from inertial transducers and temperature transducers located nearby the former at idle equipment. Mathematical model of systematic temperature error for inertial transducers is corrected on the basis of aforesaid collected data. Note here that data collection is initiated in preset time after actuation of operating equipment. Note here that said transducers that make a sensory subsystem are supplied for data collection at idle operation equipment. Inertial transducer to implement abode described process includes sensory subsystem. It comprises one or more inertial transducers, one or more temperature transducers connected therewith, low-power digitiser configured to collect data from said transducers and processor. The latter incorporates memory to store aforesaid mathematical model and power controller to supply power to sensory subsystem for data collection at idle working equipment.
EFFECT: ruled out errors caused by automotive engine vibrations.
