  • The measuring device consists:
  • measuring system - the physical nature of the conversion values ​​for torque
  • hand
  • dials with scales
  • control springs - directive (control) torque
  • damping
  • The measuring set consists:
  • measuring devices
  • bridges
  • auxiliary equipment
  • Measuring instruments - basic terminology
  • Names of devices according to the measured quantities:
  • voltage - voltmeter
  • current - ammeter
  • resistance - an ohmmeter
  • power - wattmeter
  • frequency - frequency meters
  • power factor - (cosφ) - phase meters
  • cosVAΩWHzMeasuring instruments - basic terminology
  • The names of sets according to the measured variables:
  • Resistance - Wheatstone bridge
  • Inductance - Maxwell-Wien bridge
  • The essence of of measuring devices
  • Types of measuring systems:
  • with a rotating magnet – 1
  • magnetoelectric – 2
  • electromagnetic – 4
  • electrodynamic – 5
  • ferodynamic - (electrodynamic with iron) – 6
  • Induction – 7
  • Thermal – 8
  • electrostatic – 9
  • Resonance – 10
  • magnetoelectric with rectifier – 11
  • magnetoelectric with thermocouple - 12
  • The essence of measuring devices
  • Types of measurement device hands:
  • blade, filiform - accurate, laboratory instruments
  • lanceolate - Panel Meters
  • Reed - switchboard apparatus
  • The essence of measuring devices
  • Types of rotating storage with handle:
  • cylindrical storage
  • very low friction,
  • impact is easily damaged.
  • pivot storage
  • larger friction than the cylindrical bearing
  • but mechanically robust.
