3 terminology and units of measurement
3.1 Static amplitude sensitivity staticamplitudesensitivity
Static calibration, the sensor output value increment increment the urging of the obtained ratio, unit. for piezoelectric sensor
Pico is a [gallons] per cow [Dayton] (pC/N); the strain sensor millivolts per volt [special] cow [Dayton]
(MV/(V · N)).
3.2 magnitude dynamic sensitivity dynamicamplitudesensitivity
Sinusoidal excitation at a given frequency, output amplitude is compared with the input force sensor calibration value, according to the formula
(A.1), said units. for piezoelectric sensor Pico [gallons] per cow [Dayton] (pC/N); for strain gauge
Sensor millivolts per volt [special] cow [Dayton] (mV/(V · N)).
3.3 phase delay phaselag
Sinusoidal excitation force of a given frequency, the phase difference between the output and input power is the school of the sensor, the unit.
degree).
3.4 equivalent mass sensor end equivalentendmassofforcetransducer
During calibration, the inertial force sensor itself part of the quality produced in motion is also applied to move its sensitive element
Force state, this part of the end portion of the equivalent mass called mass unit. kilograms (kg).
4 Overview
Force sensors are typically sensitive element through the signal conditioner will force into an electrical signal, mainly used for a variety of static or
Dynamic force measurements. According to the principle of the sensor, the force sensor strain gauge, piezoelectric, piezoresistive, capacitive, etc.
