What are the advantages of the Accumeasure Capacitive Sensor vs Eddy Current?
Eddy Current Capacitive Sensor Calibration is influenced by target material propertiesCalibration NOT influenced by target material properties Typically output is noisier than capacitive sensorLower noise than eddy current Susceptible to driftVery stable and repeatable output Calibration influenced by temperature of target materialCalibration NOT influenced by temperature of target material Calibration influenced by magnetic fields near sensorCalibration NOT influenced by magnetic fields near sensor • Minimal Phase Delay with Accumeasure 5000 amplifiers. See answer The Accumeasure 5000 Capacitance Displacement Amplifier has a high carrier frequency of 100kHz and is ideally suited for displacement measurements from DC to greater than 20kHz. For most applications its phase delay is adequate, but when it is necessary to get very low delay in the displacement signal (e.g.: a servo control), an optional Bessel filter can be ordered. Ordinarily the Accumeasure 5000 amplifier is provided with
