Vibration Sensor with MEMS Accelerometer(VP-8021A / VP-8021B / VP-8021C)
Vibration sensor with a built-in MEMS accelerometer element that can measure up to high frequencies.
Vibration Sensor is a device that converts vibration into an electrical signal.
It is important to select the right vibration pickup for accurate vibration measurement.
Vibration sensor (waveform output): Waveform output is a representation of the vibration amplitude over time. It is suitable for observing changes in vibration frequency and amplitude.
Vibration sensor with a built-in MEMS accelerometer element that can measure up to high frequencies.
Principle of reciprocal pendulum type sensor is
to induce voltage by reciprocal motion of the
seismic mass with a coil in the magnetic field
being suspended by a diaphragm or coil spring.
The force applied to the piezoelectric element
generates an electric charge proportional to the acceleration.
Capable of handling high vibration frequencies and large accelerations.
The servo type sensor is commonly used in earthquake monitoring and measurements of micro tremors on civil engineering structures due to its high sensitivity, stability, and accuracy in the lower frequency range compared to other vibration transducers.
Covers ultra-low acceleration up to high-frequency mechanical vibration.
A piezo-resistive sensor has a stable structure composed on a silicon chip created using micromachining and semiconductor production technology.
Vibration sensor (level output): Level output is a representation of the vibration amplitude relative to a fixed reference value. It is suitable for comparing vibration strength.
Compact 3-channel charge amplifier. This unit is connected to a piezoelectric accelerometer and outputs acceleration waveforms as voltage.
Covers a frequency range of 1 Hz-100 kHz. All conversion of measured values and changing of units is automatic.
Connects output of charge piezoelectric accelerometer to the logger or oscilloscope.
This sensor supplies the current required to drive a sensor with a built-in preamplifier, and the waveform output from it can be accessed from the output terminal or BNC receptacle.
