Vibration Sensor Module

The Vibration Sensor Module is a specialized electronic component designed for integration within the Integrated Testing Module. Its primary function is to monitor vibration levels during equipment testing and operation, converting mechanical vibrations into electrical signals for analysis. This data is essential for assessing machine health, detecting imbalances, and preventing failures in industrial testing environments.

The module employs piezoelectric, MEMS, or electromagnetic sensing elements to detect vibrations. When subjected to mechanical vibration, the sensing element generates a proportional electrical signal (voltage or current), which is then conditioned and processed by onboard circuitry for accurate measurement and analysis.

Key specifications include a measurement range of ±50 g peak acceleration, a frequency range of 10–1000 Hz, and a sensitivity of 100 mV/g ±10% at 160 Hz and 10 g. The accuracy is ±5% of full scale. The output signal is a 4–20 mA two-wire loop, and the supply voltage is 12–36 V DC with reverse polarity protection. The operating temperature range is -40 to 85 °C, and the protection class is IP67 per IEC 60529. The housing is made of stainless steel 316L (ASTM A182), and the weight is 150 g ±5 g without cable. The mounting thread is M8 x 1.25 (ISO 965), with a recommended torque of 10 Nm. The shock limit is 5000 g for a 1 ms half-sine pulse.

These values are reference ranges for the product family; actual model-specific values must be verified with the legal manufacturer or supplier. The module is intended for use in industrial testing and condition monitoring applications. When selecting or integrating this module, confirm that the specifications meet your application requirements, and verify compliance with relevant standards. Regular calibration and maintenance are recommended to ensure accurate readings. If the output signal deviates from expected values or the module fails to respond, it may indicate a fault or damage; in such cases, consult the manufacturer for troubleshooting or replacement.

The Vibration Sensor Module operates on the principle of converting mechanical vibration into an electrical signal. It uses piezoelectric, MEMS, or electromagnetic sensing elements. When the module is subjected to vibration, the sensing element deforms or moves, generating a voltage or current proportional to the vibration's acceleration. This signal is then conditioned by onboard circuitry, which may include amplification, filtering, and conversion to a standard 4–20 mA output. The conditioned signal is transmitted to a monitoring system for analysis, allowing for the assessment of machine health and detection of anomalies.
