Core advantages and usage instructions

Anti interference design: shell insulation+internal shielding, avoiding interference from grounding loops and frame voltage on measurement, suitable for complex industrial environments.

Stability performance: Excellent bias voltage stability under high temperature, low noise level, ensuring measurement accuracy.

Calibration feature: Dynamic calibration is completed at the factory, and no additional calibration is required for subsequent use, reducing maintenance costs.

Applicable scenarios: Suitable for industrial machinery vibration monitoring, especially for equipment status monitoring in harsh environments.
