Product Performance

The kit adopts 24-bit high-precision A/D conversion chip and anti-aliasing filter circuit, with vibration signal measurement error ≤0.1% and shaft displacement measurement resolution up to 0.1μm, ensuring subtle changes in equipment status can be accurately captured. The 4-channel independent signal conditioning architecture supports synchronous sampling, and the sampling rate of 1024 points/sec/channel can fully record high-frequency vibration impact signals (up to 10kHz spectrum analysis).

Integrated with real-time fault diagnosis algorithm, it can automatically identify typical fault modes such as unbalance, misalignment and shaft bending, with fault response time ≤10ms, and quickly trigger equipment interlock shutdown via relay output. The data transmission delay with 3500 system main controller is ≤5ms, supporting online parameter configuration (alarm threshold, range calibration) and firmware upgrade through System 1 software, without system shutdown for maintenance.

Channel-level 2.5kV AC isolation design combined with shielded terminal board provides common mode rejection ratio ≥100dB, effectively resisting electromagnetic interference and ground loops in industrial sites. The overall wide temperature adaptability and reinforced structure design ensure mean time between failures (MTBF) ≥300,000 hours, fully adapting to the high-reliability monitoring needs of key rotating equipment.
