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 accurate equipment condition data acquisition. 4-channel independent signal conditioning design supports synchronous sampling with sampling rate 1024 points/sec/channel, which can capture high-frequency vibration impact signals.

Integrated with real-time fault diagnosis function, it supports peak/peak-to-peak monitoring, spectrum analysis (0-10kHz) and trend tracking, with fault response time ≤10ms, triggering equipment interlock protection via relay output. Data transmission delay with 3500 system controller is ≤5ms, supporting online configuration parameters (alarm value, range) and firmware upgrade without shutdown for maintenance.

Wide temperature design combined with shielded cable provides common mode rejection ratio ≥100dB, effectively resisting electromagnetic interference in industrial sites. The overall mean time between failures (MTBF) ≥300,000 hours, complying with API 670 rotating machinery monitoring standard and SIL 2 safety level requirements.
