Product Performance

The kit adopts high-precision signal conditioning circuit, ensuring differential expansion measurement resolution up to 0.1μm and shaft displacement measurement error ≤±0.33% of full scale, enabling accurate capture of subtle equipment position changes. It supports 7 position measurement types, and the channel pair programming function allows flexible configuration of monitoring functions. The dedicated case expansion monitoring design for channels 3-4 meets the special monitoring needs of large rotating machinery.

Integrated with real-time alarm configuration function, it supports two-level alarm threshold settings (alert and danger) with alarm response time ≤10ms. Through 3500 system configuration software, measurement types, filtering parameters and output signals can be configured online, supporting seamless compatibility with 3500/20 RIM modules with firmware version G or higher.

Wide temperature design and EMC optimization (compliant with EN 61000-4 standards) ensure stable operation in industrial strong electromagnetic environments. Channel-level electrical isolation design effectively eliminates ground loop interference. The overall mean time between failures (MTBF) ≥300,000 hours, and sensors are recommended to be calibrated every 5 years to maintain measurement accuracy.
