Difference from 330780-91-00

330780-90-00: Panel installation (Panel Mount)

330780-91-00: DIN rail installation

The electrical parameters are the same, only the installation method is different.

Installation Points

The total length of the entire system must be strictly 9.0m (probe + cable + preamplifier internal)

Shielded wire single-ended grounding (on the preamplifier side)

For non-explosion-proof steam turbines, fans, compressors, etc. shaft vibration/positioning monitoring.
