III. Companion Usage

Must be Complemented: PR6423/014-040 + CON021

Power Supply: Preamplifier -24VDC (-18 to -30VDC)

IV. Installation and Debugging Key Points

Standard Installation Gap: 2.5mm, adjust to preamplifier output -12V for locking

Align and lock the LEMO aviation connector to prevent loosening and jumping

The shielding layer is grounded only at a single point on the cabinet side, while the probe end is left floating

14-meter-long cable should be laid away from power cables and frequency converters to reduce interference

V. Applicable Scenarios

Steam turbines, compressors, fans, gas turbines

Used for shaft vibration, shaft displacement, eccentricity, and phase monitoring

Compatible with MMS6000 / AMS6500 TSI systems
