Basic information
Model: EPRO PR6423/010-140
Type: Vibration sensor
Technical characteristics
Multi-channel monitoring: The sensor is a configurable 4-channel monitor module capable of monitoring multiple physical quantities simultaneously.
Non-contact measurement: The principle of eddy current sensor is adopted to achieve non-contact measurement, avoiding direct contact with the measured object.
Differential signal processing: The shell vibration signal can be extracted from the relative vibration of the shaft, which provides important information for shaft measurement of large gas and steam turbines.
