IDVS.01 Bearing Parameter Monitoring Instrument
Product description
IDVS.01 Bearing Vibration Measurement Sensor
The IDVS.01 Vibration Monitoring Module (VMM) is designed for contact measurement of vibration parameters (RMS vibration velocity, vibration displacement peak-to-peak value, and vibration acceleration amplitude) of non-rotating parts of equipment (units, machines, and mechanisms).
The IDVS.01 Vibration Monitoring Module can be used both as a standalone module for measurement, alarm signaling, and protection of machines and mechanisms against exceeding emergency threshold levels of monitored parameters, and as part of the “PULS 1.02” monitoring and measuring system, process control automation systems (PCS/SCADA), or other automated systems.
Composition of the IDVS.01 Vibration Monitoring Module
The IDVS.01 Vibration Monitoring Module consists of:
-
a contact single-channel eddy-current primary measuring transducer (PMT) of the PP-IS type;
-
a measuring converter (MC) of the FP-IS type.
The IDVS.01 Vibration Monitoring Module Provides
-
continuous measurement of vibration parameters (RMS vibration velocity, vibration acceleration amplitude, or vibration displacement peak-to-peak value) of non-rotating equipment parts;
-
monitoring and alarm signaling for exceeding emergency threshold levels (3 levels) of vibration parameters (RMS vibration velocity, vibration acceleration amplitude, or vibration displacement peak-to-peak value), vibration jump detection, and exceeding low-frequency (LF) vibration levels;
-
transmission of measured vibration parameter values, as well as amplitudes and phases of harmonic components, via the RS-485 serial interface to external recording and visualization devices;
-
fault signaling for the primary measuring transducer (PMT), including short circuit or open circuit conditions in the communication line between the PMT and the measuring converter (MC);
-
transmission of information on аварійні events and faults via the RS-485 serial interface to external recording and visualization devices;
-
generation of discrete output signals for vibration jump events, exceeding LF vibration levels, and reaching emergency threshold levels of vibration parameters for external alarm systems;
-
generation of a standardized 4–20 mA DC analog output signal proportional to the vibration parameter (RMS vibration velocity, vibration acceleration amplitude, or vibration displacement peak-to-peak value);
-
automatic compensation of ambient temperature influence (temperature compensation) on the measured vibration parameter value;
-
automatic functional self-diagnostics.
