Product description

“Pulse 1.02” continuous vibration monitoring sensor.

Purpose of a vibration measurement sensor.

The “PULSE 1.02” instrumentation and control system is designed for continuous stationary measurement and monitoring of mechanical parameters of rotating and non-rotating parts of machines and mechanisms during operation, as well as during maintenance activities (vibration tuning, rotor balancing, etc.), in accordance with GOST 25364-97, GOST 27165-97, ISO 2954:2004, GOST R ISO 10816-1:2007, GOST R ISO 10817-1:2008, or other automated systems.

Composition of vibration monitoring equipment

  • Vibration monitoring modules type IDVP.01.X for non-contact measurement of relative displacement and relative vibration displacement, as well as monitoring of peak-to-peak relative vibration displacement of rotating parts of equipment (units, machines, mechanisms);
  • Vibration monitoring modules type IDVS.01.X for contact measurement of vibration parameters (RMS vibration velocity, peak-to-peak displacement, vibration acceleration amplitude) of non-rotating parts of equipment (units, machines, mechanisms);
  • Displacement monitoring modules (DMM) type IDP.0X.X for non-contact measurement and monitoring of relative displacement of rotating and non-rotating parts of equipment (units, machines, mechanisms), as well as for measurement and monitoring of displacement of stationary parts of machines and mechanisms;
  • Rotational speed monitoring modules (RSM) type IDChO.01 for non-contact measurement and monitoring of rotational speed of rotating machine rotors, including turbine generator rotors and auxiliary equipment at power plants;
  • Tilt angle monitoring modules (TAMM) type IDN.01.X for measurement and monitoring of tilt angle of non-rotating parts of equipment (units, machines, mechanisms);
  • Vibration parameter transducers FP-VS.S for conversion of analog signals (vibration velocity, vibration displacement, or vibration acceleration) and monitoring of vibration parameters (RMS vibration velocity, peak-to-peak displacement, vibration acceleration amplitude) of both rotating and non-rotating parts of equipment (units, machines, mechanisms).

The monitoring modules (MM) can be used as standalone devices for measurement, alarm signaling, and protection of machines and mechanisms against exceedance of limit values, as well as as part of the “Pulse 1.02” control and measuring system, APCS (SCADA), or other automated systems.

Additionally, the MM configuration may include:

  • DIN-rail power supply (Uout 12 V; Iout 1.25 A; Pout 15 W);
  • two-pole 6 A circuit breaker for DIN rail mounting;
  • external indication module MI-01 for remote display of monitored parameters;
  • interface converter S-500-USB-RS485;
  • control panel MC.01;
  • DIN-rail mounting kit for measuring converter installation;
  • software for MC configuration;
  • software for recording measured values.

The vibration monitoring system performs the following functions:

Measurement of:

  • relative vibration displacement of the rotor and other rotating parts of equipment (units, machines, mechanisms);
  • relative displacement of the rotor and other rotating parts of equipment (units, machines, mechanisms);
  • relative displacement of bearing supports and other non-rotating parts of equipment (units, machines, mechanisms);
  • root mean square (RMS) value of bearing support vibration velocity and other non-rotating parts of equipment (units, machines, mechanisms);
  • vibration acceleration amplitude and vibration displacement range of bearing supports and other non-rotating parts of equipment (units, machines, mechanisms);
  • rotational speed of the rotor and other rotating parts of equipment (units, machines, mechanisms);
  • tilt angle of non-rotating parts of equipment (units, machines, mechanisms);
  • other process parameters represented by a standardized AC voltage (current) signal.

Real-time calculation of additional parameters:

  • amplitudes and phases of harmonic vibration components;
  • low-frequency (LF) vibration components;
  • vibration spikes (sudden vibration changes).

Additional system functions:

  • alarm signaling when controlled parameters exceed emergency thresholds, and generation of discrete signals for standard protection and alarm systems;
  • conversion of measured parameters into a standardized DC current signal;
  • generation of analog signals representing instantaneous values of relative vibration displacement suitable for transmission and processing in external data analysis and vibration diagnostics systems;
  • formation of parameter data sets and transmission on request via RS-485 serial interface using Modbus RTU protocol to external display modules, diagnostic systems, and automated process control systems (APCS/SCADA);
  • fault signaling of the primary measuring transducer (PMT), including detection of short circuits or open circuits in the PMT–MC communication line;
  • automatic self-check of control module functionality.
 

All control modules of the “Pulse 1.02” instrumentation system consist of a primary measuring transducer (PMT) and a measuring converter (MC).

The PMT is designed to convert a physical quantity into a frequency-modulated signal.
The MC is intended for digital processing of the signal received from the primary measuring transducer and for outputting measurement data in both analog and digital form.

The MC is based on a unified circuit design and is compatible with all types of PMTs.
Functional invariance across MC types is ensured by connecting the appropriate PMT and installing the corresponding firmware/software in the MC microcontroller.

Configuration of MC parameters (alarm threshold levels for discrete logic signals, amplification factor, conversion coefficient, module address via Modbus protocol, etc.) is performed using a personal computer.

Power supply of the MC is provided by a stabilized ±12 V DC voltage. Power consumption does not exceed 1.5 W.

The signal from the PMT can be transmitted without additional intermediate devices via a shielded cable (type MGShVEV or equivalent) over distances up to 1000 m. The conductor cross-section must be not less than 0.35 mm². External electromagnetic interference is mitigated through amplification with amplitude-limited frequency-modulated signal conditioning at the MC input stage. In this case, requirements regarding the communication line type, cable length, and the monitored object’s metallic structure must be taken into account when configuring the MC.

The measuring converter includes:

  • an input for connecting the PMT;
  • a digital RS-485 interface;
  • discrete outputs for alarm signaling upon exceeding predefined threshold values of the monitored parameter;
  • a discrete output for fault indication of the eddy-current PMT, including short circuit or open-circuit detection in the PMT–MC communication line;
  • an analog current output providing a standardized signal proportional to the monitored parameter;
  • a voltage analog output providing:
    • for vibration monitoring modules of type IDVP.01.X — analog signals of instantaneous vibration displacement / displacement values;
    • for tachometric modules of type IDChO.01 — analog signals of instantaneous pulse sequence (synchronization marks).
