Machine Condition Monitor VibroGard-M

Product catalog summary
Overview
The document describes the VibroGard-M, a modular machine condition monitoring system designed for cost-effective monitoring of specific tasks in machines such as fans, pumps, compressors, and machine tools. It evaluates voltage and constant current outputs using the VibroGard-M limit contact module or a machine controller, with measurement values displayed via analogue or digital instruments.

Applications
The system is used for condition monitoring of machines and machine lines, including:
  • Rotational speed
  • Overall vibration
  • Roller bearing condition
  • Vibration displacement
  • Two-dimensional vibration
  • Position and elongation
  • Process values
  • Monitoring machines with roller sleeve bearings
  • Evaluation of relative shaft vibration according to ISO and/or API standards

Description
VibroGard-M is a modular system that can be customized for specific applications. It includes modules for measuring overall vibration and bearing condition on machines with roller bearings, as well as absolute and two-dimensional relative shaft vibrations on machines with sleeve bearings. It also measures axial shaft position, shaft elongation, and housing elongation of thermal machines, along with rotational speed and other process values like pressure and temperature.

Advantages
  • Modular design
  • Customization for specific applications
  • Excellent cost-performance ratio
  • Standard sensor interfaces
  • Compact design

Technical Specifications

  • Voltage supply: 115/230 V, 50/60 Hz or 24 VDC
  • Power demand: approx. 2 VA
  • Dimensions: Various, e.g., 135 mm x 60 mm x 90 mm
  • Weight: 0.4 kg
  • Protective rating: IP30

Monitoring Control Units
The document details various monitoring control units for different measurements, including:
  • Vibration displacement, velocity, and acceleration
  • Roller bearing condition
  • Axial shaft position, relative shaft elongation, and absolute housing elongation
Each unit has specific measuring ranges, outputs, and operating frequency ranges.

Limit Contact Module
The limit contact module includes pre and main alarms with adjustable alarm delays and switching capacities. It supports quiescent and load current circuits.
