BMG’s SPM instruments for onsite vibration measurement-condition monitoring and preventative maintenance

BMG offers the full portfolio of SPM condition monitoring equipment, from basic hand held instruments, to high level on-line systems. Included in this range is the entry level VibChecker portable instrument, designed for reliable on-site vibration measurement and assessment.

“The VibChecker requires minimal operator training and supports BMG’s BearingChecker, which is used to accurately assess the condition of rolling element bearings during operation in equipment like motors, fans, pumps and gearboxes,” says Carlo Beukes, business unit manager, power transmission, BMG. “The VibChecker gives early warning signs of developing machine problems, in order to prevent premature replacement of machine parts. Vibration monitoring is the most widely used preventative maintenance technique for the accurate assessment of the condition of machinery elements – like pump rotors, fan impellors, gearbox gears and housing mountings.


VibChecker for condition monitoring

“Both these instruments are instantly usable and require little training for efficient operation.”

The lightweight user-friendly VibChecker has an ergonomic design, an easy button operation and user-friendly interface, which make it the perfect maintenance tool for plant mechanics, machine operators and maintenance technicians. With this device, vibration monitoring no longer needs to be a question of cost or expertise.


The VibChecker is designed for simple vibration checks and with integrated FFT (Fast Fourier Transform) capabilities, it is also an efficient device for troubleshooting. Periodic vibration checks are easily done and reliable and accurate vibration information is delivered in seconds. Readings are immediately and automatically evaluated according to established ISO standards. These standards make the assumption that limited information – obtained easily and at low cost – is as useful as a detailed analysis, using expensive equipment and elaborate techniques.

This instrument has an internal probe and connector for external ICP transducers. The VibChecker is capable of displacement, velocity and acceleration RMS and ISO 2372/10816 measurement between the 10 and 1000 Hz frequency range.

Accessories include a comfort-grip protective sleeve and a small portable MEMS transducer with magnetic foot, convenient for measurement in narrow spaces.


VibChecker and BearingChecker

BMG’s SPM’s high definition HD technology is a further development of the Shock Pulse Method® (SPM) providing reliable information on the lubrication and mechanical condition of bearings. With sufficient forewarning, plant personnel can either perform required maintenance or schedule a planned component replacement, thus minimising repair costs and reducing downtime.

This condition monitoring system offers continuous bearing and lubrication condition information to compliment regular interruptive inspections that are legally required, by giving the responsible certified engineer critical information about the physical health of bearings while in operation.

Instant evaluation of bearing condition is given in an easily understood green, yellow and red colour code.

With the advanced digital SPM HD technique and RPM based sampling frequency, these devices are perfectly suited for measurement in a broad RPM range, including speed applications as low as 0,1 RPM.

In addition to HD technologies, BMG offers a range of condition monitoring methods for trouble shooting and root cause analysis.

The company’s team of over 140 mobile technicians supports condition monitoring products with a technical skills service, to ensure the highest level of plant output and reliability.

Specialist services include installation, adjustment, replacement and maintenance of components, shaft and pulley alignment, balancing, condition monitoring, oil sampling and analysis and critical equipment inspections and lubrication schedules. Maintenance training and fault diagnosis also form an important part of BMG’s field services.
