In the entry level market where people need a basic handheld vibration tool to indicate vibration severity, two new instruments the Viber X2 and Viber X3 fit into this category.
These battery operated instruments measure the following:
- Vibration measurements in 3 selectable frequency ranges
- Bearing Condition measurement in wide frequency range
- Audible noise on headphone for Bearing condition measurement – X3 only
- Built-in IR temperature sensor – X3 only
- Highest peak frequency and amplitude for troubleshooting
- Colour LEDs for alarms
- High quality sensor on 1 meter cable with magnet or spike attachment.
Detail specifications of the Viber X2/X3 here.
Typical end users:
X2 – Maintenance or repair people who needs a reliable, fast and easy to understand tool for the basic checks in rough conditions.
X3 – Same as for X2, but with additional IR temperature sensor, internally charged NiMH batteries and earphones for bearing condition troubleshooting.
My verdict:
I like the 3 frequency ranges and highest peak calculation – nice for troubleshooting and the Viber X3 with IR Temperature measurement. The accelerometer on the cable, as found on both instruments, makes it easy to get into tight spots ensuring a good quality and repeatable measurement. (Unlike vibration pens). The headphones used for bearing sound will go a long way in convincing sceptics about the true consition of a bearing and its lubrication. The present range from VMI starting at the Viber A, X2, X3, Viber X and Viber X5 and X6 is fairly complete and there is a handheld vibration solution for every budget.
