Vibration Measurements
Screw the sensor onto the magnetic base. Do not forget to remove the plastic cover and a metal
washer (it closes a magnetic field for longer service life of the magnet) before measuring. Place the
plastic cover and the metal washer back on the magnet after measuring.
Place the magnet on a measuring point very carefully. Best is to rest the edge of the magnet on its
side and then slowly lower the sensor onto a machine. If you bring the magnet near to the machine
with its whole area hitting the machine all of the sudden, then the strong impact can irreversibly
destroy the sensor.
In case you use a measuring tip instead of the magnet, measured values are not going to be stable.
This is not surprising. The measured values depend to a large extent on a pressure of the tip at the
measurement point. The magnet that attaches the sensor generates a constant pressure so the values
are stable.
Attention!!! Use the measuring tip only in hard to reach places, where it is not possible to place the
magnetic base.
Temperature measurement
Infrared sensor for temperature measurement is aside from accelerometer input. Measurement angle
is about 45 degrees around the sensor centre axis. Best results are taken with sensor distance 10-20
cm from measured surface. The accuracy of result depends of surface emissivity.
Sensor sensitivity vs. the angle
Measured temperature is displayed in Celsius and Fahrenheit degrees. Also the coloured bar is used.
The bearing symbol on the other displays is also coloured according to the actual temperature value.
The ranges of colours are for less then 30°C - green, 30-45°C - yellow, 45-60°C - orange, 60-75°C -
red and for greater then 75°C – dark red.
