Measurement Guidelines
Performing Vibration Measurements
Measurements are typically performed with the machine operating under normal
conditions. For example, when the machinery has reached its normal operating
temperature and is running under its normal rated condition (at rated voltage, flow,
pressure and load). For machines with varying speeds or loads, perform measurements
at all extreme rating conditions, as well as at selected conditions within these limits.
Place the sensor’s magnet on the machine’s measurement point. When placing the
sensor on the machine, generally avoid greasy, oily, or wet surfaces, housing splits, and
structural gaps. Select the best measurement point (specifically avoid unloaded bearing
zones), and be consistent in terms of sensor position, sensor angle, and contact
pressure.
If possible, choose a flat surface in the bearing’s load zone. Measurements should be
taken at the same precise location (moving the probe only a few inches can produce
drastically different vibration readings). To ensure measurements are taken in the exact
same spot, mark the measurement point with permanent ink.
Proper hand-held sensor technique is vital to the accuracy of measurements. It is
critical that you perform consistent readings.
Performing Infrared Temperature Measurements
To perform accurate non-contact infrared temperature measurements, bear in mind
infrared sensor cleanliness. The infrared sensor has a small opening. Dirt, grease or oil
may enter the opening and cause inaccurate temperature measurements. If necessary,
clean the opening using alcohol and cotton buds.
