Vibration Meters

A damaged roller bearing can result in production stop if not attended to in due time. Usually a fault in a roller bearing can be detected long time before it develops into a situation of unbalance.

In order to detect early roller bearing defects you could measure the overall acceleration value in the 1 kHz to 10 kHz frequency area, where roller bearing resonances can be detected.

Vibration and bearing resonances

PCH 4050 Vibration Checker

The PCH 4050 Vibration Checker is a portable vibration meter for unbalance, misalignment and bearing noise measurements. You can measure the vibration level in 3 units; velocity, acceleration and in displacement. The PCH 4050 complies with the DIN/ISO 10816 standard. Furthermore, the PCH 4050 measures bearing noise in the 1 kHz - 10 kHz area. You simply place the measuring tip on the bearing housing and the vibration level is displayed immediately.

PCH 4051 Vibration Checker

The PCH 4051 Vibration Checker includes a separate accelerometer with a strong magnet for measurements on hard-to-reach machine parts. You can measure the vibration level in 3 units; velocity, acceleration and in displacement. The PCH 4051 complies with the DIN/ISO 10816 standard. Furthermore, the PCH 4051 measures bearing noise in the 1 kHz - 10 kHz area. If you use a magnet, or a threaded stud, for positioning the accelerometer you get a more repeatable measuring results. This is very recommendable when you make several measurements and want to compare the data over time.
