Máy đo độ rung Rion VM-83

The VM-83 can be used with a very wide range of piezo electric and servo accelerometers. With a suitable servo accelerometer (such as the Rion LS-10) the VM-83 can be used to measure very low (0.1 – 1 Hz) frequency vibration levels. The VM-83 is very accurate and has very low levels of internal noise and the clear full information display makes it an excellent choice for a laboratory instrument or for precision or low level vibration measurements.

• Clear full information display displays the measurement result and instrument settings
• Very simple and quick operation
• Frequency range 1 – 20 000 Hz with suitable charge accelerometer
• Frequency range 0.1 Hz – 100 Hz with suitable servo accelerometer (e.g. Rion LS-10)
• Accelerometer sensitivity range 0.03 – 99.9 pC/ms-2
• CCLD Accelerometers also supported
• Low noise floor (e.g. 0.0005 ms-2 with Rion PV-87)
• Up to 20 hours operation on Alkaline C-cells
• Selectable High Pass and Low Pass Filters
• Bar graph linear display giving an analogue view of the 100 ms sampled value
• 4 digit numeric display showing arithmetic average of 20 instantaneous (i.e. 100 ms) samples updated every 2 seconds
• Both d.c and a.c. signal outputs
• Serial interface for instrument control and data transfer
