Rion รุ่น VM-83 เครื่องวัดความสั่นสะเทือนสำหรับงานทั่วไป,General-purpose vibration meter

The VM-83 is a general-purpose vibration meter designed for measurement and evaluation of vibrations, using a piezoelectric accelerometer or a servo accelerometer. It provides four types of input connectors and allows selection of acceleration, velocity, and displacement measurement. With the optional servo accelerometer, even very low frequency vibrations in the range of 0.1 to 1 Hz can be measured, something that is very hard to achieve with conventional piezoelectric accelerometers.

• Display characteristics can be switched to true RMS, equivalent peak, and equivalent peak-to-peak. A comparator with level evaluation output is available. AC output, DC output, and a serial interface are provided as standard equipment. The unit has a box type enclosure and can be powered from batteries or an AC adapter.
• All vibration measurements acceleration, velocity and displacement.
• For Piezoelectric and Servo accelerometers
• DSP operation Max and Peak hold
