SPECIFICATIONS RION VM-82A: GENERAL-PURPOSE VIBRATION METER
— Piezoelectric Accelerometer PV-57エ (supplied)
Type: Shear-type piezoelectric accelerometer (CCLD compatible)
Sensitivity: 5.1 mV/(m/s2) (±15 %) 80 Hz, 23 °C
Frequency range: 1 Hz to 5 kHz (±10 %)
Dimensions / Weight: 17 (width across hexagonal flat) × 49 mm / 45 g
— Applicable standards: CE marking, WEEE Directive, Chinese RoHS. EMC standards: IEC 61326-1、CISPR 11、IEC 61000-6-2
— Measurement range (using PV-57エ)
ACC (Acceleration): 0.02 to 200 m/s2 EQ PEAK 1 Hz to 5 kHz
VEL (Velocity): 0.3 to 1 000 mm/s RMS 3 Hz to 1 kHz; 0.1 to 1 000 mm/s RMS 10 Hz to 1 kHz
DISP (Displacement): 0.02 to 100 mm EQ PEAK 3 Hz to 500 Hz; 0.001 to 100 mm EQ PEAK 10 Hz to 500 Hz
— Frequency range
ACC (Acceleration): 3 Hz to 1 kHz, 3 Hz to 5 kHz, 1 Hz to 100 Hz, 3 Hz to 20 kHz
VEL (Velocity): 10 Hz to 1 kHz, 3 Hz to 1 kHz
DISP (Displacement): 10 Hz to 500 Hz, 3 Hz to 500 Hz
Values represent the range measured to about 10 % attenuation from flat response, due to high-pass filter or low-pass filter action. Electrical characteristics for velocity from 10 Hz to 1 kHz are compliant with the frequency range requirements of JIS B 0907 “Mechanical vibration of rotating and reciprocating machinery – Requirements for instruments for measuring vibration severity”.
— Measurement full-scale range
For accelerometer PV-57エ and accelerometers with sensitivity: 1.0 to 9.9 mV/(m/s2)
ACC (Acceleration): 1, 10, 100, 1000 m/s2
VEL (Velocity): 10, 100, 1000 mm/s
DISP (Displacement): 0.1, 1, 10, 100 mm
