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

When accelerometer sensitivity is 0.1 to 0.99 mV/(m/s2), range increases by a factor of 10

When accelerometer sensitivity is 10 to 99 mV/(m/s2), range decreases by a factor of 1/10
