INTRODUCTION
The Metravi VT-145 Machine Condition Monitor with Vibration Tester is a
handheld instrument based on the latest microprocessor design. It can measure
Vibration, Infrared Temperature and features intelligent colour alarm
functions.
The instrument is simple and easy to use, suitable for on-site machine
operation and maintenance inspector to monitor machine condition, detect
problems in time, and ensure reliable operation of machines.
VIBRATION MEASUREMENT
The Metravi VT-145 can measure the effective value of Vibration Velocity (mm/s
RMS), Single Peak Acceleration (g P), Peak-to-Peak Displacement (um P-P) and
high-frequency Acceleration value (BG Peak).
When measuring velocity, the instrument will automatically determine and
indicate the machine alarm status
in colour based on the built-in ISO10816-3 machine vibration standard.
TEMPERATURE MEASUREMENT
In addition to its vibration detection function, the Metravi VT-145 is also
equipped with a non-contact Infrared Thermometer, which is mainly used for
checking bearing temperature. The measuring range is -20°C ~ 120°C, and the
measuring position is indicated by a red laser pointer.
