Explosion - proof mark: Ex i b IIC T4 Gb The WA - V168 series vibration meters can measure the vibration of rotating machinery and other equipment. They are capable of measuring the effective value of vibration acceleration and vibration velocity, as well as the peak - to - peak value of displacement, and can measure temperature via infrared. These meters feature easy operation and portability. They are mainly used for the rapid inspection of equipment such as steam turbines, hydroturbines, motors, fans, pumps, compressors, and machine tools, and can also be used for the preventive inspection of mechanical equipment failures. The measured values of the vibration measuring instrument are directly displayed on the liquid crystal display. The instrument is equipped with an AC signal output socket, which can be used for the recording and analysis of vibration signals. During measurement, simply hold the instrument, touch the tip of the instrumen.
