Accelerometer PCE-VM 31

measures vibrations in hands, arms, and the whole body / measurement ranges for acceleration, velocity, and displacement / memory with capacity for 10,000 measurements

The PCE-VM 31 accelerometer for the human body measures vibrations present in the hands, arms, and throughout the body according to ISO 5349 and ISO 2631 standards. This human body accelerometer stands out for its measurement ranges of acceleration, displacement velocity, and for measuring vibrations caused by machines. Additionally, it is capable of displaying all the values you may need, such as the intermediate and moving effective value (RMS), the maximum effective value (MTVV), the vibration dose value (VDV), the total vibration value, limit values, and maximum values. With the PCE-VM 31 human body accelerometer, you can also measure vibrations in the driver's seats through an additional measurement channel. On the other hand, the PCE-VM 31 human body accelerometer has a three-channel FFT analyzer to find the main frequencies and a TEDS support for automatic sensor recognition. The accelerometer's integrated memory has a capacity for up to 10,000 measurements and, thanks to its USB interface, you can easily transmit measurement data to a computer. Its compact design and ease of use make this accelerometer an ideal tool for conducting safety measurements in the workplace.
