Product Details

1.Introduction

VT-900 series is developed by ourselves. It is a kind of multi-functional equipment for ultra-low frequency vibration measurement. It has been widely applied in different situations for vibration measurement and monitor by companies, universities and scientific research institutes.

2.Applications

Vibration pickup can be used in the following vibration measurement situations:

1.pulsation measurement and vibration monitor of floor and structures

2.pulsation measurement of general engineering structure, such as bridges, buildings, docks, dams and ocean platforms. Vibration measurement and monitor in vibration tests.

3.vibration measurement of large mechanical rotation equipments, such as hydro-generator.

4.weak vibration measurement of vibration isolation platforms and vibration isolation foundation.
