Vibration measuring device VIB-8

vib8Multichannel vibration parameters measuring devices VIB-8 are designed to measure and transduce AC voltage output signals from the primary vibration transducers (vibration speed and vibration acceleration).

The devices have 8 measuring channels with successive internal commutation. The devices additionally provide stabilized supply current, necessary for the operation of piezoelectric sensors with an electronic preamplifier (Integrated Circuit Piezoelectric — ICP).

Commutation of the measuring channels as well as AD conversion and processing of the measuring results is carried out for each channel successively. Commutation of the measuring channels, digital processing, storage and exchange of information via RS-485 (Modbus RTU) and Ethernet (Modbus TCP/IP) interfaces is carried out under the control of microprocessor.

The devices are applied for control and balancing of the mechanisms in oil, gas, electrotechnical and other industries which use rotary units (gas-, steam- and hydro turbines, compressors, pumps, electric motors etc.).
