Monitor your critical machinery 24/7

A3800 – Online vibration monitoring system

The A3800 is a compact size on-line monitoring and diagnostic system. Every factory has some critical machines on which the whole production rely on. Such a machinery should not be checked by portable devices on regular basis but they should be monitored continuously in order to know their “health” anytime. Information about vibration and related process values such as temperature, gives you and advantage of planned machinery repairs and decreases unexpected shut downs which are extremely expensive for your factory.

A3800

A3800 top panel

4, 8, 12 or 16 channels available
Upgradable from 4ch to 8ch and more just via email
Each group of 4ch has one Tacho / speed probe input
Same number of DC channels for process values available
Individual groups of 4 channels are multiplexed

Collect data with DDS

A3800 + DDS software

A3800 measurement setting has never been easier. Create your machinery and measurement points structure in DDS software, assign A3800 device and start the data collection. Data from the A3800 into your PC can go through Ethernet or Wi-Fi network.

Analyze with Virtual Unit

A3800 + Virtual Unit

A3800 unit can be also used as a powerful multichannel analyzer. The setting and control is made by VA5 Pro - Virtual Unit software (free download).
