Data Acquisition System with increased Safety

28 May 2014 - bmcm introduced a DAQ system with next-generation network technology. With "PoE", the new DAQ system LAN-AD16fx features not just more flexibility but also increased safety for measuring. At SENSOR+TEST trade show BMC Messsysteme GmbH (bmcm) will first-time present the latest release of his high-end DAQ system which records signals via network at many remote measuring points via great distances.

The LAN-AD16fx has been equipped with new features, but is still available at the same price of the previous model LAN-AD16f.

Especially to mention is the PoE function: "Power over Ethernet" means that the device is supplied via the Ethernet cable. This is a great advantage in case of missing power supply or tight space at the measuring point and saves installation costs.

The following points demonstrate the safety aspects of the LAN-AD16fx:

1. Safety against power failure

Due to the central PoE supply of all DAQ systems, measuring setups with test points at many different places only need one common UPS (Uninterruptible Power Supply) unit being installed. Loss of measured data caused by mains failure can be prevented with low costs.

2. Safe data transmission

The integrated TCP/IP protocol checks if all sent data packages arrive correctly. Communication between the DAQ system and the PC that does not arrive will be resent.

3. Safe sampling

With 250kHz overall sampling rate, even smallest signal peaks will not remain undetected. Especially when transmitting high amounts of data, the network technology of the LAN-AD16fx is unbeatable.

4. Safety against interferences and dangerous potentials

All channels, power supply, and PC are galvanically isolated from each other and safe against any perturbations. Even with 100m cable length, 12.95W usable power is guaranteed according to the IEEE802.3 standard. High potentials created by connecting machines or other consumer load do not affect DAQ system or PC.

5. Safety for humans and PC

Measurements across great distances are no problem if using the network. If the measuring point is in rough environment (e.g. extreme height, dirt, acrid fumes), the PC is installed in the laboratory. The technician can analyze the measured signals in comfortable environment without being exposed to harmful effects.

6. Reliable measuring results

Several LAN-AD16fx devices installed at different places allow for synchronous sampling in real-time. The overlay of measured data makes the detection of correlations and after-effects much easier.
