In most instances, measurement applications are not feasible under laboratory conditions. Humidity and dirt constitute a great challenge to the technician in measurement technology. Especially in long-term measurements, they can represent a serious danger to successfully carry out the measurement task.
Outdoor measuring applications, such as load tests at rail tracks, bridges or buildings, often have to be carried out over a long period to detect changes. The measurement technology used must be able to brave wind and weather.
In the industrial production, data acquisition systems serving for quality control and monitoring of the industrial plant are exposed to extreme load caused by dirt particles.
If it comes to breakdowns or failures of a measurement system, unreliable measuring results and unpleasant costs are the consequence. However, the reason is not necessarily the bad quality of the measurement technology used, but can be attributed to negative influences from the outside in many cases.
These problems are met by the newly released ZU-PBOX series from BMC Messsysteme GmbH (bmcm), longtime manufacturer for data acquisition and PC technology.

Different components of a measurement system, like data acquisition system, measuring amplifier or connector panels can be accommodated in the waterproof plastic housings with clear hinged cover (available interior space: 351mm (13.82–) width, 242mm (9.53–) depth, 120mm (4.72–) height). For safe installation, those are mounted firmly on three DIN rails.
The boxes are available in two versions.
The universal type ZU-PBOX-PG is provided with 8 PG screw connectors with strain relief to attach sensors and power supply.
Since many outdoor applications are often realized via network, the ZU-PBOX-LAN has been optimized for LAN data acquisition systems featuring pre-assembled connectors for LAN, synchronization and DC. The connectors are high-quality flange plug connectors.
Up to 16 channels can be attached. Because type and connection of the signals mainly depend on the used LAN data acquisition system and the application, the customer has the possibility to choose the flange connectors for the signal channels (4- or 7-pole female connectors).
As an additional service, mounting and wiring can be ordered at bmcm, too (option ZU-PBOX-MT).
The ZU-POX housings are perfect to use with measurement technology from bmcm. For example, the ZU-PBOX-LAN combined with the LAN data acquisition system iM-AD25a, two analog backplanes AP8 and respective 5B amplifiers (MA series) features a compact and universal LAN data acquisition system with 16 galvanically isolated analog inputs, 25kHz total sampling rate and 16 bit resolution – protected against splash water, dust and other foreign substances, ideal for field use.
With the ZU-PBOX housings BMC Messsysteme GmbH creates a functionally reliable solution for robust measuring applications on-site. Further information at www.bmcm.de/us/
