For the outstanding design of the process transmitter x|act BD SENSORS was awarded with the IF product design award 2006. Thus the worldwide most famous design award was handed out to a successful medium sized company. This does not only prove the competitiveness of BD SENSORS, but also the independent design competence of the company.
Process manufacturers are faced with multiple considerations when choosing a valve controller/switchbox that will best meet their application needs. Key aspects to consider include product endurance in demanding environments, agency certification, ease of installation, maintenance requirements, and product support.
BD | SENSORS now offers, besides the classic analogue pressure and level transmitters, also devices with digital interfaces. The basis is the interface standard RS 485, which has a high electromagnetic immunity due to the symmetric signal transmission, and which is suitable for a maximum wire length of up to 1 km.
The Badger Meter B-MAG M5000, is ideally suited for leak detection in water networks, water consumption measurements and irrigation plants, the meter has been designed for applications without a power supply where exact consumption or flow rates are required. Of course, the B-MAG™ I M5000 can also be used with an available power supply. The meter can be powered with main voltage, and in case of a mains-failure, it is powered by an internal battery with a lifespan of 12 years. This has the benefit of important data which is saved.
