Pfeiffer Extends DigiLine Series
Total pressure vacuum gauges with digital signal output have modular concept, suitable for harsh environments
For more than 20 years, Pfeiffer Vacuum's portfolio has included its DigiLine range of digital total vacuum pressure gauges, which can be modularly adapted to suit any industrial vacuum application. These gauges allow reliable measurement of the total pressure and are easy to install.
Now,extra options have been added to the series to keep abreast of changes in market requirements. This means that DigiLine is now also available with the industrial Ethernet interfaces ProfiNet and EtherCat. In comparison to conventional fieldbuses, these offer the advantage of very fast data rates and a significantly higher number of participants, which makes them an important factor in implementing Industry 4.0.
In addition, Pfeiffer's capacitance gauge types, CCT, which were previously supplied only with an analogue output, are now also available in the DigiLine series. These high-precision measurement instruments can be used independently of the type of gas, and find applications in the precise control of coating processes, for example, as well as in freeze drying and in calibration laboratories. The tried-and-tested ceramic technology in the CCTs has the advantages of good chemical resistance and a very low zero point deviation. The CCTs are available as a temperature-compensated version and a 45degC heated version.
Many vacuum applications operate only within a specific pressure range. DigiLine gauges determine and regulate the total pressure in a vacuum system. Thanks to their digital signal output, they ensure a high degree of accuracy and secure data transmission.
The M12 connector assemblies qualify these vacuum gauges for use in harsh environments. The gauges can be operated within a communications network, along with the HiPace turbopumps and other Pfeiffer Vacuum products.
All of the gauges have an RS-485 interface. The available options already included Profibus DP, DeviceNet and an additional analogue output with two switch points and an LCD display.
