The Pfeiffer DigiLine gauges are designed for industrial and research applications requiring total pressure measurement that is reliable and easy to install with digital signal output. The series covers the technically relevant vacuum range with measuring principles encompassing piezo, Pirani, capacitive, hot cathode and cold cathode sensors. All gauges have an RS-485 interface which can be used to connect up to 16 measuring points to a controller. The M12 connector assemblies qualify these vacuum gauges for usage in heavy-duty environments. The gauges can be operated in a communication network with accessories from the current HiPace turbopump range.
The Pfeiffer ActiveLine series offers a wide range of vacuum gauges that work on a variety of measuring principles and have a classic analog signal output. The series thus covers the technically relevant vacuum range from ultra-high vacuum to overpressure. The outlet voltage of the transmitter, that is proportional to the pressure, can be displayed as pressure on the three controllers or read into controllers through analog inputs for further processing.
