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.

The Pfeiffer CenterLine uses state-of-the-art controllers that allow communication via USB and Ethernet interfaces, and the brilliant LCD screen makes it easier to read the measured value. The gauges are automatically detected by the controller, which makes for safe and easy installation. In addition to the analog output, some gauges have set points for better process control.

The Pfeiffer ModulLine series includes three Pirani TPR vacuum gauges with a measuring range of 760 to 0.6 mTorr, three IKR cold cathode vacuum gauges with a measuring range of 3.75 mTorr to 7.5 · 10-12 Torr, and two IMR hot cathode vacuum gauges with a measuring range of 17.5 mTorr to 1.5· 10-12 Torr. Since these vacuum gauges do not contain any electronics, they are also suitable for use in high-radiation environments. An extensive range of cables, including high-temperature cables and cables with double shielding, and two controllers, complete this measurement equipment line. The individually configurable TPG 300 controllers can have two measuring boards for up to four TPR and IKR-type vacuum gauges. Another socket is for an interface board for serial interfaces RS-232/RS-485 and relay contacts. Controller IMG 400 is used for connecting IMR-type vacuum gauges. Both controllers can also be connected to Profibus DP with an optional interface board.

The Pfeiffer Handheld TPG 201 and 202 gauges are battery-operated offering an easy way to display and record pressures. The TPG 201 works on the principle of heat transfer (Pirani). The TPG 202 also has a piezo-resistive pressure transducer for the higher-pressure range, which works irrespective of the type of gas. Depending upon the unit, the handheld gauges cover the pressure range of between 900 Torr and 3.75· 10-4 Torr. Handheld units are equipped with a display which allows the pressure to be read off directly on the unit. The readings can also be read out through the USB interface with the aid of DokuStar software. A handy accessory case is optionally available.
