2 Device description
2.1 Product description
The NOVION® allows a wide range pressure measurement from 1 × 10−11 mbar to 1000
mbar (atmospheric pressure), as well as the detection of helium and residual gas analysis
function from mass number 1 to 300. The use of a novel ion trap combines numerous
functions in a compact sensor.
In the total pressure range 1000 mbar (atmospheric pressure) to 5 × 10−3 mbar, a heat
conduction sensor (Pirani) is used to determine the total pressure parameter.
In the total pressure range 5 × 10−3 to 1 × 10−11 mbar a hot cathode ionization sensor is
used to determine the parameters total pressure and partial pressure helium as well as for
residual gas analysis. With this sensor electrons are emitted by means of heated filaments.
The electrons generated in this way are used to impact gas particles in the measuring
volume and collect them in an ion trap. The collected ions are then accelerated to a Faraday
Cup and evaluated using time-of-flight analysis. The parameters total pressure and partial
pressure in the measuring volume are determined from the collected data. Switching
between the measuring principles is fully automatic.
The supply voltages for the heat conduction sensor and the hot cathode sensor are provided
by the operating unit on the device. The operating unit also provides the required output
signals and interfaces for displaying the measured parameters on an external display or on
an external computer.
NOVION® features a wide range of functions and intuitive software. Traditional vacuum
sensors for total pressure measurement and residual gas analysis are replaced by a compact
and cost-effective NOVION®.
2.2 intended use
The device is used exclusively for pressure measurement of non-flammable gases and gas
mixtures in a vacuum system in the pressure range 1 × 10−11 to 1000 mbar. It may only be
connected to components intended for this purpose.

3.3.4 Establish power supply
The power supply must be ensured for commissioning. For this purpose, first connect the
supplied mains adapter to the power connection socket (1) and then connect the mains
adapter to the mains using the supplied power cable. Alternatively, it is possible to use
existing 24 Volt DC voltage sources to guarantee the power supply. An adapter is required
for this. The power supply socket (1) has the following wiring:
Contact
Parameters
(+)
-23 Volt to 25 VDC
-30 Watt
(-)
-GND
-Must be grounded

Operation
NOVION Instruction manual 19
When using your own power sources, always ensure that the minimum requirements for the
operating voltage and power of the source are met. This source must also be grounded.
3.3.5 Establishing the data connection (cable)
An input / output connector in the form of an RJ45 socket is located on the rear of the
NOVION® control gear for communication and data exchange with the device. The function
of the contacts of this socket is explained in the following figure. The socket is connected to
a PC via the supplied RJ45 connection cable and the supplied RJ45 / Sub-D9 adapter.
Attention
The supplied RJ45 connection cable must not be connected to an Ethernet
socket on the PC side. Incorrect connection and inadmissible voltages can
damage the NOVION® operating unit.

3.3.6 Establishing the data connection (Bluetooth)
Reference
Attention: By establishing a Bluetooth connection an active cable connection is
disconnected.
If your NOVION® operating unit has the Bluetooth option, it is possible to ensure wireless
communication. For this purpose, the used terminal device must also have Bluetooth. In
delivery state, the Bluetooth interface of the NOVION® operating device is activated and
visible for other devices. The terminal device used must search for Bluetooth devices. As
soon as the NOVION® operating device is visible in the list of found devices, pairing can take
place. Afterwards, a "virtual" serial interface (COM port) is available. The remaining
communication is identical to the wired serial connections.
The name under which the device is found in the Bluetooth environment corresponds to the
following scheme:
"NOVION-<serial number>" (Example: NOVION-12345678)
