4 - Technical Data (ctd)
The Pirani gauges AP/APN 2004 have been designed for vacuum
measurements of gases in the pressure range of 1000 mbar to
5x10
-4
mbar.
They are active gauges. The gauges of 0/10V type can be oper-
ated with an Adixen controller (ACS 2000 or ACM2000) or as a
stand alone gauge sending a signal directly to other equipment. The
gauges of RS485 type can be operated only with RS485 customer’s
equipment.
These gauges must not be used for measuring fl ammable or
combustible gases which react in air.

Connect the gauge to the installation using appropriate fitting
accessories conform to using maximum pressure (1) (from the
Adixen product catalog).
Connect the cable (2). Use cable ties or other methods to support
the cable so that its weight does not put excessive strain on the
connector (3).
5 - Installation
Connection
Do not touch the inside surfaces of this gauge with bare hands,
especially the inlet flange. Fingerprints will increase outgassing in
the gauge and cause erroneous pressure readings.
Install this gauge on the vacuum system with care. If it is
necessary to reposition it, do not twist or bend the sensor by the
electronic enclosure. Disconnect the gauge, position it in the correct
position, and connect it again.
Install this gauge away from vibration. High vibration can cause
the gauge to malfunction.
These gauges are designed to operate in any orientation. Install
the gauges horizontally for higher accuracy.
Install this gauge away from drastic temperature changes (away
from any heat sources or fans) for higher accuracy.

Do not use or apply voltage or ground to the pins marked “not used”.
Select the correct wire size for voltage if you use your own cable
( 4 p. 4)
(1)
.
Always connect the protective ground wires or an electric shock can result.
Install a circuit breaker on the power source. Disregarding these
instructions can cause damage and/or injury.
(1) ”D-Sub” 9P (female) connector is available to allow the gauge
to be connected directly to customer equipment. (
3 p. 3).
Do not exceed the receivable maximum pressure ( 4 p. 4). If
the maximum pressure of the gauge is exceeded, it can lead to gas
leakage and cause injury.
Do not open the installation on which a gauge is installed when
the internal pressure is above 1 bar. Internal components may be
ejected and cause personal injury.
Do not use these gauges with corrosive, toxic, flammable or
explosive gasses.
Do not heat these gauges beyond 70 °C. Disregarding this
instruction can cause damage to the gauge circuits or a vacuum
leak.
Symbols used
This type of warning is used to indicate a potential risk that can
cause serious injury or death if instructions are not followed.
This type of warning is used to indicate an imminent risk that can
cause serious injury or death if instructions are not followed.
This type of warning is used to indicate a potential risk that can
cause significant damage to the equipment and/or installations if
instructions are not followed.
Use an Appropriate Power Source
Do not use this gauge with a power supply over 30V DC.
Disregarding this maximum voltage can cause product damage or
personnel injury.
Use appropriate grounds
An appropriate protective ground connection is mandatory to
avoid electric shock in the event of a fault. Make sure there is no
difference in protective ground potential between gauge head and
controller device/power supply.
Use Caution when installing this gauge.
Check that there are no harmful gasses or vapors within the lines
or chambers before opening them to install this gauge. Clean and
purge with a clean dry gas to remove these harmful gasses or
vapors if necessary.
Do not over pressure
Do not pressurize the inside of this gauge beyond the receivable
maximum pressure. Disregarding this can lead to either damage to
this gauge, or a gas leakage which may cause personnel injury.
Do not use these gauges for corrosive or toxic gasses
Do not use this gauge with corrosive, toxic, flammable or explosive
gasses, as this can lead to gas leakage and cause injury.
Maintenance of the product
Do not disassemble the gauge head or electronics sub-assembly.
Refer to section 8 for sub-assembly replacement Instructions.
Do not modify the product
Do not modify the electrical or mechanical components of these
gauges. Any modification could cause damage or personnel injury.
Skilled personnel
All work described in this document should be carried out only
by qualified persons who have suitable technical training and the
necessary experience.
