1. Safety
Intended use
The sensor measures pressure of liquids and
gases within the range of –40 … 200 °C.
The sensor must only be used for media against
which the housing material and sensor tip are
resistant.
Staff qualication
Only use staff who are trained for the activities
described. This applies in particular to assembly,
installation, conguration and troubleshooting.
Make sure that the staff have read and understood
these instructions.
Electrical connection and EMC
All electrical wirings must comply with local
standards and connections must be made
according to the connection diagrams.
Technical condition
Only use sensor in perfect technical condition.
Only use Baumer accessories.
Baumer will accept no liability for other
manufacturers’ accessories.
Operation
The power supply and environmental conditions
must comply with the specications of the device.
Before switching the device on and off, possible
effects on other equipment and the process run
must be checked.
Risk of burns from hot media
During operation the sensor housing may warm
up to over 50 ºC. When working with hot media
provide protection against burns.

3 Flush diaphragm
The PFMH/N is a high-end programmable
pressure transmitter for industrial or hygienic
applications. The sensor measures pressure in
all gaseous and liquid processes through a ush
diaphragm. Pressures from full vacuum to 400
bar gauge pressure or from 0 to 400 bar absolute
pressure can be measured with the sensor.
Programming can be done via the touch screen
display or via the FlexProgrammer 9701. During
operation, the display shows information regarding
measured values, alarms and other data.

1. Sicherheit
Bestimmungsgemässe Verwendung
Der Sensor dient zum Messen des Drucks
von Flüssigkeiten und Gasen im Bereich
–40 … 200 °C.
Der Sensor darf nur für Medien eingesetzt
werden, gegen die das Gehäusematerial und die
Sensorspitze resistent sind.
Personalqualikation
Setzen Sie nur Mitarbeiter ein, die zur
Durchführung solcher Arbeiten ausgebildet
wurden. Dies gilt insbesondere für Montage,
Installation, Konguration und Störungsbehebung.
Sicherstellen, dass das Personal diese Anleitung
gelesen und verstanden hat.
Elektrischer Anschluss und EMV
Sämtliche elektrische Leitungen müssen die
örtlichen Auagen erfüllen und Verbindungen sind
anhand der Anschlussbilder durchzuführen.
Technischer Zustand
Den Sensor nur dann benutzen, wenn er sich
in einem einwandfreien technischen Zustand
bendet.
Nur Zubehör von Baumer verwenden.
Für Zubehör anderer Hersteller übernimmt Baumer
keine Haftung.
Betrieb
Die Stromversorgung und die
Umgebungsbedingungen müssen die
Gerätespezizierungen erfüllen.
Bevor Sie das Gerät ein- und ausschalten, prüfen
ob eventuelle Auswirkungen auf andere Geräte
und den Prozessablauf vorhanden sind.
Verbrennungsgefahr bei heissen Medien
Das Gehäuse des Sensors kann sich im Betrieb
auf über 50 °C erwärmen. Bei heissen Medien für
Verbrennungsschutz sorgen.

durch eine frontbündige Membrane den Druck aller
gasförmigen und üssigen Prozessmedien. Die
Relativdruckmessung ist von Vakuum bis 400 bar,
die Absolutdruckmessung von 0 bis 400 bar
möglich.
Die Programmierung kann über den Touchscreen
