Description
The CombiPress™ PFMN industrial and PFMH hygienic version pressure transmitter is a high end programmable instrument for
measuring pressure from full vacuum to 400 bar gauge pressure or 0 to 400 bar absolute pressure.
CombiPress™ series are supplied to industrial applications with threaded connections or with hygienic connections for hygienic
applications. All wetted parts are in stainless steel AISI 316L (or better). The connection can be mounted as bottom connection or
as rear connection.
PFMx is powered by a 10…35 VDC power supply, featuring an analogue 4...20 mA output signal. A version with 4...20 mA signal
with HART® and an ATEX-version is available.
The CombiPress™ can be mounted with or without a display. The version with display utilizes the Baumer CombiView™ DFON
display, which is connected to the transmitter via the internal UnitCom ribbon cable. The DFON is supplied with power and a digital
signal for measured value, programming etc., which is more reliable and with better accuracy, than using a 4…20 mA loop. In
instruments with UnitCom both the transmitter and display can be programmed at the same time or separate programming of each
device can be selected.
The DFON has a unique background colour setting. Three colours are available – White / Red / Green and further the red and
green colour can be set as flashing as a warning.
The DFON has two integrated galvanic separated relays. The instrument can be delivered with or without activated relays. If supplied without activated relays, those can be activated by purchasing a license code from Baumer. By entering the code to the instrument via the FlexProgrammer the relays are enabled.
The DFON can be programmed by the touch screen on the display or by the FlexProgrammer 9701 Baumer programming unit with
the Baumer FlexProgram installed on a PC.

Installation
Operators instructions
CombiPress™, type PFMx
If the transmitter is visibly damaged, it should not be put into
operation.
The pressure diaphragm must not be touched during installation. Cleaning with high pressure cleaners and tools may damage the diaphragm.
If the transmitter has a G½A connection, check before mounting that the depth of the hole is at least 20 mm.
For correct installation in 3A connections please see page 2.
Mounting the pressure transmitter in a closed system (e.g. a
valve) may create overpressure higher than permitted, which
can deform and damage the diaphragm.
Measuring ranges and over pressure safety
Cell range, bar 0...0,345 -1...1 -1...5 -1...20 -1...34 -1...68 -1...400
Over pressure 1 3 15 60 70 135 690
Burst pressure 2 6 30 120 170 270 1.350
The freezing point of the filling liquid must not be exceeded
White oil -10°C
Silicone oil -40°C
The maximum temperature for the filling liquid is 200°C.
Though the maximum temperature is limited by the mechanical
construction for standard connection to 125°C.
During CIP the temperature may reach 150°C for max. 1 hour.
Installation procedure
The pressure transmitter can change zero point slightly, owing to
mechanical tension and the fitting direction selected for the pressure diaphragm. Optimal results are therefore achieved if the
zero point is adjusted after the pressure transmitter has been
mounted in place in the application.
Electrical installation
Suitable cables should be used to secure maximum tightness in
the gland. For models having a plug for electrical connection the
inner part of the plug must be oriented in a way so that the opening is turning downwards.
To avoid measuring errors resulting from insufficient supply voltage, the transmitter must be supplied with min. 10 VDC at 23
mA. When mounted with DFON display the minimum voltage will
be 14,5 or 16,5 VDC, depending on the setting of the background light.
The transmitter has a high immunity against high-frequency interference. In environments with a high radiation it is recommended to use screened and twisted cable.
Accuracy, turn down
The specifications for accuracy apply to full scale (FS). at 20°C
However the below results are tested and will under normal conditions apply
Accuracy: 0,10%/FS@20°C will apply for up to 2:1 turn down
0,25%/FS@20°C will apply for up to 4:1 turn down
a) Remove protection-cap.
b) Install CombiPress™ in the application
c) Connect the power supply
d) If needed, configure span by the touch screen, FlexPro-
grammer or a HART configurator.
e) If needed, configure the 0-point (4 mA) by pressing the
0-botton for about 5 second (slow blinking diode in app.
5 sec after which the diode will blink fast and the 0-point is
set) or use the facility in the FlexProgrammer or the HART
configurator.
The electronic zero point can be adjusted from -10...10% of the
measuring range.
The correct zero point pressure must be established prior to
adjusting the zero point. Tank and pressure transmitter must
have the same temperature. If the pressure transmitter has a
relative measuring cell from 0 bar, the zero point pressure is the
same as the atmospheric pressure or the level in a tank selected as zero point level. A pressure transmitter measuring absolute pressure has a zero point lower than 1 mbar abs.
You can revert to the factory set zero point correction by recon-
figuring the CombiPress™ with the FlexProgrammer and select-
ing factory setting.
