Safety instructions
Use in accordance with the regulations
The P3MB pressure transducer is to be used exclusively for pressure measu-
rement and directly related control tasks. Any other use is deemed to be not
as prescribed.
To ensure safe operation, the transducer must only be used in accordance
with the specifications in the User Manual. It is also essential to comply with
the statutory and safety regulations relevant to the particular application. This
also applies to the use of accessories.
We declare that the transducer is in conformity with the requirements of the
European Pressure Equipment Directive 97/23/EC, directive of the European
Parliament and Council of 29 May 1997 on the approximation of the laws of
the member states concerning pressure equipment.
The pressure transducer is not a safety device as defined in the regulations
for use. The perfectly safe operation of this pressure transducer requires sui-
table transport as well as technically correct storage, installation and assem-
bly coupled with careful operation.
Use as a ”component with a safety function” does not come under appropriate
use and the user must assess this himself (in the sense of the Pressure
Equipment Directive 97/23/EC).
General dangers in non-observance of the safety instructions
The pressure transducer corresponds to the state of the art and is safe to
operate. The pressure transducer can give rise to residual danger if impro-
perly installed and operated by untrained personnel.
All personnel involved in the installation, commissioning, maintenance or
repair of the pressure transducer must have read and understood the User
Manual and in particular the technical safety instructions.
Accident prevention
Care must be taken to ensure that when the pressure transducer is being
installed or removed, there is no pressure in the circuit.
Residual dangers
The scope of the capabilities and components provided with the transducer
covers only a part of pressure measurement technology. Equipment planners,
installers and operators must plan, carry out and accept responsibility for the
safety engineering aspects of pressure measurement technology in such a
way that residual dangers are kept to a minimum.

5
P3MBP BlueLine
A1710-3.3 en HBM
All existing regulations must be complied with. There must be reference to the
residual dangers connected with pressure measurement technology.
Even though the P3MB is designed to be as safe as possible, safety regula-
tions demand that burst protection is provided all round the transducer.
The transducer must be protected against mechanical stress or shock.
The resistance of the steel used in the measuring body is only as stated if the
temperatures never rise above or fall below the limits specified in the data
sheet.
If the temperature limits are exceeded – for example, because there is a fire -
the device is rendered unusable.
The end of service life is reached, if the zero signal has changed significantly.
Residual dangers are highlighted in this operating manual with the following
symbols :
Symbol: DANGER
Meaning: Maximum danger level
Warns of an imminently dangerous situation in which failure to comply with
safety requirements will result in death or serious physical injury.
Symbol: WARNING
Meaning: Potentially dangerous situation
Warns of a potentially dangerous situation in which failure to comply with
safety requirements can result in death or serious physical injury.
Symbol: CAUTION
Meaning: Potentially dangerous situation
Warns of a potentially dangerous situation in which failure to comply with
safety requirements could result in damage to property or some form of
physical injury.

2 Construction and operating mode
BlueLine series pressure transducers (5000 bar, 10,000 bar, 15,000 bar) have
been designed to measure static and dynamic pressures of fluids.
The development of the P3MB BlueLine was based on HBM’s years of expe-
rience in high pressure technology.
Since 1970, devices in accordance with the P3M principle have been working
successfully with a nominal (rated) measuring range up to 3600 bar.
A large number of devices have proved themselves in dynamic applications.
We are now adding to this type series in the high-pressure direction with the
nominal (rated) measuring range 5000 bar and also adding devices with a
range of 10,000 bar and 15,000 bar
The P3MB BlueLine is suitable for dynamic applications:
•The measuring body is made of field-tested, ductile steel
•P3MB measuring bodies for higher pressures with their threaded connector
are made of a single piece of rolled steel – there is no weld or any other
sort of sealing or jointing point.
•The size of the chosen output signal is big enough to enable measured
value adjustments to be made without too much extra work. On the other
hand, the choice of output signal – or the stresses and strains - should be
small enough for dynamic loading to be possible (without the premature
signs of material fatigue).
•Any fluid or gas (vapour) that does not attack these steels is a suitable
measurement medium. The pressure transducer and its threaded connector
are strengthened for the purpose of the pressure connector and can be
installed anywhere. In particular cases there are specific instructions in
Chapter 3 ”Mounting” which must be followed!
The stated properties are protected by FEM calculations and dynamic loading
tests.
The stated measuring body design, chosen for all devices of the P3MB type
series of measuring ranges 500 bar and above, enables the P3MB to meet a
higher safety standard.
Years of reliable use under dynamic load and in rough operating conditions
provide practical proof that the P3MB has a safe and robust design.
Strain gages (S.G.) are attached directly above the measurement hole. They
are coupled to a Wheatstone bridge and to protect them from harsh ambient
conditions, are located in a hermetically sealed reference chamber. This is
made of stainless steel. In this way, the reliability and precision of the trans-
ducers is assured, even if operating conditions are persistently rough.

3 Mounting
CAUTION
•Before installing the P3MB, check that the threaded connector and the
thread in its counterpart are sound and free of burrs. The parts must fit to-
gether easily.
•Use only the seals provided for this purpose by HBM.
•Devices must never be installed in a counterpart without a relief aperture.
The diameter of the relief aperture should not be less than 2mm. Its purpose
is to safely protect the volume at the root between the two parts, the P3M and
the container or pipework, against an increase in pressure. Even if the seal
leaks, this will prevent destructively high forces ever building up.
P3MB BlueLine transducers are sealed at the pressure connection by a
tapered gasket of 58 °in a beveled run-in to the hole of 60°- as is usual and
successful in ultrahigh pressure technology.
The seal is made from corrosion-resistant material - the 5000 bar version
from 1.4301, the 10.000 bar and 15.000 bar versions from 1.4542.
To minimize the volume in the measurement hole (”dead volume“) packing is
used for these measuring ranges. This forms a unit with the sealing plug. This
makes it very easy to install as well.
The pressure connection thread is M 20 x 1.5.
Pressure transducers can be fitted in any position.
But if the transducer is to be used to measure dynamic pressure characteris-
tics in liquids, it is advisable to install it with the pressure connection upward.
In this way you stop gas accumulating in the measurement hole, where con-
tinually changing compression and release can lead to sizable rises in tem-
perature.

When tightening, the wrench (size 27) must only be applied to the
clamping area of the mounting flange, and not to the housing or
cable entry. The permitted tightening torque is 30Nm.

4.1 Cable extension
Use shielded, low-capacitance extension cable. Above all the excitation cir-
cuits must have large cross-sections. HBM supplies its recommended exten-
sion cable and measuring cable by the metre.
When extending cable, ensure perfect connection with lowest possible contact
resistance and good insulation between the circuits and ground. For this
reason all connections must be soldered, or at least made with safe, stable
terminals, and installed so that they are watertight. In the open air and/or in a
damp environment, terminal boxes must be sealed.
When extending the six cores of the standard measuring cable and using a
six-wire circuit amplifier, the cable length does not affect the measuring signal.
Measuring cables should not be laid parallel to high-tension and control cir-
cuits (e.g. in common cable shafts). If this cannot be arranged, protect the
measuring cable with steel conduit and keep it at least 50 cm away from other
cables. Stray fields from transformers, motors and protective contacts are to
be avoided.

5 Measuring
At nominal (rated) load, the devices have an output signal of 1 mV/V.
The transducers have been designed to withstand these loads, however, the
actual conditions resulting from the operating load and the variation of the in-
dividual transducers require appropriate measures to be taken to prevent bur-
sting of the transducer.
The devices are hermetically sealed against the environment - so these are
absolute pressure transducers. If it interferes at all, it is easy to take away the
display of ambient pressure, e.g. 1 bar of 5000 bar, at the amplifier by taring.
The devices have reached the end of their service life if the zero signal has
changed by more than 5% or if there is clearly visible and unscheduled defor-
mation and damage to the device.
5.1 Measuring dynamic pressures
When there is dynamic loading, maximum pressure must not exceed the rated
pressure. The oscillation bandwidth (peak-to-peak) of the permitted pressure
fluctuation must not exceed 70% of the final scale value.
The P3MB/5000 bar is designed for 107alternating loads at approx. 4000 bar
and HBM is aiming to further increase the dynamic strength.
Calibration by reference to static pressures also applies when measuring
dynamic pressures. Please note that in the case of measurement frequencies
in the natural frequency range, amplitude reinforcements have to be taken
into account.
