Safety instructions
Appropriate use
The P2V pressure transmitter is to be used exclusively for pressure measure
ment tasks and directly related control tasks. Use for any purpose other than
the above shall be deemed to be inappropriate.
In the interests of safety, the device should only be operated as described in
the Operating Manual. It is also essential to observe the appropriate legal and
safety regulations for the application concerned during use. The same applies
to the use of accessories.
We hereby declare that this device conforms to the requirements of Pressure
Directive 97/23/EC, the European Parliament and Council Directive of May 29
1997, which approximates the legal provisions of the Member States concern
ing pressure equipment.
The pressure transmitter is not a safety element within the meaning of its use
as intended. Proper and safe operation of this pressure transmitter requires
proper transportation, correct storage, assembly and mounting and careful
operation.
It is not appropriate for use as an “accessory with a safety function”, in
accordance with the regulations and this must be assessed by the user (within
the meaning of Pressure Equipment Directive 97/23/EC) for the particular situ
ation.
General dangers of failing to follow the safety instructions
The P2V pressure transmitter corresponds to the state of the art and is
failsafe. The device may give rise to further dangers if it is inappropriately
installed and operated by untrained personnel.
Any person instructed to carry out installation, commissioning, maintenance or
repair of the device must have read and understood the Operating Manual
and in particular the technical safety instructions.
Accident prevention
You must make sure that the line is not under pressure when installing or
removing the pressure transmitter.
Remaining dangers
The scope of supply and performance of the transducer covers only a small
area of measurement technology. In addition, equipment planners, installers
and operators should plan, implement and respond to the safety engineering
considerations of pressure measurement technology in such a way as to min
imize remaining dangers. Prevailing regulations must be complied with at all

5
P2VA1, P2VA2
A1564-5.5 en/de HBM
times. There must be reference to the remaining dangers associated with
pressure measurement technology.
Although the P2V is designed for maximum safety, safety engineering regula
tions demand that burst protection is implemented around the transducer.
The transducer must be protected against mechanical loads or knocks.
The resistance of the steel of the measuring body only applies if temperatures
are never allowed to fall below or rise above the limits specified in the data
sheet.
If these temperature limits are exceeded, in the event of fire, for example, the
transducer will be unusable.
A significant change in the zero signal shows that the device has come to the
end of its service life.
Remaining dangers are indicated in this operating manual by 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 lead to damage to property, slight or moderate
physical injury.

2 Application
In the measuring system, the P2V transducer corresponds to HBM's proven
passive strain gage absolute pressure transducers, with a measuring body
made from one piece of material. A high-quality analog sensor amplifier and a
digital control for signal correction are also integrated in the enclosure.
All that is seen of this circuitry on the outside is what looks like an active
sensor output with 0.5 to 10 volts (or a 3-wire current output of 4 to 20 mA.) .
The additional microcontroller monitors the sensor temperature and the cur
rent pressure and generates correction signals, so that systematic sensor
errors such as temperature coefficients and the linearity deviation can be
compensated for internally. The individual adjustment and correction data can
be transferred to the transducer during production. HBM's TEDS digital identi
fication system is also available (compatible with the 1-wire EEPROM
DS2433, MikroLan from Messrs Maxim / Dallas).
NOTE:
The 0 V power supply (pin 3) and 0 V output (pin 2) lines are
linked internally.

Blow-off opening:
The transducer housing features a blow-off opening under the blue label (see
figure):
Blow-off opening
This safety device enables overpressure to be reduced in a controlled way in
the event of bursting of the sensing element. This prevents overloading of the
sensor housing. The blow-off opening opens at approx. 10 bar.

3 Mechanical installation
CAUTION
Before installing the P2V, check that the threaded connector and
the thread in its mating component are sound and without
burrs. The parts must be easy to join together.
The pressure transducer can be screwed in wherever required. If the transducer
is used to measure dynamic pressure characteristics in liquids, it should be
installed with the pressure connection pointing upward, so that it not possible for
an air cushion to build up in the measuring tube that could, for example, heat up
unacceptably in the event of adiabatic effects as a result of dynamic loads.
Transducers with measuring ranges of 100 ... 2000 bar are connected with their
G1/4"external thread pressure connection. A 58°tapered seal made of 1.4301
corrosion-resistant material is supplied for this purpose.
The G1/4"pressure connection thread with the tapered seal is suitable for the
usual 17 mm hole depth and a drilled diameter of 4 mm (with a margin of
between 0 and 0.5x45°, also see Specifications).
The tapered seal is fixed accurately and securely in the measuring aperture of
the transmitter by means of the small, stainless steel retaining spring that is
among the items supplied for each seal. The device can thus be fitted and
sealed extremely efficiently.
Transducers with measuring ranges of 3000 bar and higher are connected with
their M16x1.5 external thread pressure connection directly to conventional high
pressure pipes with their 58°taper.
CAUTION:
During installation, screwing torque must not be applied over the
enclosure or the cable entry. Wrenches (SW 24) must be used to
screw-fasten the pressure transmitter. The permissible tightening
torque for measuring ranges 100 ... 2000 bar is 30 Nm; for measur
ing ranges 3000 and 7000 bar, the permissible tightening torque is
30 ... 50 Nm

NOTE:
The 0 V power supply (pin 3) and 0 V output (pin 2) lines are
linked internally.
The transducer is designed for direct voltage operation (15 to 30 volts).
The circuit is intended for operating with a separated extra-low voltage (SELV
circuit). It is not intended for connection to a dc network in accordance with
EN 61010-1.
Should the equipment be operated on a dc voltage network, additional pre
cautions must be taken to discharge excess voltages.
NOTE:
The P2V meets EMC guideline requirements (a condition of the
transducer being granted the CE mark).
To prevent measured value errors when there is heavy high-fre
quency interference, a shielded connection cable with a metal
female cable connector must be used, with the cable shielding
connected to the entire surface of the female cable connector. The
enclosed HBM connection cable meets this requirement.
4.1 Electrical signal
The output signal of the P2VA1 pressure transmitter at 0 pressure is 0.5 V, for
the P2VA2 pressure transmitter, it is 4 mA.
The output signal of the P2VA1 pressure transmitter at nominal (rated) pres
sure is 10 V and for the P2VA2 it is 20 mA. Accordingly the output signal span
(sensitivity) for the P2VA1 is 9.5 V and for the P2VA2, 16 mA.
The displayed pressure is calculated from:
P2VA1: Pabs = ( Uout -0.5 V ) * nominal (rated) pressure / 9.5 V
P2VA1: Pabs = ( Uout -4 V ) * nominal (rated) pressure / 16 mA

4.2 TEDS transducer identification
At connection 5 (to ground at 3), there is a digital identification system avail
able. The basis for this is a 1-wire EEPROM DS2433, from Messrs Maxim/
Dallas.
TEDS stands for “Transducer Electronic Data Sheet”. An electronic data sheet
is stored in the transducer as defined in the IEEE 1451.4 standard, making it
possible for the measuring amplifier to be set up automatically. A suitably
equipped amplifier imports the transducer characteristics (electronic data
sheet), translates them into its own settings and measurement can then start.
HBM provides you with the TEDS Editor for storing your data. This is included
in the software for the MGCplus Setup Assistant.
The Editor also makes it possible to manage the different user rights, to pro
tect the fundamental transducer data from being inadvertently overwritten.
Contents of the TEDS memory as defined in IEEE 1451.4:
The information in the TEDS memory is organized into templates which are
prestructured to store defined groups of data in table form. Only the entered
values are stored in the TEDS memory itself.
The amplifier firmware assigns the interpretation of the respective numerical
values. This places a very low demand on the TEDS memory.
The memory contents are divided into four areas:
Area 1:
An internationally unique identification number (cannot be changed).
Area 2:
The base area (basic TEDS), to the configuration defined in standard
IEEE1451.4. The transducer type, the manufacturer and the transducer serial
number are contained here.
Area 3:
Data specified by the manufacturer are contained in this area:
The data specifies
- the transducer type,
- the measured quantity,
- the electrical output signal,
- the required excitation.
Area 4:
The actual user can modify the last of these areas with, for instance:
- a short comment in text form,
- filter settings,
- zero value.

5 Measuring dynamic pressures
During dynamic loading, the maximum pressures should not be greater than
the nominal pressure.
The transducers are designed for these loads, but the actual conditions from
the operating load and the typical spread require safety measures against the
transducer bursting.
Calibration related to static pressures is also applicable when measuring
dynamic pressures.
