1.3 Intended Use
The differential pressure transmitter is only suited to measure
positive, negative, or differential pressure. With pressure
application on both sides, the difference in pressure between the
positive and negative side is calculated and converted into a
proportional electrical signal.
The user must check whether the device is suited for the
selected use. In case of doubt, please contact our sales
department (info@bdsensors.de | Tel.: +49 (0) 9235 9811 0).
BD|SENSORS assumes no liability for any wrong selection and
the consequences thereof!
The fluids that can be measured are gases and liquids that are
compatible with the materials in contact with the fluids,
described in the data sheet.
1.4 Limitation of Liability and Warranty
Failure to observe the instructions or technical regulations,
improper use and use not as intended, and alteration of or
damage to the device will result in the forfeiture of warranty and
liability claims.

3. Mounting
3.1 Mounting and Safety Instructions
Danger of death from airborne parts,
leaking fluid, electric shock
-
Improper installation may result in
electric shock!
-
Always mount the device in a
DANGER
depressurized and de-energized
condition!
NOTE
– If there is increased risk of damage to the device by
lightning strike or overvoltage, increased lightning protection
must additionally be provided!
NOTE
– Treat any unprotected diaphragm with utmost care;
this can be damaged very easily. (The diaphragm is located in
the inner space of the flange)
NOTE
–
Make sure that the mounting does not cause any
inadmissibly high mechanical stresses on the pressure port, as these
could result in a shift of the characteristic curve or in damage. This is
particularly the case for very small pressure ranges.
NOTE
–
Provide for a cooling section if the device is used in a
steam line.
NOTES
–
for mounting outdoors or in a moist
environment:
- Connect the device electrically straightaway after mounting or
prevent moisture penetration, e.g. by a suitable protective cap.
(The protection rating specified on the data sheet applies to the
connected device.)
- Select the mounting position such that splashed and condensed
water can drain off. Stationary liquid on sealing surfaces must be
excluded!
- If the device has a cable outlet, the outgoing cable must be
routed downwards. If the cable needs to be routed upwards, this
must be done in an initially downward curve.
- Mount the device such that it is protected from direct solar
radiation. In the most unfavourable case, direct solar radiation
leads to the exceeding of the permissible operating temperature.
3.2 Mounting Steps for NPT Connections
NOTE
–
Do not remove the packaging or protective caps of the
device until shortly before the mounting procedure, to exclude any
damage to the diaphragm and the threads!
Protective caps must be kept! Dispose of the packaging properly!
NOTE
–
The specified tightening torques must not be exceeded!
To be observed:
The higher pressure is connected to the "+" inlet
The lower pressure is connected to the "-" inlet
Suitable fluid-compatible sealing material, e.g. PTFE tape, is
available
1.
Screw the connections into the ports provided.
2.
Then tighten the connection using an open-end wrench (for
1/4" NPT: approx. 30 Nm).
NOTE
–
The specified tightening torques must not be exceeded!
4. Electrical Installation
Danger of death from airborne parts,
leaking fluid, electric shock
-
Improper installation may result in
electric shock!
-
DANGER
Always mount the device in a
depressurized and de-energized
condition!
For devices with connection terminals, the connection
must be made such that the isolation distances
according to standard are observed and that loosening of
the connecting lines is impossible.
When the electrical installation is being carried out, at
least the protection rating of IP 20 must be ensured!
NOTE –
Use a shielded and twisted multicore cable for the
electrical connection.
1.
Screw off the cover to electrically connect the device with
connection terminals.
2.
Connect the device electrically according to the following
table and wiring diagram:
3.
Before the cover is screwed on again, the O-ring and sealing
surface on the housing must be checked for damage and, if
necessary, replaced!
4.
Then screw on the cover and make sure that the housing is
tightly closed again.

-
Always service the device in a
depressurized and de-energized
DANGER
condition!
Danger of injury from aggressive fluids
or pollutants
-
Depending on the measured medium,
this may constitute a danger to the
operator.
WARNING
-
Wear suitable protective clothing
e.g. gloves, safety goggles.
In principle, the device requires no maintenance.
If necessary, clean the housing of the device using a moist cloth
and a non-aggressive cleaning solution.
Cleaning of the diaphragm:
Deposits or contamination may occur on the diaphragm in case
of certain fluids. It is recommended to establish appropriate
maintenance intervals for checking purposes.
Clean the diaphragm cautiously using a non-aggressive cleaning
solution and a soft paintbrush or sponge.
If the diaphragm is calcified, it is recommended to have the
decalcification performed by BD|SENSORS. Please note the
chapter "Service/Repair" with regard to this.
NOTE –
Wrong cleaning may damage the measuring cell
beyond repair. Do not use any sharp or pointed item, or
compressed air to clean the diaphragm.

10.1 Recalibration
The offset value or range value may shift during the life of the
device. In this case, a deviating signal value in relation to the set
lower or upper measuring range value is output. If one of these
two phenomena occurs after extended use, a recalibration in the
factory is recommended. Please note the chapter
"Service/Repair" with regard to this.
10.2 Return
Danger of injury from aggressive
media or pollutants
- Depending on the measured medium,
this may constitute a danger to the
operator.
WARNING
- Wear suitable protective clothing
e.g. gloves, goggles.
For every return shipment, whether for recalibration,
decalcification, alteration or repair, the device must be cleaned
thoroughly and packed in a break-proof manner. A return
declaration with a detailed fault description must be added to the
defective device. If your device has come into contact with
pollutants, a declaration of decontamination is additionally
required. Appropriate templates can be found on our homepage.
Download these by accessing www.bdsensors.de or request
them by e-mail or phone:
info@bdsensors.de | Tel.: +49 (0) 92 35 98 11 0
In case of doubt regarding the fluid used, devices without a
declaration of decontamination will only be examined after
receipt of an appropriate declaration.
11. Disposal
Danger of injury from aggressive
media or pollutants
- Depending on the measured medium,
this may constitute a danger to the
operator.
WARNING
- Wear suitable protective clothing
e.g. gloves, goggles.
The device must be disposed of according to the
European Directive 2012/19/EU (waste of electrical
and electronic equipment). Waste equipment must
not be disposed of in household waste!
NOTE –
Dispose of the device properly!
12. Warranty Terms
The warranty terms are subject to the legal warranty period of 24
months, valid from the date of delivery. If the device is used
improperly, modified or damaged, we will rule out any warranty
