2. Note
Please read these operating instructions before unpacking and putting the unit
into operation. Follow the instructions precisely as described herein.
The instruction manuals on our website www.kobold.com are always for currently
manufactured version of our products. Due to technical changes, the instruction
manuals available online may not always correspond to the product version you
have purchased. If you need an instruction manual that corresponds to the
purchased product version, you can request it from us free of charge by email
([email protected]) in PDF format, specifying the relevant invoice number and
serial number. If you wish, the operating instructions can also be sent to you by
post in paper form against an applicable postage fee.
The devices are only to be used, maintained and serviced by persons familiar
with these operating instructions and in accordance with local regulations
applying to Health & Safety and prevention of accidents.
When used in machines, the measuring unit should be used only when the
machines fulfil the EC-machine guidelines.
Devices with max. allowable pressure ≤200 bar:
as per PED 2014/68/EU
In acc. with Article 4 Paragraph (3), "Sound Engineering Practice", of the PED
2014/68/EU no CE mark.
The instrument safety level depends on the right choice and installation of the
instrument model and on the maintenance, procedures established by the
manufacturer.
Technicians in charge of the instrument selection, installation and maintenance
should be able to understand if the instrument conditions of use could affect its
right functioning and lead to any premature damage or breaking.
It is essential that these procedures included in the plants regulations should be
carried out by qualified staff. An improper use could be dangerous for the
instrument itself and cause damages to the staff and to the plant.
In order to choose correctly the right instrument, it is highly recommended to read
the most recent catalogue sheets available on-line at www.kobold.com

3. Instrument Inspection
Instruments are inspected before shipping and sent out in perfect condition.
Should damage to a device be visible, we recommend a thorough inspection of
the delivery packaging. In case of damage, please inform your parcel service /
forwarding agent immediately, since they are responsible for damages during
transit.
Scope of delivery:
The standard delivery includes:

5. Regulation Use
The pressure transmitter turns the input pressure into an output electrical signal.
The electrical signal changes in proportion to the input pressure level.
Any use of the Pressure Transmitter, model: SEN-98/-99, which exceeds the
manufacturer’s specification may invalidate its warranty. Therefore, any resulting
damage is not the responsibility of the manufacturer. The user assumes all risk
for such usage.
Warning!
The manufacturer disclaims all responsibility in case of damages
caused by the improper use of the product and by the non-respect of
the instructions reported in this manual.
- Follow carefully the specific safety rules in case of measuring oxygen
pressure, acetylene, inflammable or toxic gas or liquids.
- Disconnect the instruments only after depressurization of the system.
- The process fluids residuals in the disassembled instruments could
affect people, the environment and the system. It is highly
recommended to take proper precautions.
Warning!
Before installation be sure that the right instrument has been selected
following the working conditions and in particular the range, the
working temperature and the compatibility between the material used
and the process fluid.
- This manual does not concern the instruments conforming to
standard 94/9/CE (ATEX).
- The product warranty is no longer valid in case of non-authorized
modifications and of wrong use of the product.
- The user is totally responsible for the instrument installation and
maintenance.
- Handle and carefully stock the instrument used for toxic or
inflammable liquids measurement

6. Electrical Connection
The transmitter metal case should always be connected to ground through the
process connection thread in order to protect it from disturbances due to
electromagnetic fields or electrostatic charges.
If it wouldn’t be possible to do so connect the transmitter to ground through the
connector and the cable screen.

7. Installation
Before installing electrical instrument safely and securely into a plant or a system
the user should verify the instrument suitability to the plant characteristics and the
correct installation. After installation the user should verify that the instrument is
not exposed to any source of heat exceeding the established ambient limits.
Secure the instrument thread through a special key/wrench on the process
connection hexagon without grasping the case by the hands.
Secure the instrument thread through a special key/wrench on the process
connection hexagon (20…30Nm). The correct torque depends on the type of
process connection and the type of seal used (form and material).
If the connection thread is conical the instrument is tightened through a simple
screwing on the plug. In order to improve the thread tightness, it is recommended
to place a PTFE layer on the male thread.
If the instrument is equipped with a fluid diaphragm seal the connection should be
clamped on the diaphragm otherwise the calibration could be compromised.
Connector Assembling EN 175301-803 Form A
Disassemble the connectors as in fig. 1 and connect the cables as in fig. 2.
Reassemble the connector and fix it on the transmitter.
Figure 1 – Exploded view of the connector Figure 2 – Wires connection
Warning!
The IP grade according to standard EN-60529-1:1992 is guaranteed
only if the female connector equipped with a connection cable is
mounted on the instrument and all the other components are
assembled correctly.

8. Recalibration and maintenance
In models the zero and the full scale range can be adjusted as follows
(see figure 3):
- Connector disassembling (see fig. 1)
- Zero adjustment (Z)
- Span adjustment(S)
