2. Note

Please read these operating instructions before unpacking and putting the unit
into operation. Follow the instructions precisely as described herein.
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.

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:

 Pressure Sensor with Ceramic Instrument model: SEN-9601
 Operating Instructions

4. Regulation Use

Any use of the Pressure Sensor with Ceramic Sensor Element, model: SEN­9601, 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.

Caution!
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.

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- The product warranty is no longer valid in case of non-authorized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

The pressure transmitter turns the input pressure into an output electrical signal.
The electrical signal changes in proportion to the input pressure level.

5. General

The KOBOLD SEN-96 Standard model is an electronic transmitter with ceramic
sensor for air, industrial, technical gases and water and oil, designed to be
installed in gas distribution plants, on bottles, on refrigerators, on compressors,
on vacuum pumps and hydraulics and water high pressure plants.

6. 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 (20…30 Nm). The correct torque depends on the type of
process connection and the type of seal used (form and material).
As for those process connections with a cylindrical thread (Gas-Metric), a head
gasket compatible with the measurement gas or fluid should be used.
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.

The transmitter metal case should always be connected to ground (GND) through
the process connection thread in order to protect the sensor from disturbances
due to electromagnetic fields or electrostatic charges.
The sensor can also be connected via the ground connection to the system
ground.
