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 apply-
ing 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.
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 Sensors Heavy Duty Compact model: SEN-86../87..
Operating Instructions
4. Regulation Use
Pressure sensors transmit the mechanical pressure signal into an electrical
output signal. The media’s which are in contact with the instrument should have
no effects on the instrument materials used. Do not use standard units in
hazardous areas and for oxygen applications.

5. Operating Principle
KOBOLD Pressure sensors model SEN-86 are inexpensive pressure sensors
with thick film ceramic pressure element. With their accuracy, reliability and
compact design, they are perfectly suitable for OEM applications in medium to
high quantities.
The materials and technology used make these pressure sensors insensitive to
chemically aggressive media and mechanical load.
Particularly hydraulics systems with their high and fast pressure peaks are thus
preferred applications.
6. Mechanical Connection and Putting to Operation
The place where pressure is taken should be prepared according the following
specifications for the screw-in threads.
For sealing, please use sealing discs acc. DIN 16258 or profile washers. The
maximum initial tension depends on the material, the shape of the used sealing
and the mechanical connection of the pressure sensor.
There should be no vibrations and/or no radiation of heat near the mounting
position of the sensors. Please pay attention that the given technical data’s are
not exceeded. After the mechanical and electrical connection the sensor works
immediately.

7. Electrical Connection
Ensure that the power is disconnected during connection of the cable.
The electrical connection is made either via plug and pin or by cable.
The exact wiring scheme is shown on the sketches hereafter or at the type
plate of your sensor.
Meaning of the different connector markings
UB+ positive pole of the supply voltage
OV negative pole of the supply voltage
S+ positive pole of the output signal
S- negative pole of the output signal
Shielding Cable protection enclosure-earth
The sensor can be supplied with a non stabilised DC source with the given volt-
age range. The minimum supply voltage for pressure sensors with current output
should be the minimum UB plus the minimum voltage, which is needed for the
external indicator:
Current output
2-wire system 3-wire system
Output signal 4...20 mA 0...20 mA
Supply voltage UB= 15 ... 32 VDC
Permissible load RA[Ohm] = (UB[V] - 15 V) / 0,02 A
