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.

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:

 Electronic Temperature Sensor, model: TDA
 Operating instruction

4. Regulated Use

Any use of the Electronic Temperature Sensor, model: TDA which exceeds the
manufacturer’s specifications may invalidate its warranty. Therefore any resulting
damage is not the responsibility of the manufacturer. The user assumes all risk
for such usage. The application specifications include the installation, start-up
and service requirements specified by the manufacturer.

5. Operating Principle

The KOBOLD Model TDA temperature sensor is used for economical measuring
and monitoring of temperature. It can be used for any application in which
temperatures must be monitored with great accuracy.

The sensor element is a semiconductor that outputs a digital signal to the
electronic analyser in 0,5°C steps. The measured values are shown on a 3-place
LED display. The analogue output can be adjusted as required with the
measuring range.

6. Mechanical Connection

Before installation:

 Make sure the maximum operating pressure and maximum service

temperature for this instrument are not exceeded.

Installation:

 This device is installed in a matching sleeve. Use sealing tape (i.e. Teflon tape)

or a flat gasket to seal the threaded connections.

 The mounting position should be selected so that the sensor tip is always

immersed in the liquid being monitored, thus ensuring optimal heat exchange
between the liquid and the temperature sensor.

 Note that deposits that build up on the senor tip or dirty liquids can have an

insulating effect and cause invalid measurements.

 Whenever possible, after the mechanical installation is complete, the joint at

the threaded connector and the supply piping should be checked to ensure
that it is tight and does not leak.

7. Electrical Connection

Caution! Be sure that the supply voltage of your system is the same
as that specified on the device nameplate.

 Make sure that the electrical supply lines are de-energized.
 Make the connection using a PVC cable or the M 12x1 connector socket, as

shown in the accompanying diagram.

 Appropriate connectors with different cable lengths are optionally available.

Important! The instrument electronics may be damaged if the
connectors are assigned incorrectly.
