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.
Operating instructions, data sheet, approvals and further information via the QR
code on the device or via www.kobold.com
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 machinery directive.
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:
Resistance thermometer model: TNK
4. Regulation use
Any use of the resistance thermometer, model: TNK, 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.

5. Operation
Resistance thermometers are electric temperature measuring transducers which,
when used in conjunction with the corresponding evaluation devices, display and
regulate temperatures. They contain temperature-dependent measurement
resistors that are housed in one of the valves adapted for this purpose.
TNK resistance thermometers are specially designed for use in shipbuilding and
mechanical engineering and meet the high demands for robustness, reliability,
impact resistance, shock and vibration resistance in accordance with the
specifications set by DNV and Deutsche Bahn; particularly suitable for
temperature measurements on diesel engines.
The resistance thermometer sensor is made of brass, saltwater-resistant bronze
or stainless steel. The connecting head is made of saltwater resistant aluminium
and is available with various cable inlets. The sensor can be built onto the
machine or into the pipeline using different threaded nipples or clamp screws.
The measurement resistors can be replaced without having to remove the valve.
For more critical applications, the sensor can also be used as a dual precision
resistor.

6. Mechanical connection
Before installation:
Remove all transportation locks and ensure that there are no packaging
materials left in the unit.
Ensure that the permissible max. operating pressure and operating
temperature for the unit are not being exceeded (see technical data).
During installation:
Install the resistance thermometer in the system at zero potential.
Protect the measurement sensor from mechanical damage during the process
Seal the mounting thread or the mounting flange with appropriate sealant.
If possible, at this point, a check should be carried out after the mechanical
installation, to determine if the connecting fittings are completely sealed.
If the resistance thermometer is mounted in an exposed location, the
connecting head should be protected from exterior damage.

7. Electrical connection
Warning! Ensure that the voltage values in your system
correspond to the voltage values for the measurement unit.
The electrical connection should only be carried out by
competent staff with the relevant expertise.
Choose a suitable cable for the electrical connection:
Version TNK-...P: Cable diameter 5-10 mm
Version TNK-...M: according to DIN 89280 with internal thread M18x1.5
for cables with a cap, diameter: 8-10.5 mm
(For shipping use)
Version TNK-...M: according to VG 88812 with internal thread M18x1.5
for cables with a cap, diameter: 11.5-12.5 mm
(For military use)

12. Disposal
Note!
Avoid environmental damage caused by media-contaminated parts
Dispose of the device and packaging in an environmentally friendly
manner
Comply with applicable national and international disposal regulations and

Batteries
Batteries containing pollutants are marked with a sign consisting of a crossed-out
garbage can and the chemical symbol (Cd, Hg, Li or Pb) of the heavy metal that
is decisive for the classification as containing pollutants:
Cd1 Hg2 Pb3 Li4
1. „Cd" stands for cadmium
2. „Hg" stands for mercury
3. „Pb" stands for lead
4. „Li" stands for lithium
