2 Note
Please read these operating instructions before unpacking and putting the unit in
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 correspond 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.
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:
 Device model: TTL
4 Regulation Use
The temperature sensors of series TTL are suitable for all applications where
processes involving fluids, solid bodies or materials, or gases, require temperature
recording and measurement. Our temperature sensors are suitable for use in the
following industrial areas: chemicals, petrochemicals, water, feed, food, sanitary,
etc.
Any use of the Temperature Sensor, model: TTL, 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 Operating Principle
Thermocouples use the Seebeck effect, state that a voltage is generated at the
point of contact of two different metals.
Electrical conductors of different metals or metal alloys are connected by
punctiform welding. A thermal e.m.f. is generated at the free ends (point of
connection) by heating this junction ( measuring junction ). The free ends are
extended to a point with know temperature (reference junction) by means of
compensating leads. The temperature difference between measuring junction is
measured with thermocouples.
6 Use in hazardous Areas
6.1 Area of validity
These security instructions apply to TTL Series temperature sensors and their
accessories for use in explosion-proof atmospheres conform to CE certificate
LOM 08ATEX2015 X
6.2 Guidelines
The TTL Series temperature measuring instruments work according to the
Seebeck efect. This measuring principle acts to check and measure the
temperature also in Ex areas.
TTL devices can be with a standard 4 to 20 mA signal transmitter, protocol Hart,
Profibus/Fieldbus or with direct access to the sensor. They are appropriate for use
in Group IIC and Categories 1G/D Atex atmospheres.
The temperature class and/or the surface temperature relates solely to a device
operated at ambient temperature. On installation the actual temperature class for
process operation must be determined.
The inlet bushings used must conform to the certification for their type in
accordance with the directive.
The requirements of Regulation 2014/34/EU, and the applicable national
regulations for the use of measuring instruments in Ex areas, such as EN
60079-0, EN 60079-11 and other regulations relating to this certification type, must
be fulfilled.
Only qualified specialist personnel may install devices in Ex areas.

6.3 General
 When installing the sensor, it is necessary to follow all the instructions and
regulations for explosion-proof areas and the safety instructions included in
these instructions.
 TTL-SN and TTL-SA must be protected with an enclosure at least a degree of
protection IP20.
 Make sure that the details on the sensor’s type label correspond to the working
conditions for the application.
 When installing the device, make sure you do not create any mechanical
deformation as a result of solder spots or the application of mechanical force.
 Important: Make sure there is an electrical connection between the device’s
earth and the earth of the system.
 Make sure the lid is closed before putting the device into operation.
 Before re-opening the lid, remove the plug from the mains or de-energise the
device and make sure there is no danger of explosion.
6.4 Protection against E.S.D. (Electrostatic Discharge)
Temperature sensors with plastic parts that can become electrically charged bear
a warning label. Electrical charging must be avoided at all costs. Pay attention to
the following:
- Avoid rubbing the device
- Never clean the device dry
- Do not install the device near material airflows or near steam outlets
6.5 Maintenance and repairs
The instrument does not require maintenance or servicing.
Repairs must be only carried out by Kobold Mesura (manufacturer)
6.6 Storage
Measuring instruments should be protected against humidity and dust.
Storage temperature: -40ºC….+85ºC for sensors without transmitter.
Storage temperature: See manual of the corresponding transmitter.
