3. Safety
3.1 Explanation of symbols
WARNING!
... indicates a potentially dangerous situation that can result
in serious injury or death, if not avoided.
CAUTION!
... indicates a potentially dangerous situation that can result
in light injuries or damage to property or the environment, if
not avoided.
DANGER!
... identies hazards caused by electrical power. Should the
safety instructions not be observed, there is a risk of serious
or fatal injury.
WARNING!
... indicates a potentially dangerous situation that can result
in burns, caused by hot surfaces or liquids, if not avoided.
Information
... points out useful tips, recommendations and information
for ecient and trouble-free operation.
3.2 Intended use
The model TFT35 compact temperature transmitter is used for
temperature measurement of liquid and gaseous media in the range
-50 ... +200 °C (-58 ... +392 °F).
It can be used for pressures up to 40 bar. All electrical components are
protected against splash water and are designed to withstand vibration.

The integrated thermowell with xed threaded connection or adjustable
compression tting enables direct installation into the process. All wetted
parts and also the case are from stainless steel.
The case and the exchangeable measuring insert are screwed together
using a knurled nut.This enables the exchange of the measuring insert
without having to remove the instrument from the process.
Through the integrated coupler connector, simple installation of the
transmitter is ensured.
The integrated electronics convert the temperature-dependent
resistance signal of the measuring element into a linear unit signal. For
the signal outputs, 4 ... 20 mA, 0 ... 10 V and also 0.5 ... 4.5 V ratiometric
are available.
This instrument is not permitted to be used in hazardous areas!
The instrument has been designed and built solely for the intended use
described here, and may only be used accordingly.
The technical specications contained in these operating instructions
must be observed. Improper handling or operation of the instrument
outside of its technical specications requires the instrument to be taken
out of service immediately and inspected by an authorised WIKA service
engineer.
The manufacturer shall not be liable for claims of any type based on
operation contrary to the intended use.
