These operating instructions are a part of the equipment. The
manufacturer reserves the right to change performance-, spe-
cification- or technical data without prior notice. Please keep
these instructions for future reference.

1.1 Intended Use

The TF temperature sensors are used to monitor temperatures
inside a tank.
The TF temperature sensors can also be used in piping and
cooling matrices. In this case the tube is located inside the
tank. According to EN 60079-11, the TF series temperature
sensors are simple electrical apparatuses without separate
voltage source intended for tank top installation. The temper-
ature sensors must not be used in highly flammable or corros-
ive liquids. Before installing the temperature sensors, verify
the listed technical data meet the application parameters.
Also observe the applicable requirements of EN 60079-14. Fur-
ther check if all contents are complete. Observe the specific
values of the temperature sensors when establishing the con-
nection.
2 Safety instructions
The equipment must be installed by a professional familiar
with the safety requirements and risks.
Be sure to observe the safety regulations and generally applic-
able rules of technology relevant for the installation site. Pre-
vent malfunctions and avoid personal injuries and property
damage.
The operator of the system must ensure:
• Safety notices and operating instructions are available
and observed,
• The respective national accident prevention regulations
are observed,
• The permissible data and operational conditions are
maintained,
• Safety guards are used and mandatory maintenance is
performed,
• Legal regulations are observed during disposal,
• compliance with national installation regulations.

3 Transport and storage
Only transport the product inside the original packaging or a
suitable alternative.
The equipment must be protected from moisture and heat
when not in use. It must be stored in a covered, dry, dust-free
room at room temperature.
4 Installation and connection
4.1 Installation
The temperature sensor comes fully assembled and can be
mounted to the tank with a screw fitting and seal. Please be
sure to leave enough space between the tank wall and add-
ons. The maximum torque of the screw-in thread is 25 Nm.
When installing, be sure the sealing face is clean and even.
Only screw the temperature sensor into the designated
thread. Sealed with an elastic sealing ring. No other sealants
required.

4.2 Electrical Connections

Electricity is supplied via plug connectors. Please refer to the
appendix for installation dimensions, nominal voltage and
plug configuration. The switching outputs are PNP transist-
ors. The level- and temperature sensor is powered with 18 -
30 V direct voltage. The sensor connects with a cable and
standard M12 plug-in connectors.
5 Operation and control
NOTICE
The device must not be operated beyond its specifications.
Version with IO-Link interface
This unit is equipped with an IO-Link interface, which require
an IO-Link master.
The IO-Link interface allows direct access to process and dia-
gnostics data, and allows configuring the unit during opera-
tion.
The IODDs required to configure the unit is available at ht-
tps://ioddfinder.io-link.com/.
If the IO-Link interface is not being used (no master or only
used to parametrise), the temperature sensor functions as a
regular temperature sensor with 2 switching outputs. The de-
fault parameters and switching function of the switching out-
puts, however, can be parametrised via IO-Link master.

6 Maintenance
Always observe the applicable safety- and operating regula-
tions when performing any type of maintenance. Please refer
to the original operator's manual on the included CD or online
at www.buehler-technologies.com for maintenance informa-
tion.
