Temperature sensors TF-ATEX
1 Introduction
1.1 Intended Use
The temperature switch/sensor is used to monitor temperatures inside a tank. The TSA and TÖA temperature switches can also
be used in tube systems and cooling matrices. In this case the tube is located inside the tank.
According to EN60079-11, TS/TÖ or TF series temperature switches/sensors are simple electrical apparatuses without separate
voltage source intended for tank top installation.
When used in explosive areas this type may only be operated on intrinsically-safe circuits. When using intrinsically-safe connec-
tions they can be installed in Zone 1 (Ex group IIC) explosive areas and the temperature level be monitored in a Zone 0 environ-
ment. The intrinsically-safe power supply must be suitable for the respective zone. The limits inside these operating instructions
must be observed.
The temperature switches/sensors must not be used in highly flammable or corrosive liquids.
Before installing the temperature switch/sensor, verify the listed technical data meet the application parameters. Also observe
the applicable requirements of EN60079-14.
Further check if all contents are complete.
Please note the specific values of the temperature switches/levels when connecting and the correct version when ordering spare
parts.
1.2 Layout and Functionality
1.2.1 Layout TF-M-Pt100/TF-E-Pt100 temperature sensor
Type TF temperature sensors use a Pt100 temperature sensor to generate a temperature-dependent resistance signal. The Pt100
sensor is installed at the lowest point of the sensor tube to always ensure sufficient contact with the medium being measured.
1.2.2 Layout TSM/TSE/TSK/TSA/TÖA temperature switch
TS switches use a bi-metal switch to signal a set temperature value. Unlike the TSM standard version, the TSK and TSA/TÖA ver-
sions feature bi-metal switches with a lower hysteresis. The TSA/TÖA version is further specifically designed for installation in
tube systems and cooling matrices. The bi-metal switch is installed at the lowest point of the sensor tube to always ensure suffi-
cient contact with the medium being measured.

4 Installation and connection
4.1 Installation
The temperature switch/sensor comes fully assembled and can be mounted to the tank by screw-in thread 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. Always be sure
to screw the temperature sensor/switch into the fitting thread. Sealed with an elastic sealing ring. No other sealants required.
4.2 Electrical connections
4.2.1 PA connection (potential equalisation)
CAUTION Electrostatic charge
The housings of the temperature switches/sensors must be connected to the tank via ex-
ternal PA connection!
Ensure the temperature switches/sensors are adequately earthed (minimum conductor
cross-section 4mm2).
Particularly also observe the requirements of EN 60079-14.
Depending on the version the temperature switches/sensors have an external PA connection. This is identified by the
decal shown on the left. The connection uses an M4 thread. The PA cable for potential equalisation between the temper-
ature switch/sensor and the tank is not included with this version and must be supplied and installed by the customer.

Temperature sensors TF-ATEX
4.2.2 Intrinsically-safe connection
CAUTION Explosion hazard due to prohibited electrical connection data
Prohibited electrical connection data can cause an explosive gas mixture to ignite.
In areas with explosive gas atmospheres the temperature switches/sensors may only be
operated with an intrinsically-safe power supply. The power supply must be suitable for
the respective zone. The limits specified in these operating instructions must be ob-
served and must not exceeded, even with two separate intrinsically-safe power supplies.
Ensure the limits will not be exceeded, even in the event of a fault, e.g. accidental series
or parallel connection.
Please observe the relevant safety requirements, e.g. EN60079-11 and EN60079-14, when
installing and operating intrinsically-safe equipment.
According to EN60079-11 the components for level and temperature monitoring are simple electrical equipment and to be con-
sidered purely ohmic circuits. They may only be operated with an type-tested controller with an intrinsically-safe circuit.
Please refer to chapter "Technical Data" for the pin assignment and technical data. Please refer to the chart below for the tech-
nical parameters and the approved limits (Ui , li , Ci , Li , and Pi) for intrinsically-safe operation:
UiliCiLiPi
Temperature contact 30V 50mA negligible negligible 100 mW
Temperature sensor 30V 50mA negligible negligible 100 mW
Pt100 temperature
sensor
30V 50mA negligible negligible 100 mW
Remarks about the Pt100 connection
Operate the Pt100 with the respective EX approved RTD converter or a separating barrier with RTD input, suitable for EX. The
measuring current Ic must be ≤1mA to prevent excessive self-heating, which will cause measuring errors.

5 Operation and control
DANGER Toxic, acidic gases/liquids
Protect yourself from toxic, corrosive gasses/liquids when performing any type of work.
Wear appropriate protective equipment.
DANGER Dangerous electrostatic charge (explosion hazard)
The equipment may only be used where normal operating conditions do not produce
frequent flammable, electrostatic discharge.
Sparking
Incendive electrostatic charges may occur when cleaning plastic housing parts and
decals (e.g. with a dry cloth or compressed air). The sparks this produces could ignite
flammable, explosive atmospheres.
Always clean plastic housing parts and decals with a damp cloth!
DANGER Impact
Strong blows to the housing can produce sparks, which can ignite an EX atmosphere.
Protect the equipment from external impact. Damaged housing parts must be replaced
immediately.
CAUTION Explosion hazard due to prohibited electrical connection data
Prohibited electrical connection data can cause an explosive gas mixture to ignite.
In areas with explosive gas atmospheres the temperature switches/sensors may only be
operated with an intrinsically-safe power supply. The power supply must be suitable for
the respective zone. The limits specified in these operating instructions must be ob-
served and must not be exceeded.
Please observe the relevant safety requirements, e.g. EN60079-11 and EN60079-14, when
installing and operating intrinsically-safe equipment.
NOTICE
The device must not be operated beyond its specifications.
Before startup, check
– The electrical connections are undamaged and correctly installed,
– The temperature switch/sensor is connected intrinsically-safe (proof of intrinsic safety e.g. according to EN60079-14),
– No parts have been removed from the temperature switch/sensor,
– Protection and monitoring devices are installed and functional (e.g. switch amplifier),
– The ambient parameters and technical specifications (e.g. Ui, li) are met,
– Electrical connections are securely connected and the monitoring devices are connected and set as prescribed,
– Precautions have been taken,
– the connectors are closed and the cable glands are properly sealed,
– The requirements of EN60079-14 are met,
– The earth is proper and functional.
