TF with IO-Link
1 Introduction
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. Ac-
cording to EN 60079-11, the TF series temperature sensors are simple electrical apparatuses without separate voltage source in-
tended for tank top installation. The temperature sensors must not be used in highly flammable or corrosive liquids. Before in-
stalling the temperature sensors, 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. Observe the specific values of the temperature sensors
when establishing the connection.
1.2 Layout and Functionality
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.
The electronics of the TF temperature sensor converts this resistance signal into a digital IO-Link signal.
