TEMPERATURE measurement technology based on resistance thermometers or thermocouples is widely used in many applications. To integrate them into a digitalised environment, ifm now offers an IO-Link temperature measurement module.
In most cases, temperature measurement in industrial production environments is based on two physical effects: the temperature dependence of a resistor or the thermoelectric effect (Seebeck effect). ifm now offers new IO-Link temperature measurement modules for such resistance thermometers (Pt100 and Pt1000) and thermocouples (type J and type K). The measured temperature values are then made available digitally via IO-Link to higher-level controllers.
The resistance thermometers and thermocouples are connected via four M12 connectors on the module. The resistance thermometers can be connected using 2-wire, 3-wire or 4-wire technology. The individual connections can be configured conveniently via IO-Link. The type of measuring element – Pt100, Pt100, thermocouple type J or type K – can be specified there. Depending on the measuring line, the parameters ‘cold junction offset’ and ‘zero-point calibration’ can also be set for the thermocouples. The resolution of the temperature measurement with the new module is 0.01 °C, and the accuracy over the entire measuring range is 0.3 %. With a protection rating of IP67 or IP69K, the modules can also be used in harsh industrial environments.
