Level and temperature measurement via one cable
April 2018, Temperature Measurement


IO-Link is a standardised and fieldbus-independent interface for automation that provides the user with point-to-point connections without complex addressing. Binary switches that used to be limited to simple switching signals of analog values have developed into smart sensors. IO-Link transmits both level and temperature parameters as digital process values via one single cable. This means that only one input port is required on the controller. This allows simple and timesaving parameter setting.

Efficient and reliable thanks to IO-Link

Thanks to IO-Link, ifm Electronic’s new temperature and level sensor continuously transmits process values and other important data such as minimum and maximum temperature, allowing level and temperature values to be transmitted via one cable. Moreover, digital measurement results are more accurate because there are no conversion losses by D/A converters or external influences like cable lengths. Devices with preset measuring ranges (analog start and end points) are no longer needed because the real process value is transmitted. This reduces stockholding requirements. Soon conventional transmitters will be a thing of the past.

Applications

Typical applications are hydraulic power packs and machine tools. The advantage of this sensor is that the combined level and temperature monitoring with only one unit reduces the required number of sensors, mounting locations, stock-keeping and installation complexity.

There are variable installation lengths for flexible installation.
