New Baumer PP20H and CombiLyx Sensors

Baumer’s new PP20H pressure and CombiLyz AFI conductivity sensors are the latest addition to the company’s process sensors combining a digital communication interface.

Digital communication opens many opportunities, but only sensors that reliably deliver precise measured values offer real added value by IO-Link.

The PP20H and CombiLyz AFI sensors now they offer even more interesting features such as simple and fast parameterisation even during operation. This way, secondary data like different process data output simultaneously or diagnostic data only accessible this way can be communicated from sensor to controller or even retrieved from the sensor memory, if required. Further to the digital interface, the sensors also provide one or more conventional analogue outputs for maximum user flexibility.

Dual Channel – analogue and digital interface in a single sensor

Dual Channel enables analogue as well as digital sensor operation, or both at the same time.  This way, Baumer process sensors such as conductivity sensor CombiLyz AFI and pressure sensor PP20H work both in conventional control topologies and digital IO-Link control environments.

In process automation, the proven analogue interface is helpful for sensor integration into existing control concepts. Nevertheless, in sensor commissioning, IO-Link advantages such as easy and fast parameterisation or access to secondary data are a valuable help. For process control, parallel readout of conductivity or pressure value is enabled via 4... 20 mA analogue output.

More information, more process effectiveness

IO-Link provides access to valuable secondary data: process data including sensor temperature respectively process temperature of PP20H. Such information provides interesting conclusions, e.g. unusual temperature rises in the containers or pipes. And, such data is basic for predictive maintenance.

In addition to media connectivity, CombiLyz AFI sensor delivers information on media concentration. In doing so, the medium in process and its concentration can be precisely identified. Pressure sensor PP20H delivers process pressure and ambient pressure information. Therefore, the sensor can be deployed for both absolute and relative pressure measurement.

Enhanced process efficiency thanks to fusion sensor data

IO-Link allows for mutual and bidirectional sensor communication via the controller. This way, every sensor can utilise the measured values of other sensors to solve complex measuring tasks or for optimisation of processes and production flow.

Using conductivity sensor AFI (for example), transmission of the measured temperature value can reduce response times of temperature compensation to 15 seconds or even completely circumvent them. In level detection in closed tanks, two fusion pressure sensors enable direct indication of the filling level. The head pressure sensor transmits the measured value to the pressure sensor at the tank bottom for zero-point adjustment. This way, the actual pressure is determined.
