Flow and pressure sensors with IO-Link output

Developed in repsonse to the trend for increased monitoring and diagnositcs, SFAW is the first flow sensor from Festo for sensing liquid media and the SPAU is a new modular system designed for the monitoring of pressure and vacuum in process and factory automation applications.   

The sensors are available with IO-Link output options and the modular electrical output concept makes them flexible and open, allowing simple integration into numerous control systems. They are also available with switchable PNP / NPN output, which means users can simplify their stock management and make cost savings associated with reduced warehousing.

“IO-Link is increasingly being used in the UK for point-to-point serial communication protocol to communicate with sensors and/or actuators in new automation systems,” says Steve Sands, product manager at Festo.  “Remote maintenance and parameterisation, as well as simpler sensor change, are made possible via IO-Link, which means set-up and changes can be made faster and with less opportunity for errors.”

The new pressure and flow sensors have an intuitive menu guidance with a large high-contrast back-lit blue/white/red LCD so users can clearly check the flow and pressure of their systems. 

The are suitable for monitoring the flow rate, consumption and, optionally, temperature of liquid in cooling circuits, for example in welding guns in the automotive industry or in front-end applications in the semiconductor and other electronics industries. The sensors offer two flow measurement ranges of 1.8 to 32L/min and 5 to 100L/min. Temperature of liquid media can be measured from 0 to +90°C.

The new SPAU sensor for pressure measurement, monitoring and sensing is designed to keep pressure levels under control, ensuring greater productivity and process reliability as well as faster system commissioning.  Pressure indication, pressure switch outputs and analogue value output are all possible in one device and the sensor can reliably measure from 0 – 16 bar. It has a wide range of functions for non-corrosive gases including network, regulator and vacuum monitoring, leak tests and object detection.  

The sensors are quick and easy to mount in all installation scenarios. The modular concept enables the sensor and connections to be purchased separately, ensuring maximum flexibility during assembly – screw, flange and tubing connection options are available. In addition, the sensor can be changed quickly without the need for specialist tools, minimising downtime.

Both the SFAW and SPAU sensors are sealed to IP65 making them suitable for use in harsh process environments.
