The new PFLOW4008 flow sensors: robust, accurate

and now with an IO-Link interface

Thanks to its aluminium housing, M8 connector and one-touch connectors, Pewatron’s new series is very robust and has an IP67 rating. Internally, the sensor is built around a MEMS chip that operates based on the calorimetric principle. Both the flow and the direction of flow can be detected. The sensor is calibrated with air as standard. On request, the sensor can also be calibrated with other gases and under other environmental conditions. Measurement ranges are available from 0–2 SLPM to 0–50 SLPM with an accuracy of 1.5% FS. The PEWA4008 series is available with a linear analogue output signal as well as a digital output signal. Analogue 0.5–4.5 V or 0–10 V, digital with an RS232/RS485 interface or with IO-Link. Other customer-specific variants and options are available on request.
