PF3A7*H-L, Digital Air Flow Sensor with IO-Link

Series PF3A digital flow sensor provides continuous quantitative values as well as switched digital outputs when set flow levels are measured.  When paired with an IO-Link master, measured values, settings, and device information can be accessed at an HMI screen or fieldbus networked monitoring device.  32-bit of process data include 16 bits for the measured value, 2 output bits for set points, and 2 diagnostics bits.  The PF3A is suitable for applications requiring a metered quantity of air, such as for supply confirmation, filling accumulation, or fixed supply consumption.  The oversized PF3A display has 2 screens, with main screen flow values in red or green, while the sub screen settings are shown in orange.  The display can be rotated in 90 degree increments, thereby offering better visibility during operation.  The thermal sensor is protected in a bypass flow path to reduce contact with moisture and contaminants, avoiding accuracy deterioration and damage.  The PF3A has an IP65 ingress protection rating and is both RoHS and CE compliant.
