With IO-Link, the LDL family can provide:
Using IO-Link, the resolution of the conductivity value is the same throughout the measuring range. This is especially important when using the inductive (toroidal) version. A typical CIP process uses chemicals with high conductivity and rinse water with low conductivity. When using an analog output, the signal is spread out over a greater range, reducing the ability to detect small changes in conductivity. This can lead to residual amounts of chemicals going undetected in rinse water or products.
