This block-style capacitive smart level sensor with IO-Link is suitable for applications with highly conductive fluids such as acids and bases. It uses smart level 50 technology to compensate for foam and deposit build-up. The IO-Link interface enables expanded application and setting options. IO-Link’s automatic parameter settings allow users to see the upper and lower hysteresis values for easy and precise adjustments that aren’t possible with a potentiometer. Once unplugged, the sensor goes into standard I/O mode (SIO). This capacitive sensor detects fluid levels through nonmetallic containers up to 10 mm thick.
