Analog and digital interface in a single sensor

By Mary Page Bailey and Gerald Ondrey |

Baumer

Due to Dual Channel functionality —which enables sensor operation to be analog, digital or both simultaneously — this company’s process sensors, including the CombiLyz AFI conductivity sensor and the PP20H pressure sensor (photo), work both in conventional control topologies and digital IO-Link control environments. In process automation, an analog interface is helpful for sensor integration into existing control concepts. For sensor commissioning, IO-Link provides advantages, such as easy and fast parameterization or access to secondary data. For process control, a parallel readout of conductivity or pressure is enabled via 4–20-mA analog output. IO-Link provides access to valuable secondary data, such as process and sensor temperature. Such information can detect, for instance, unusual temperature rise in containers or pipes for predictive maintenance purposes. — Baumer MDS GmbH, Bodman-Ludwigshafen, Germany
