Level Sensors

Process sensors capture pressure, temperature, and flow in production equipment. Their readings feed PLCs and process control systems, which use them to drive valves, pumps, and heating circuits.

Pressure sensors come as gauge, absolute, or differential versions and handle process, hydraulic, level, and filter monitoring in chemistry, pharma, and plant engineering.

Temperature sensors range from Pt100 probes through thermocouples to infrared heads and cover -200 to over 1000 °C in process, food, pharma, and HVAC applications.

Flow sensors measure electromagnetically, by Coriolis, ultrasonically, or thermally depending on the medium. Typical environments: water utilities, chemical lines, district heating, and plant-wide compressed-air monitoring.

Depending on environment, hygienic design, ATEX approval, or high-temperature construction is required. Dominant interfaces are 4…20 mA, HART, and increasingly IO-Link.
