Balluff/SIE Capacitive Sensors Balluff acquired SIE Sensorik – a worldwide leader in capacitive sensors - in 2007. Balluff/SIE offers a wide variety of capacitive sensors including sensors for use in high-temperature applications, complete PTFE housings for harsh environments and miniature sensors for optimal performance and reliability in confined spaces. Balluff/SIE level detection sensors, complete with reliable smartLEVEL technology, offer easy-to-use level application performance. SmartLEVEL sensors compensate automatically for foaming, filming, and material build-ups to prevent false triggering. Setup and maintenance are simple since, in most cases, these sensors do not require a preadjustment or teach-in.
