BCS DC 3 Wire Flush Block Capacitive Sensors


BCS capacitive sensors monitor and detect stack heights and levels as well as the presence of objects and content in glass, plastic or paper packages all with extreme precision. The BCS range are unaffected by dust, surface reflections or any object composition such as colour or texture. Capacitive sensors can also detect levels of solids or liquids with reliability through glass and plastic walls. This diverse series consists of high temperature and pressure ratings with stainless steel and PTFE housings for harsh environments.
