The stainless steel level probe IDCL 551 has been designed for hydrostatic level measurement in sewage as well as for viscous and pasty media. Basic element is a robust and high overpressure capable capacitive ceramic sensor.

The level probe with RS485 interface uses the communication protocol Modbus RTU which has found the way in industrial communication as an open protocol. The Modbus protocol is based on a master slave architecture with which up to 247 slaves can be questioned by a master – the data are transferred in binary form.
