Conductivity sensor for CIP monitoring

September 2020 Sensors & Transducers

The LDL200 from ifm electronic is designed to be used in cleaning processes (CIP) in the food industry. It detects the concentration of cleaning agents and checks the rinsing water for residues and for product validation.

Precise, fast and reliable measurements during the process help to improve plant availability and optimise cleaning cycles. The benefits are reduced amount of cleaning agents required, lower energy consumption and lower water consumption during rinsing, resulting in considerable cost savings. Other benefits include:

• Reduced inaccuracies associated with a time-based cleaning process.

• Improve process performance with flexible measurement points.

• Compact, high-quality sensor design prevents failures and unplanned downtime.

The device has proved popular because of its compact design and connection. Just one M12-connector is sufficient to provide loss-free data transfer of the conductivity and medium temperature values by IO-Link. Thanks to its high measurement dynamics the LDL200 accurately monitors if wash fluid is still in the pipe or if clean water is present. And because this is done so quickly you save on resources. In other words: the cleaning process is shortened and machine availability is increased.

Parameters can be set automatically using IO-Link. Applications are found in breweries, dairies and other food manufacturing plants.
