Cynergy3 Industry Applications for the Chemical Process Sector

The Chemical Processing Industry offers specific challenges for sensor design and development as the environment in which the sensor is used may be corrosive. There may be specific requirements for materials that can be used and measures that need to be taken to ensure accurate, durable performance.

Our sensors are used in a variety of environments where chemical exposure is necessary including provision of Level Sensors and Float Switches for industrial inkjet printing, and numerous Level and Flow Sensor applications to measure movement and storage of chemical liquids during industrial processing.
