Kayden sensors incorporate two thin-film platinum Resistance Temperature Detectors (RTDs) and a separate heater element. The Reference RTD senses the actual process condition (as temperature). Heat is applied to the Active RTD by the heater element which is controlled by the microprocessor.

The microprocessor makes continuous comparisons between the temperature readings from the Reference RTD and the Active RTD (values stored as a result of setup programming). As process conditions change, for example increased velocity in a flow application, the Reference RTD “senses” the change and the microprocessor adjusts the heater and changes the relay state if required.

The CLASSIC 800 can be setup with a narrow range to detect very low flows or very small changes in the process, or with a wider range to ignore small fluctuations.

The CLASSIC 800 series switches and transmitters are digital devices and will not require calibration. By design they cannot drift or change in any way unless they suffer physical damage. After correct setup, the CLASSIC 800 will be stable and repeatable under stable process conditions.

The CLASSIC 800 may be setup in the field by the user for flow, level or interface with air, gases, liquids or slurries. The CLASSIC 800 may be setup to display process temperature through the RCM Software while functioning as a flow, level or interface switch/transmitter.
