Principal of Operation Details

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.

Flow / No Flow
  • When the velocity of the process media is low or nonexistent, less thermal energy (heat) is dissipated from the heated sensor. As the velocity increases the amount of energy dissipated by the process media increases, thereby increasing the Thermal Signal.

    The Thermal Signal is smallest (left-most LED illuminated) in a no-flow state and increases (LED moves to the right) as flow increases.

Liquid Level
  • Air and other gases do not dissipate heat as well as liquids. Therefore, the Thermal Signal is smallest when in a process that does not dissipate heat well (air dissipates heat slower than water).

    The Thermal Signal is smallest (left-most LED illuminated) in a dry, motionless state and increases as the fluid covers the sensor.

Liquid Level / Interface
  • The CLASSIC 800 can be setup to detect the difference between most liquids if there Interface is very little or no velocity and each material has a unique thermal property (for example oil and water in a knockout tank).
