Delavan Captrol Integral 500

 Delavan Process Instrumentation manufactures products including solid and liquid point level and continuous level measurement. Delavan is a well-established company with a large customer base in a wide range of industries. Technologies include ultrasonic, capacitance, and microwave all of which complement and integrate with the L & J product offering.

Delavan has a proven track record of providing solutions to both bulk solids and liquids handling. Applications include wood chips, bailer, insulation products, coal handling paper/pulp production, petrochemical, and pharmaceuticals.




Delavan’s Captrol 500 is a cost-effective Microcontroller Based R.F. Capacitance On/Off Switch used in powder bulk solid and liquid applications.

“One-Touch” Button Calibration
With the utilization of our Microcontroller and Delavan’s unique Auto-Cal algorithm, calibration is accomplished with a momentary touch of a button. No special tools, complicated procedures, or valuable time is needed.

Principle of Operation
The Captrol 500 Microcontroller Based Point Level Switch consists of solid-state electronics mounted in a cast-aluminum explosion-proof enclosure. The rugged sensing element utilizes a driven guard designed to eliminate the effects of material build-up or coatings that may cause false signals.

     Another Article:

The sensing element’s “active” section is energized with an R.F. (Radio Frequency) signal approximately 2mHz. When the process level changes, a change in capacitance occurs resulting in a change in frequency. This change in frequency is compared to a preset value and after amplification, the signal is used to actuate a relay.
