Delavan Versa-Cap Integral 450 or Remote 460 Level Transmitter

Delavan Versa-Cap Integral is a versatile R.F. Capacitance Level Transmitter for liquids, slurries, and bulk solid applications. The sensing probe is energized with an R.F. (radio frequency) signal of approximately 2 mHz. When the process material level changes, a change in capacitance occurs resulting in a very small change in frequency, which is converted to an accurate level reading for measurement and control.

Dela-Cal, Delavan’s unique auto-calibration feature, offered only in the microprocessor-based Versa-Cap system, allows the unit to be calibrated to the process material with only one level change, 2% of span or greater.

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. A keypad and an 8-character display ease calibration and allow the user to modify relay control, dead-band, fail-safe, and time delay settings.
