Principle of Operation The sensor is a magnetostrictive device consisting of a diaphragm, nickel tube, magnet, drive coil, and pickup coil. When 40kHz energy is applied to the drive coil, it causes the diaphragm to vibrate at a frequency determined by the mechanical resonant system of the sensor. Electrical energy is transferred to the pickup […]
Delavan Sonac 120 Ultrasonic Switch is a reliable level control that will sense almost any liquid. Its fail-safe features ensure positive level control in critical processes. The non-intrusive feature of its sensor permits its installation in extremely small vessels and pipes. Delavan Sonac 120 Ultrasonic Switch Principle of Operation The sensor is a magnetostrictive device […]

Description 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 […]
