Level Detection Systems and Devices

The C-Level is a non-contact, constant bin level system. It can be used with liquids, solids, corrosive or volatile materials. Sensors are mounted in the support structure of the bin and register the deflection as the weight increases and decreases. This is a 2% device.

Ramsey's Sona Tech and SonaMaster systems transmit sound waves toward the stored material and receive the reflected echoes. Material level is determined by calculating the elapsed time between sending the sound signal and receiving its echo. Sona Tech and SonaMaster systems are state-of-the-art. They provide more penetrating power because they operate in the 5-30 kHz range. That means superior performance in dusty, turbulent or steamy atmospheres.

The "BOB" not only measures up but it also measures down. The remote sensor quickly lowers a weighted bob (2ft/sec) to the surface of the product. As the bob descends, a micro-controller counts pulses from an encoder and determines the amount of cable released. Slack in the cable is detected when the bob reaches the product, causing the motor to reverse and retract the bob. The retract distance is also measured and compared for diagnostic purposes to assure that the measurement was accurate.

The "CAP" Series Capacitance level control is designed for point level monitoring of solids, fluids or slurries in bins, vessels and chutes. The CAP control detects the presence or absence of material by sensing a change in capacitance caused by the difference in dielectric constant of the vessel material and air.

The RT Series rotary level control is designed for point level monitoring of solids in bin, vessels and chutes. The RT eliminates the most common causes of rotary control failure. The de-energizing motor shuts off when material is present, rather then entering a stalled condition. This reduces wear and operating temperature and extends motor life.
