The 505-2400 Series Continuous ultrasonic level transmitter provides superior performance previously not available in a two-wire ultrasonic transmitter with a range of up to 30 feet. The compact transducer design allows mounting in any 2-inch nozzle. It also allows for a recessed nozzle mounting, enabling the user to measure from the very top of the tank. The automatic profiling (tank mapping) eliminates interfering signals from agitators and other obstructions in the vessel without the need to empty the vessel. The level measurement output is a 4-20 mA current signal. Ideal for use in Explosion-hazard areas, you can configure the unit using the integral switches, without power, at the vessel or in the shop. Unit can be set up before placing it in a hazardous area.
Operation: The electronics generate a signal which is sent to the transducer. The transducer transforms this electronic signal into an ultrasonic sound pulse that is directed toward the liquid. When the pulse reaches the liquid level, it is reflected back to the transducer. This received echo is converted back to an electronic signal that is sent to the microprocessor. The microprocessor then calculates the length of travel.
