Dual Transducer for Level, Flow, Positioning and Collision Protection
April 26, 2010
The dual transducer is a non-contact acoustic wave transmitter designed with flexibility that is used for measuring level of liquids, slurries and solids with the versatility of measuring two different applications at once. The unit emits high-powered acoustic wave transmit pulses from two transducers which is reflected from the surface of the materials being measured. The reflected signals are processed using specially developed software to enhance the correct signal and reject false or spurious echoes. Advanced receiver circuitry is designed to identify and monitor low-level return signals even when noise levels are high, according to the manufacturer. The measured signals are temperature compensated to provide maximum accuracy to the outputs and display. The unit is compatible with a wide range of communications such as DeviceNet, GosHawk, HART, Profibus DP and Profibus PA, Modbus and Foundation Fieldbus. The transducer unit can be used in a number of applications including, waste water/water, mining, power stations, food, cement, plastics, grain, chemicals, paper, irrigation, and quarries.
