Morgan Electro Ceramics' Doppler System Flow Sensor
Morgan Electro Ceramics (MEC) will showcase its proprietary new Doppler System sensor at the ISA Expo 2005 which takes place in Chicago, IL, USA from 25-27 October this year.
The sensor uses semi-circular send-and-receive piezoelectric ceramic (PZT) crystals within a circular compact stainless steel housing. This single enclosure eliminates the need for separate send-and-receive sensors and provides a sensitive, simple and low cost solution for fluid sensor applications.
This innovative solution is accomplished through the use of semi-circular PZT crystals which maximise the radiating surface area in the circular housing and, by optimising '-wave' and 'shear wave mode change' principles, minimise crosstalk. Preliminary tests indicate minus 65dB of crosstalk. The sensor is available to accommodate the customer's operating frequency, sealing and packaging requirements.
MEC's piezoelectric ceramics allow for the conversion pressure and vibration into electrical energy, making it ideal for accelerometers, sensors, flowmeters, level detectors and hydrophones.
