Title:Low Cost Instrumentation For Ultrasonic Measurements
Author Name:Apurva Y. Gandole, K. Omkar S. Ghatpande and Y.B.Gandole
Synopsis:
Low cost Instrumentation for ultrasonic velocity and attenuation measurements in liquids and solids is described in this paper. 1--10 MHz pulse generator is assembled using CMOS integrated circuits having pulse width of 2 to 60 microseconds. The wideband receiver is developed by using the Wideband Low Distortion, High Gain Operational Amplifier (OPA 643). The gain and bandwidth of the receiver are 50 dB and 10 MHz respectively. Transit time measurement has been performed by using the NI-LABVIEW and Multifunction I/O card NI-USB-6212. The system is found suitable, accurate and versatile for ultrasonic velocity and attenuation measurements.
