Ultra-Sound Operation unit Function and Applications Microprocessor controlled operation unit for goniometer in failsafe housing to control the goniometer angle and recording of detector signals, with RS232 PC interface. Benefits ▪ ▪ ▪ Function and Applications Microprocessor controlled quartzstabilised operation unit for ultrasonic transmitter and receiver. Benefits ▪ ▪ ▪ ▪ ▪ ▪
Adjustable output amplitude, 2 DIN sockets, one with 180° phaseshift, continuous and burst mode operation. 1 synchronous BNC output for delay time measurement. Input signal amplifier with 3 main amplifications and fine adjustment with one BNC-socket for oscilloscope and 4 mm sockets for XY-recorder. Overload warning LED allows adaption of ultrasound intensity to the experiment. Ideally suited for ultrasound experiments with large distances between transmitter and receiver, e.g. Doppler-effect with ultrasound. Fail-safe housing.
