Multi-Channel Tone Burst Pulser/Receiver and A/D Device for USB
USB-UT350MT is a combination of a tone burst pulser/receiver and an analog-to-digital converter -- both of which are located in a single device for the universal serial bus (USB 2.0). This product comes in three models: 4-channel, 8-channel and 16 channel. The device generates a series of bipolar pulses with user-defined pulse frequency and pulse cycles from T connectors of a channel. The pulses are transmitted to an ultrasonic transducer, and the transducer converts the electrical excitation pulses to ultrasound which is propagated into either the tested material or air. The transducer also receives the reflected echoes from the interface and converts the ultrasound back into an electrical signal. The on-board receiver processes the signal with the user defined parameters, and the A/D converter converts analog signals into digital data at a rate of up to 50 million samples per second. In addition, the digital data is transferred to a computer’s RAM at about 40 MB per second.
Adjustable parameters include pulse frequency, pulse cycles, receiver gain, DC offset, rectifications, sampling rates, trigger source, and adjustable trigger delay. A standard scope software for MS Windows is included with the device.
One of the unique features is the on-board DSP chip from Texas Instruments. It is capable of processing data at high speeds for real-time peak detection, data compression, spray marker control, factory process control and feedback. With the on-board DSP chip, the device can run stand alone as a remote tone burst pulser/receiver and data processing system without being connected to a computer. The user can set up the parameters through the USB port and then save the parameters in the memory. The device can load the parameters automatically after the device is powered up without any control from the computer.
So USB-UT350MT can be used as a smart flaw detector (for wood, rubber and concrete) and distance measuring device (in air) with various software running at real-time. Custom software is available for your applications upon request.
USB-UT350MT can also be built with square-pulse pulser.
