About

Manufacturer of test equipment used to test and calibrate depthsounders and transducers. Other products include acoustic targets and loran C simulators.

The DSTS-4A Depth Sounder Test Set uses digital signal processing to bring new levels of accuracy and ease of use together for your benefit. Equally at home in the engineering lab, repair shop, or production line, the DSTS-4A fills all the requirements to test and calibrate today's sophisticated depth sounders. -------------------------------------------------------------------------------- Features: Digital microprocessor control for accuracy and ease of use. Large Display lets you see all pulse parameters at a glance. External Load Jacks for specialized load requirements. Calibration Selections for feet, fathoms, and meters. Wide Frequency Range covers 2.9 to 650 kHz. Input Pulses up to 2500 Vp-p for the highest power sounders. Fish Echo mode simulates different size fish at any depth. Automatic frequency and pulse width tracking. Scope Trigger Output leads the reply pulse by 10 uS. RS-232 Option for complete control of all functions. Battery Pack Option. Rechargeable internal battery for field use. -------------------------------------------------------------------------------- More About the DSTS-4A By design, the DSTS-4A dramatically shortens the time spent repairing and calibrating sonar systems. Technicians and engineers know how important it is to view all the pertinent data on one screen. A two by twenty-four character super-twisted LCD display gives you complete information on the depth sounder under test. Data on the depth sounder under test is logically presented. The top line of the display shows the incoming pulse parameters; specifically, the frequency, pulse width, pulse period, and the pulse voltage. The second line displays the outgoing pulse parameters, frequency, width, and depth. You always know what you are measuring without reaching for a switch. And, with digital signal processing, what you see is accurate to the last digit. Depth units may be set for feet, fathoms, or meters. Calibration is based on 4800 feet per second for feet and fathoms, and 1500 meters per second for metric. Options include an RS-232 port, built-in rechargeable batteries, and a broadband balun for use with depth sounders that have balanced outputs.

NOW YOU CAN TEST: Piezoelectric transducers. Transformer coupled transducers. Magnetostrictive transducers. Check Transducers for proper operation Determine if a transducer is good or bad within seconds. Extended Frequency Range 500 Hz to over 600 KHz. Covers survey and special purpose sonar and acoustic transducers. Read transducer impedance Direct display of computed transducer impedance. Accurate Frequency Readout. Displays resonant frequency within 10 Hz. Load Reactance Indicator Display indicates reactive component of the transducer as frequency is varied. Leakage Indicator Detect leakage in the transducer and associated wiring. -------------------------------------------------------------------------------- How it Works As the frequency is varied the voltage at the attached transducer is monitored and compared to the voltage generated internally in the TT-2D. Each cycle of the waveform is sampled at three different points. The resulting voltages are converted to digital form and sent to the microprocessor. If the transducer is good these voltages will vary in a unique manner about the resonant point. Based on this information the microprocessor will compute and display the transducer’s impedance and reactance. Additionally, the DC resistance of the transducer and associated wiring are checked for continuity and leakage. -------------------------------------------------------------------------------- Using the TT-2D Connect a transducer to the xducer jack. Turn the power on and rotate the frequency controls until the LED brightness peaks, indicating a resonant point. Read the frequency and impedance. Press a button to check for continuity/leakage. If the resonant frequency is correct and no leakage is indicated the transducer and associated wiring are good. Bad transducer elements and incorrect cabling or wiring are easily diagnosed. Test cable and 9 volt battery included! -------------------------------------------------------------------------------- Please E-Mail Ray Kauffman or telephone (800) 421-2968 (within the USA) for more information on EDI's product design services. --------------------------------------------------------------------------------
