INSTRUMENTATION

DSA International has an extensive inventory of field and lab equipment including spectrum analyzers, torsional analyzers, oscilloscopes,  and data collectors from Hewlett Packard, Dynamic Instruments, Tektronics, Wireless Data, Ono Sokki, Sony and others. 

Our recording systems include two Honeywell 14 channel wide band FM recorders, a 7 channel TEAC FM and an 8 channel Sony DAT cassette recorder, a Hewlett Packard multi-programmer, as well as two 16 channel high speed 16 bit PC based digital data acquisition system. DSA International has recently developed a very high speed and high dynamic range non-contacting multi-channel telemetry system for dynamic torque measurements.

We have a broad range of sensors and signal conditioning equipment for data acquisition including accelerometers, pressure sensors, non-contacting speed sensors, ultra high precision encoders, extensometers, load cells to 100,000 lbs., charge and line drive amplifiers, temperature monitors, strain gauge amplifiers and other field and laboratory test gear.

DSA International is very proud of its extensive testing facilities. We have the ability to conduct a very wide variety of mechanical tests including the following:
