PC Micro Based Data Acquisition System
PCDAS-1694
is a highly sophisticated but very easy to use data acquisition system with
unlimited applications and use. The system employs PC with Add on cards & interface
cards. The system can record, analyse, plot & save data in files for future
reference using its powerful software. Almost all physical parameters can be
measured, recorded, analysed using this system with suitable sensors. The Add
on ADC card has 16 analog single ended channels, 16 isolated digital input,
output channels & two analog output channels. The reference selection for ADC
is through software. Individual channels also can have preselected references.
The interface cards are housed in a spearate DIN Enclosure which is modular
in construction. In short this system combines speed, precision & repeatability
in low level measurements with full computation and analysis capabilities. This
system provides highly capable, yet economical solutions to process control
development, transducer measurements, production testing and signal analysis
applications.
