Strain / Bridge Transducer Amplifier I/O Module 6753

The 6753 is an input module with 4 channels that operates with 6700U High Speed Data Acquisition and Control System Enclosure.  The sample rate is programmable up to 40 kS/s per channel with a 24-bit resolution. Each channel provides excitation with remote sensing, voltage calibration, local or remote shunt calibration, programmable gain instrumentation amplifier and four pole low pass programmable filter.

It makes up the system used for Rocket Engine, Jet Turbine Engine, Wind Tunnel, Structural and Transient Testing environments, that demand the highest performing system on the market.

The Model 6753 is a Strain / Bridge Transducer Amplifier I/O Module. Firstly, it contains four channels of high-performance signal conditioning amplifier – digitisers for strain gauges and bridge transducers.

Digitised Output and continuous, calibrated analog output.

Secondly, the high level outputs are multiplexed and digitised to 24 bits.  Then output to the 6700 data bus.  In addition, each channel provides one continuous calibrated analog output.

Input and Excitation are Isolated

The input and excitation are isolated from the outputs, power and control interface.  Therefore, this provides the user with complete freedom to ground the input.  This avoids creating ground loops the create noise and offset errors.

Signals Used

Firstly, the 6753 is used with quarter, half and full bridge transducers.  As well as potentiometers and low level voltage signals in demanding applications such as load control. The filter is a four pole programmable filter with a cut off frequency from 10 Hz to 20 kHz.

Voltage Substitution and Transducer Calibration

Voltage substitution achieved by an external voltage standard.  This is provided for traceable gain calibration.  Internal or external shunt calibration is provided for transducer calibration.  In addition, transducer balance, zero and gain calibration are automatic.   Two programmable alarms used for each digitised output.  The high level analog outputs allows independent monitoring or recording on each channel.
