Model 6039, 8-Channel Strain/Bridge Transducer Amplifier-Filter-Digitizer


  • Programmable input configuration, ¼, ½ & full bridge
  • Programmable voltage excitation with remote sensing
  • Additional ±12 or ±15 or 28 Volt transducer power
  • Two-step shunt & voltage substitution calibration
  • Gains 1 to 5,000 with 0.05% accuracy
  • Programmable 4, 6 or 8 pole low-pass filter
  • 6039B: Up to 10kS/s per channel with 16-bit resolution
  • 6039C: Up to 20ks/s per channel with 16-bit resolution
  • Two alarms with programmable upper & lower limits


The 6039 input module has eight channels of high performance signal-conditioning amplifier-digitizers for strain gages and bridge transducers. Each channel has programmable excitation with remote sensing, voltage and shunt calibration, programmable gain instrumentation amplifier, low pass filter and sample and hold. Outputs of the sample & hold are digitized to 16 bits then provided to the 6000 data bus. The filter is programmable providing four low-pass frequencies and wideband.

The 6039 is used with ¼ (120 and 350 Ohm s/w selectable), ½ and full bridge transducers, potentiometers and low-level voltage signals in demanding, dynamic measurement applications. It is particularly suited to strain gages and bridge transducers. A shielded eight-wire input provides independent excitation, sense, calibration and signal connections to the transducer. Excitation is programmable from 0 to 12 Volts with remote sensing providing regulated excitation at the transducer. The input connector also provides access to ±12 or ±15 or 28 Volt DC power.

Gain calibration may be done by voltage substitution using an external voltage standard. A calibration attenuator enables the voltage standard to be used on its highest accuracy ranges and has a post-attenuator output for accuracy verification. Two steps of bipolar resistive shunt calibration are provided for transducer calibration. Calibration and gain and zero correction can be automated using software such as Pacific’s PI660. Two alarms with programmable upper and lower limits are provided.
