Model 6152, 4-Channel Strain/Bridge Transducer Amplifier - Filter-Digitizer



Features

  • Programmable input configuration 1/4, 1/2 & full bridge
  • Programmable excitation with remote sensing
  • Shunt & voltage calibration
  • Automatic zero & balance
  • Gains 1 to 5,000 with 0.05% accuracy
  • Buffered 10 Volt analog output

Description

The 6152 input module has four channels of high performance signal-conditioning amplifiers for strain gages and bridge transducers. Each channel has programmable excitation with remote sensing, voltage calibration, local or remote shunt calibration, programmable gain instrumentation amplifier and four-pole low pass filter. Each channel provides a buffered analog output.

The 6152 is used with quarter, half and full bridge transducers, potentiometers and low-level voltage signals in demanding applications such as load control. The standard filter a four-pole or six-pole filter with programmable cutoff frequency from 4 Hz to 5 kHz in 1 Hz steps.

Voltage substitution using an external voltage standard is provided for traceable gain calibration. Internal or external shunt calibration is provided for transducer calibration. Transducer balance, zero and gain calibration are automatic by program control.
