Model 6014, 8-Channel Accelerometer Amplifier-Filter-Digitizer





Features

  • AC or DC coupled inputs, IEPE transducers
  • 2 to 20 mA current excitation
  • Gains 1 to 5,000 with 0.05% accuracy
  • Automatic zero & gain calibration
  • Four pole, low pass filter
  • Up to 10 kS/s per channel with 16-bit resolution
  • Two alarms with programmable upper & lower limits

Description

The 6014 input module has eight channels, each with AC or DC coupled programmable gain instrumentation amplifier, low pass filter and sample and hold. The high level outputs are multiplexed and digitized to 16 bits then output to the 6000 data bus. Each channel has a 2-20 mA current source for powering low impedance, voltage mode charge transducers.

The 6014 is used with low impedance, piezoelectric transducers and low or high-level voltage signals. The input may be AC coupled for amplifying dynamic signals without the DC signal component or by changing jumpers it becomes a DC-coupled instrumentation amplifier.

Voltage substitution is provided for channel gain calibration utilizing 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 calibration. Using Pacific's PI660 software zero and gain calibration and correction are automatic.

A four-pole, low-pass filter uses easily changed plug-in modules to set bandwidth. Either the wideband or filtered output may be digitized and sent to the 6000 data bus. Two programmable alarms with upper and lower limits are checked each time the outputs are digitized. The high-level analog outputs provide a means to independently monitor or record each channel.
