Strain-Gage Input Channel
10.1 Features
The Strain-Gage Input channel provides a DC excitation voltage to and accepts
millivolt signals from strain-gage transducers. These millivolt signals are digitized,
converted into engineering units, and placed into the track, peak and valley data
values of the channel. Setup and calibration of the channel can be made manu-
ally through the SETUP mode or automatically if the transducers are equipped
with
Signature Calibration
. See “What is Signature Calibration?” on page 13.
The analog-to-digital converter input circuit, features adjustable digital, low-pass
filtering, 12- to 18-bit resolution (depending on the filter setting) and has several
different mV/V input ranges. These many input ranges allow ±50,000 count reso-
lution (at the slowest filter setting) across a wide variety of mV/V input ranges.
Three methods of calibrating the Strain-Gage Input channel to the transducer are
available: known-load calibration, shunt calibration and mV/V calibration. The
benefits of each are discussed in “
Two rear panel control inputs can be field-configured for such functions as remote
tare, disabling peak/valley detection and clearing the peak/valley values. A volt-
age or current digital-to-analog (DAC) output is also available as an option.
Many diagnostic functions are performed automatically to insure correct wiring
and operation of the transducer.
