DESCRIPTION

Model 5821, is a new, economical channel module for 5800 transient recorders used to acquire and record high-frequency transducer signals. It conditions, amplifies, filters, digitizes and stores data from strain gage, bridge, thermocouple, potentiometer and piezoelectric or other similar voltage output transducers. Synchronized sampling of channels in multiple systems provides excellent time correlation between channels and to external events.

Each channel has two inputs. One has excitation and amplification for low-level voltage output transducers such as strain gages. The other is AC coupled with current excitation for transducers with built-in electronics. Signal conditioning includes programmable voltage excitation and completion for ¼, ½ and full bridge transducers, automatic balance, four-step shunt calibration, programmable gain and a four frequency, eight-pole filter. Channel module 5821 is not hardened for high G applications like the 584x models and has fewer features. Voltage substitution calibration with internal precision reference is optional.
