New Quad-Channel Resistive Bridge Conditioner Provides Best Channel Density / Value Per ChannelPress Release
Designed for test labs where versatility and accuracy of transducer conditioning are important, Precision Filters, Inc. announces the latest addition to the 28000 Signal Conditioner System. The 28104A Quad-Channel Resistive Bridge Conditioner provides four channels of high-density conditioning for strain gages and other non-self-generating transducers requiring a Wheatstone Bridge. Each channel offers conditioning for 1, 2 and 4 arm strain gage bridge applications. Up to 64 channels may reside in a single 7-inch rack mountable chassis or combine this card with other 28000 signal conditioning cards to meet applications with a variety of sensors. Available bridge completion resistors include 120W , 350W , 1kW or user specified values. Programmable 4 or 8 pole low-pass filters operate in either "flat" or "pulse" mode. Select from a wide range of cutoff frequency settings - Up to 204.6 kHz "filter" bandwidth or 700 kHz "wideband" bandwidth. The card provides constant voltage excitation for the bridge and the bridge is automatically balanced at your command using a ratiometric insertion derived from the excitation supply to insure stable operation. The 4096 step bipolar shunt calibration allows you to check linearity and span. A Graphical User Interface (GUI) furnishes control panels for configuration, set up,
operation and tests. A grouping of algorithms assist to compute proper gain,
gain distribution and filter cutoff frequency for best performance and system scaling of
each measurement channel. Also managed from the GUI are optional built-in self-tests and
fault diagnostics, the same tests performed at the Precision factory, to assure end-to-end
system performance and eliminate off-site calibration. Precision Filters, Inc. furnishes system solutions in signal conditioning, filters, switch matrices, data acquisition and other instrumentation. The company supplies test measurement systems to research, industrial and military markets worldwide. Contact Precision Filters, Inc., 240 Cherry Street, Ithaca,
