Plug-In Assembly Configccralion 4331 OPTIONS 0701071 1-hp- Model 44427A 120 Ohm Strain GaugeIBridge Completion assembly and -hp-Model 444276 350 Ohm Strain GaugeIBridge Completion assembly provide bridgecompletion for resistance strain gauges and other resistive transducers such as RTD'sand pressure sensors. You can use the assemblies to provide termination for any mixtureof %, % or full bridges and can use 2 or 3-wire (plus shield) transducerconnections.Each strain gaugelbridge assembly can measure up to 10 transducers (strain gauges,RTD's, etc.) when using the internal half bridge shared by all transducers. Each3497A can hold up to five 44427A and/or 44427B assemblies and each 3498A Extender(Option 298) can hold up to 10 assemblies.Thus, using the 5 slots in a 3497A and 45 slots in 3498As (maximum which canbe used for these assemblies), you can provide up to 500 channels for transducermeasurements or up to 133 three element strain gauge rosettes. Of course, the44427AlB can be used in the same 3497A mainframe with other 3497A assembliesfor mixed measurements. For example, you could use the Option 020 thermocouplecompensation assembly in one slot and an Option 070 or 071 in another slotto generate apparent strain curves.DescriptionAs shown in Figure 109, the 44427AlB assemblies consist of a 20 channel relaycard and a terminal card. The relay card is identical to that used in Options 010 and020. The terminal card for the 120 ohm assembly (Option 070) is identical to the350 ohm assembly (Option 071) except that Option 070 uses 120 ohm bridge terminationresistors while Option 071 uses 350 ohm resistors.Artisan Technology Group - Quality Instrumentation ...
