Product Details:
Singer Gertsch 400 Hz decade synchro resolver bridge. Combines the functions of a decade synchro bridge and a decade resolver bridge into a single unit. A front panel switch changes the unit from one mode of operation to the other. The units are designed for testing control transmitters, differentials (rotors), and torque transmitters as components or for simulating an incremental control transformer in a servo loop. Because of the low output impedance, the bridge is essentially insensitive to pickup and loading errors. The high input impedance allows an actual load to be connected in parallel with the bridge input, providing a test of the component under actual load conditions. Operation consists of setting in the desired angle. No warm-up, no pre-use calibration. The unit is essentially a decade resolver bridge. In the synchro mode, the three-wire input is converted to two voltage signals in a scott-tee transformer arrangement. After conversion, the voltage comparator operates in the same manner as in the resolver mode. Decade synchro / resolver standards combine the functions of a decade synchro standard and a decade resolver standard into a single unit. A front panel switch changes the unit from one mode to another. In system tests, the standard may be used to introduce accurately known inputs for testing auto pilots, aircraft indicators, etc. This technique can also be used to check the response of a servo loop. In component tests, the standard may be used to transmit precise angular data to the test component. As a synchro standard, the unit may be used to test CDX'S, CT'S, TDX'S, TDR'S and TR'S. As a resolver standard, the unit may be used to test RD's and RC's.Dimensions: 15"D x 19"W x 5.25"HOriginally sold for $5,510. Our price...
