142A 1/4 bridge

The Model 142A is a remote in-line strain gage amplifier designed to be used with ¼ bridge strain gauge instruments. The amplifier features five user selectable gain settings with a gain accuracy of ±0.5% and offers a wide bandwidth to 100kHz. The model 142A offers a unique patented autozero function that allows the operator to zero the offset voltage to within ±1.5mV either remotely or by pressing the on-board push button at the user’s command, usually right before the taking of data. This feature removes any offset drift from the strain gauge for a more accurate measurement
