Low Noise Inline Amplifier
User Selectable Gain Settings
Small Rugged Package
Includes Auto-Zero Function
The Model 140 is a remote in-line DC amplifier designed to be used with bridgetype mV output transducers. The amplifier features five user selectable gain settings with a gain accuracy of ±0.5% and offers a wide bandwidth to 100kHz. The model 140 offers a unique auto-zero function (patent pending) that allows the operator to zero the transducer 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 sensor for a more accurate measurement.
