　　Applications: Pressure & Level Indication, Static Acceleration Testing, Instrumentation Labs, Load Monitoring, Strain Measurement

　　Description: The Model 140 is a remote in-line DC amplifier designed to be used with bridge-type 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.

　　Features:

　　Low Noise In-Line Amplifier
　　x10, x25, x50, x100 & x200 Gain Settings
　　Small Rugged Package
　　±1.5mV Auto-Zero Function (Patent Pending)
　　Wide Bandwidth to 100kHz 
　　5-30Vdc Excitation Voltage
　　-20 to +70°C Operating Range

　　典型應用: 壓力和液位顯示，靜態加速度測試，實驗室，負載監控，應變測量

　　產品描述:
