MEAS Remote In-Line DC Amplifier
|Measurement Specialties (also commonly referred to as Meas Spec or MEAS) has just released to production the Model 140 remote in-line DC Amplifier. Designed to be used with bridge-type mV output Transducers, the Amplifier features 5 user selectable gain settings with a gain accuracy of +/-0.5 % and a wide bandwidth to 100 kHz. The Model 140 offers a unique auto-zero function (patent pending) that allows the operator to zero the Transducer offset voltage to within +/-1.5 mV. This may be achieved remotely or by pressing the on-board push button at the user's command, prior to the taking of data. This feature ensures a more accurate measurement as it removes any offset drift from the sensor. The Model 140 operates from 5 through 30 VDC excitation and can attain a zero output of +/-1.5 mV after auto-zero actuation.
Weighing only 33 grams, this small device is contained in a rugged, anodized aluminum housing that is sealed against humidity and can operate from -20 to +70 degC. Combine this with reverse polarity protection and low noise, you have a remote in-line Amplifier well suited for applications involving pressure / level indication, static acceleration testing, load monitoring and strain measurement. Ease of installation is ensured as both the Input and Output are commonly-found Binder Connectors.
