Low Input Noise over Wide Bandwidth Offered in New Differential Amplifier from Measurement Specialties

3-channel Model 121 provides user-selectable parameters for measurement flexibility

Hampton, Va. May 2013 - Measurement Specialties (NASDAQ: MEAS), a leading global manufacturer in sensor-based measuring of pressure/force, position, vibration, temperature, humidity and fluid properties, now offers a 3-channel DC differential amplifier with an exceptionally low noise input of less than 20 µVrms. The new Model 121 enables precision measurement on up to three channels simultaneously.

Offering programmable gain up to 9,999 and user-defined output scaling, the new signal conditioner is ideal for use with bridge-type or differential output accelerometers, pressure transducers and load cells.

The unit’s low noise floor over a wide frequency bandwidth up 200 kHz makes for exceptional, accurate measurement of dynamic signals. The Model 121 is used in a variety of instrumentation lab, vibration and shock testing as well as process monitoring applications.

Full scale accuracy is ±0.5% and linearity is ±0.1%. The Model 121 also features an auto-zero function that can be initiated by the operator to maximize voltage span in the data acquisition system. Each of the amplifier’s three channels features a 9-pin D-sub connector. Input impedance is less than 1 Megohm.

User-configurable shunt calibration can be applied via an internal or external resistor to any of the four legs of the transducer under test. Default shunt value is 150 kohm.

Testing parameters of the Model 121 can be easily set from the unit’s front panel via a simple push button interface. The unit stores settings for all functions on internal memory, and will automatically restore the last session’s settings on power-up.

Weighing 8.2 lbs and constructed of durable aluminum, the unit is easily transported for use in a variety of testing environments.
