Zweikanal-Präzisionsmessverstärker der Serie CFA225-T - GTM

Best-in-class Strain Gauge Measuring Amplifier with Outstanding Precision of 10 ppm

The new CFA225-T two-channel precision measuring amplifier with a precision class of 0.001 or 10 ppm is ideal for high-precision measurements with strain gauge full bridge-based force sensors and torque transducers. The measuring amplifiers of the CFA225-T series in a desktop housing are among the most precise strain gauge measuring amplifiers in the world, which makes them suitable for high-end stationary measuring, testing and calibration of strain gauge-based sensors.

The precision measuring amplifier CFA225-T supports and facilitates on-site operation in testing and calibration labs with diverse settings and configuration options, a user-friendly and intuitive key-based user interface, and an integrated touch display.

The two-channel high-precision measuring amplifier in a robust metal housing with carrying handles on the front features outstanding performance parameters, such as a maximum resolution of ±2,000,000, high long-term stability of <±10 ppm/a due to an internal inductive divider, and a seven-digit display with six decimal places. The carrier frequency bridge supply voltage of 5V/225 Hz offers the lowest uncertainty of measurement in traceability to national standards available today. Of course, strain gauge transducers are connected by means of 6 circuit technology. 

The precision DMS measuring amplifier CFA225-T is used both by sensor manufacturers who have to calibrate their own force or torque transducers, and in calibration labs, National Metrological Institutes (NMI) and technical universities.
