GTM
Intuitive user guidance
According to the manufacturer, the CFA225-T series measuring amplifier in a desktop housing from GTM Testing and Metrology is currently one of the most accurate measuring amplifiers for force and torque transducers based on strain gages.
It enables on-site operation with a wide range of setting and configuration options via intuitive user guidance - also via an integrated touch display. Its accuracy class is 0.001. The target group for the strain gauge measuring amplifier includes sensor manufacturers who need to calibrate their own force and torque transducers, as well as calibration laboratories and technical universities.
The desktop version from GTM uses a bridge supply voltage of 5 V and a carrier frequency of 225 Hz. According to the manufacturer, it offers the lowest measurement uncertainty in traceability to national standards according to the current state of the art. The device in a robust metal design with carrying handles on the front has a maximum resolution of ±2,000,000, a long-term stability of <±10 ppm/a thanks to an internal inductive divider and two channels with a seven-digit display and six decimal places.
RS232, USB and Ethernet are available as standard interfaces for measured value transmission and integration into existing systems.
