Telemetry TT02
Telemetry TT02 is the 7-channel telemetry system for amplifying and contactless transmission of signals from the strain gauges mounted on the rotating machine parts to the stationary measuring unit or data acquisition system. It is suitable for measurements of various physical quantities such as strains, forces, torque, when the strain gauges technology is applied.  | Special features - 7-channel programmable transmitters
- Digital bridge balancing
- Digital measuring range setting
- Service channel for nominal output signal, zero signal and excitation voltage control
- High-level analog output signal
- Multi-channel measuring unit
- Power supply by battery or rotating transformer
