Telemetry TT20

Telemetry TT20 is the 7-channel telemetry system. It is used 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. TT20 includes a telemetry assembly and a decoder. The rotor of the telemetry assembly is fitted to the end of the rotating shaft and electrically connected directly to the strain gauges. The stator housing is supported on the rotor by two ball bearings and electrically connected to the decoder. The excitation voltage for the strain gauges and rotating electronics is inductively coupled to the rotor. There is the built-in rotation speed measuring system.

Special features 7-channel contactless transmission of measuring signals Digital bridge balancing Digital measuring range setting Additional channel for nominal output signal, zero signal and excitation voltage control High-level analog output signal Inductive power supply The built-in rotation speed measuring system
