CTP4/8-Rotate for high dynamic measurement on wheels or rotors
CTP8-Rotate is a programmable 4- or 8-channel telemetry system that is specifically designed to be mounted on rotating wheels, rims or rotors of helicopters. The following sensors can be connected: strain gauge sensors (STG) as a full-, half-and quarter-bridge, thermocouple type K to 1000°C, ICP sensors and voltage signals + /-5V or + /-10V. All sensor modules are software programmable via LAN-Adapter and integrated WEB-Interface which enables easy access from PC or Notebook.
The measured signals of the rotating transmitter are transferred by radio transmission to a stationary receiver (decoder) inside the vehicle and available as 8 x +/10V analogue outputs via BNC sockets or as digital signal output by a PCM-LAN-IP interface. To avoid any signal interferences during transmission the decoder is equipped with an advanced diversity- or quad-rf-receiver. A simultaneously and synchronic data transmission of all channels is ensured under all conditions. The maximum distance between transmitter and receiving antenna is approx. 10-20 m (30-60 feet) - depending on the application.
By the use of advanced rf-transmission technologies the CTP4/8-Rotate Telemetry enables an extreme high-speed signal transfer of up to 5Mbit/s. As a result of this, all channel can be transferred with an analogue bandwidth of up to 0..12kHz which is most important in measurements of dynamic torque and vibrations.
