32-channel telemetry complex for providing strain-gauge measurements during GTE tests

System Description:
Designed to work as part of GTE test stands
- design - at the end of the shaft;
- frequency range of the measured signals: 0Hz ... 20kHz;
- measurement error of not more than 0.1% (availability of relevant metrological documents);
- sampling rate - maximum 80,000 meas./sec.
- work at a frequency of rotation from 0 to 20,000 rpm;
- the number of strain gauge (dynamic) channels - not less than 32;
- the number of analog temperature channels - at least 2;
- connection of strain gauges in 1, 1/2, 1/4 bridge circuit, nominal 120 or 350 Ohms;
- the ability to programmatically change the value of the sensor supply current, depending on its rating;
- operating temperature range of the system: -20 ... + 125 0С;
- power supply of stationary equipment: 220V, 50Hz;
- the possibility of extending the resource by technical condition;
- ensuring the simultaneous operation of all channels of load cells;
- ensuring the disconnection of current from all sensors at the same time, in order to control pickups on the input wires;
- ensuring the operability of the remaining channels in the event of failure of one or more channels;
- The software provides control of the telemetry unit and performs the functions of monitoring and monitoring the status of telemetry;
- the system has a set of all necessary connecting cables;
- the system provides a high ratio of the useful signal to noise;
- the system provides protection of signals from sensors from extraneous sources of exposure (drive motors, electric welding, etc.);
- the presence of built-in means of monitoring the health of equipment, including the diagnosis of breakage of sensors and communication lines;
- the ability to dismantle telemetry and install on another shaft, while the design of the shaft end remains unchanged
