Press Release Summary:
CT Telemetry System provides measurement of strain-bridge, thermocouple or voltage variables. Up to 8 channels of data can be transmitted 500 m. System signal conditions up to 8 sensor inputs and provides wireless data transmission to fixed receiving device. All channels are simultaneously sampled; conditioned measured values are routed, via anti-aliasing filter, to 12-bit A/D converter. Dynamic range is 72 dB with signal-to-noise ratio of 70 dB.

Caesar Data Systems Introduces Telemetry System For Mobile Equipment Testing
FARMINGTON HILLS, Mich., March 4, 2002 - CAESAR Data Systems has introduced a new telemetry system for the mobile equipment component testing market.
The new CT Telemetry System offers a simple solution for measurement of strain-bridge, thermocouple or voltage variables on moving equipment. Up to 8 channels of data can be transmitted 500 meters, allowing cable-free data logging from autos and trucks, construction equipment, farm machinery, military vehicles and more.
The "CT" (compact telemetry) system is capable of signal conditioning 8 sensor inputs and providing wireless data transmission to fixed receiving device (which converts the signals to an analog voltage).
All channels are simultaneously sampled; conditioned measured values are routed, via an anti-aliasing filter, to a 12-bit A/D converter. The signals are then encoded in a PCM format and transferred to the HF transmitter as modulated variables. The transmitted data is recovered by the receiving unit and reformatted into individual analog output voltages.
The dynamic range is 72dB with a signal-to-noise ratio of approximately 70dB. Two transmitters are available; a 40 kbit with four different carrier frequencies (433.3 to 434.5 Mhz range) and a 320 kbit transmitter with one frequency (433.9 Mhz).
The "CT" system is factory-configured to customer specifications at the time of order; it can be expanded or re-configured to add channels or vary sensor inputs only by returning to the factory.
CAESAR Data Systems was founded in 1986 by a group of four engineers experienced in the field of data acquisition and analysis technology. The company today is a leading supplier of measurement systems for mobile vehicle testing.
