Transmission Dynamics have developed a novel, wireless Temperature Telemetry Transmitter which measures 42x27x11 mm. The transmitter is a fully autonomous wireless system, which contains a Bluetooth transmitter, battery, and microprocessor. To use the system, simply solder the temperature probe (PRT or thermocouple) and turn on the receiver unit.
The range of the transmitter is ca. 10/30m. Ideal applications include measurements on rotating machinery, such as bearings, gearboxes, and shafts. The transmitter can be programmed to transmit data at the requested sampling interval and has a typical battery life of upto 3 years.
