This telemetry system is composed of transmitter DT-041T and receiver DT-041R-1. Since the system employs digital communications, relation between the strain value and the output voltage is fixed, and calibration of output voltage is not necessary. In addition to the miniaturization of the transmitter main body, the use of frequency band of 315MHz (extremely low power radio station) makes the whole system including antenna very small. As for the power source, continuous power supply using an inductive method (option) is available in addition to the use of battery. The receiver is small and easy to operate.
