Title:
WIRELESS MEASUREMENT DEVICE AND WIRELESS TEMPERATURE MEASUREMENT SYSTEM
Document Type and Number:
WIPO Patent Application WO/2011/081102
Kind Code:
A1
Abstract:
Provided is a wireless measurement device that efficiently measures the frequency characteristics of a sensor unit attached to an element being measured. The wireless measurement device is for measuring the frequency characteristics of a sensor unit (10) attached to an element being measured (40), and includes: the sensor unit (10) which has a piezoelectric resonator (11); an antenna (20) for creating a circuit network with the sensor unit (10); and a measurement means (30) which supplies frequency-modulated high-frequency power to the circuit network and measures the frequency characteristics of the power intensity reflected from the circuit network.
