Title:
SENSING DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/188992
Kind Code:
A1
Abstract:
Provided is a sensing device that uses a detection sensor that comprises a temperature adjustment mechanism for adjusting the temperature of a piezoelectric vibrator according to a voltage and causes the desorption of an object to be sensed from the piezoelectric vibrator by increasing/decreasing the temperature, wherein a voltage adjustment unit for adjusting a voltage for adjusting the temperature of the temperature adjustment mechanism is made to be common and not dependent on the temperature adjustment mechanism of the detection sensor. A drive voltage is adjusted such that the amplification factor for the temperature adjustment voltage input into the drive voltage adjustment unit 73 for adjusting the temperature of the temperature adjustment mechanism is adjusted according to the type of a detection sensor 2 connected to a device body part 3. As a result, when a CQCM sensor 2A that heats a crystal oscillator 4 using a heater circuit 41 and a TQCM sensor 2B that adjusts the temperature of a crystal oscillator 4 using a Peltier element 43 are both used, the adjustment range of the drive power supplied to the heater circuit 41 and Peltier element 43 can be changed.
