Specific embodiment
Shown in Fig. 1：Piezoelectric transducer 1 is connected with cpu circuit 5, and cpu circuit 5 passes through signal transmission circuit 6 and transmitting antenna
7 are connected, and reception antenna 8 is connected by signal receiving circuit 9 with rotating speed display circuit 10；Precompressed bullet in the piezoelectric transducer 1
Spring 11 is connected with mass 2, and piezoelectric element 3 is fixedly linked with pedestal 4, interior one end fixing phase of pedestal 4 and piezoelectric transducer 1
Even, pre-compressed spring 11 is also fixedly linked with the interior other end of piezoelectric transducer 1.
Shown in Fig. 2：Piezoelectric transducer 1 is fixedly linked with rotary body 12, and piezoelectric transducer 1 is connected with cpu circuit 5, CPU electricity
Road 5 is connected by signal transmission circuit 6 with transmitting antenna 7；Rotary body 12 is horizontal positioned.
Operation principle of the present utility model is as follows：When the rotary body 12 of horizontal positioned does not rotate, pre-compressed spring 11
Elastic force makes have a precompressed between mass 2 and piezoelectric element 3, and piezoelectric transducer 1 has a voltage signal output to cpu circuit
5, by the sequential operation in cpu circuit 5, rotating speed display circuit 10 can be made to show that rotating speed is zero.
When the ultrahigh speed of rotary body 12 rotates, the power that piezoelectric element 3 is subject to is the precompression and rotary body of pre-compressed spring 11
Centrifugal force during 12 rotation produced by mass 2 is made a concerted effort.Due to square being directly proportional for centrifugal force and rotating speed, by cpu circuit 5
In sequential operation, cpu circuit 5 makes transmitting antenna 7 send rotating speed electric signal this moment, reception antenna 8 by signal transmission circuit 6
This signal is received, rotating speed display circuit 10 is arrived in output after being processed through signal receiving circuit 9, and rotating speed display circuit 10 shows and now revolve
The rotating speed of swivel 12.
Because rotary body 12 is horizontal positioned, therefore the gravity and the centrifugal force produced by mass 2 of mass 2 are mutual
Vertical, the power that piezoelectric element 3 is subject to is unrelated with the gravity of mass 2.
So, using mass 2, piezoelectric element 3, cpu circuit 5 and rotating speed display circuit 10, realize to rotary body 12
Ultrahigh speed rotating speed on-line real-time measuremen.
