In order to solve the complex problem of indirect measurement of physical quantity by vibrating wire sensor

it combines the microprocessor with the vibrating wire sensor signal circuit to form an intelligent vibrating wire module with the functions of communication

storing information

measuring temperature and sensor signal transmission

it is embedded in two signal lines of the traditional vibrating wire sensor. which is connected with the instrument and switches the communication line and signal line acted by the hidden ground wire by the electrical signal; make it two-wire intelligent vibrating wire sensor which can directly measure and display pressure

synchronous temperature and other physical quantities and read numbers. It does not carry the calibration data document

does not need to manually copy the number and measurement frequency on the cable head

and does not need to operate to calculate the calibration coefficient and the measured physical quantity. Hundreds of intelligent steel bar gauges

strain gauges and pressure box experiments show that the physical measurement is intuitive

simple

and easy to apply high-precision mathematical models

the accuracy and efficiency of vibrating wire sensor in geotechnical engineering monitoring are generally improved

Two wire system is easy to switch automatically.
