Vibrating wire frequency meter
Vibrating frequency instrument uses advanced microcontroller hardware and software technology to trigger the excitation intermittently vibrating wire sensor and measuring its exact science. Vibrating frequency analyzer is equipped with an ordinary oscilloscope, but also for a sensor manufacturer or user Observe the output waveform of the vibrating wire sensor and its amplitude , attenuation and other indications , for the production debugging of the sensor , pros and cons and fault diagnosis .
Derived varieties of vibrating wire frequency vibrating wire frequency meter , the measurement principle and precision of the two are consistent. However, it pays attention to the comprehensive functions , such as the functions of storage , printing , inspection , computer transmission and control ; it pays attention to the advantages of firmness and lightness , simple operation , not easy to damage , and long working time .
The improved vibrating wire frequency meter ( temperature measurement ) can directly measure the temperature , and only needs to install the temperature measuring component on the sensor , and the temperature measurement precision is high.
