Product Features
? ? ? ? This is an integrated measurement module for measuring vibrating wire sensors. It can complete vibrating wire excitation signal transmission, frequency acquisition, signal filtering, temperature sensor measurement, etc., and convert it into digital signal output. It has small size, low power consumption, and fast response. It can be widely used in geotechnical automatic monitoring, equipment research and development, civil engineering laboratories, digital sensors, real-time monitoring of construction machinery and other fields.

Register address:
Address | Operated | Meaning |
0x0000 | R | Read the sensor frequency value,
divide the reading value by 10, which corresponds to 0-6500Hz |
0x0001 | R | Read 1 channel temperature sensor, the temperature range is
-50°C~100°C, the reading value is subtracted by 500 and divided by 10 |
0x0002 | R | Read the 2-channel temperature sensor, the temperature range is
-50℃~100℃, the
reading value is subtracted by 500 and divided by 10 |
0x0003 | R | Read the 3-channel temperature sensor, the temperature range is
-50°C~100°C, the reading value is subtracted by 500 and divided by 10 |
Example: Read the sensor frequency
and the temperature of channel 1

Among them, 1D 83: the vibrating
wire reading value of 7555/10 corresponds to the vibrating wire frequency of
755.5HZ
02 D5: Temperature reading (725-500)/10
corresponds to a temperature of 22.5°C
