厦门Vibration string crack meter acquisition card

I. The vibration string crack meter acquisition module overview:

The acquisition card module of Milan RS485 vibrating wire sensor can convert the vibration frequency signal of vibrating wire sensor into displacement through RS485 and output by MODBUS-RTU protocol, and realize the function of calibration of different vibrating wire sensors by users through serial port instructions. After the user completes the calibration operation of temperature coefficient, linear coefficient, starting point and temperature, the linear output is realized according to the calibration coefficient, and the part outside the calibration is regarded as the dead zone.

II. Vibrating string crack meter acquisition module description:

The vibrating string acquisition module is specially designed for the environment with serious interference. In the daily operating environment, analog signal transmission is prone to interference. Transmission wire quality, peripheral equipment configuration, and wire installation environment can greatly affect analog signal transmission.

The module is used with the output of the RS485 digital signal of Milan vibrating string displacement sensor. The sensor triggers the natural vibration through the incoming excitation signal of the module, and then the module collects the natural vibration frequency of the sensor, obtains the displacement data after decoding, and then outputs the real-time signal to the PC through the RS485 module.

The module has a dedicated power supply voltage filtration and voltage regulation system. Provide a most complete power supply scheme for displacement measurement. The unstable reading caused by the unstable voltage interference caused by the common power supply on the machine is solved.

III. Vibration string crack meter acquisition module features:

● Terminal, pluggable connector is more convenient to use.

● The vibrating string acquisition card is used with the vibrating string sensor, and the vibrating string sensor of different ranges can be replaced at any time for calibration.

IV. Vibrating string crack meter acquisition module precautions:

★ Configuration description: The module must be consistent with the configuration of the vibrating string sensor (baud rate: 9600, data bit 8, stop bit 1, no check, sensor address: 01Hs).
