The MEMS chip of intrinsic safety temperature sensor and intrinsic safety vibration sensor for mining uses embedded technology, temperature sensing technology and vibration sensing technology to develop and produce sensors with gao performance, low power consumption and gan disturbance resistance. The products are widely used in the coal mining industry of motor, reducer fan, elevator, air compressor, belt conveyor, water pump and other rotating equipment temperature and vibration measurement.
The whole shell is made of stainless steel or aluminum alloy, and can be installed with thread if there are conditions on the site. The standard thread on the metal shell can be quickly connected with the installation part. Magnetic installation method can also be selected, which eliminates drilling problems on site and makes installation geng more convenient.
Spectral products can provide time domain eigenvalues of velocity and acceleration (effective value, peak value, kurtosis coefficient), time domain eigenvalues of displacement (peak-peak value), spectrum analysis data and fault diagnosis results at the same time.
A variety of signal output options: RS485 type, spectrum type, analog type, LoRa type.
Can choose to upgrade the high temperature resistant model according to the field monitoring needs, the temperature range of the transmitter contact can reach -40-150℃.
The wired data collector is responsible for the signal acquisition, signal processin1756-L72S g, signal analysis and data transmission of the fixed equipment in the coal mine, and completes the real-time analysis of the signal. The obtained vibration amplitude, waveform, spectrum, envelope waveform, envelope spectrum and other parameters that can reflect the vibration characteristics and status of the equipment and components are uploaded to the server of the monitoring center.
The safety vibration sensor for mining is a three-axis sensor: in order to understand the vibration of the motor in the quan plane, the XYZ three-axis sensor is used to measure the front and back, left and right and up and down directions of the motor vibration at the same time. This can provide GENGZHUN accurate and QUAN surface vibration data to help identify the source and type of vibration, thereby pre-ce potential motor failure.
With frequency domain analysis function: Through the vibration signal frequency domain analysis, such as fast Fourier transform (FFT), the vibration signal can be converted into a spectrum diagram, showing the vibration components of different frequencies. This helps determine if there are specific frequency components associated with motor failure, such as resonance or early wear signals, so that measures can be taken in advance for maintenance and repair.
