Common measures for sensor anti-interference
The common measures for sensor anti-interference are as follows: 1. Anti-interference design of power supply system The most serious hazard to the normal operation of sensors and instruments is the peak pulse interference of the power grid, and the electrical equipment that produces peak interference is: welding machines, large motors, controllable machines, relay contactors, inflatable lights with ballasts...

Read and learn2013-05-02There are two main reasons for the unsatisfactory performance of the electrical market
On the one hand, penny stock competition has led to a decline in profits in the electrical industry. The prices of electrical products are actually relatively transparent, just like similar products are particularly cheap, which is nothing more than cutting corners or shoddy charging. The electrical market has endless troubles after low-price bidding, which will inevitably make enterprises unprofitable or squeeze profit margins, so the development of enterprises...

Since 2005, with the support of the National Development and Reform Commission, the China Earthquake Administration has begun to organize the development of seismic acceleration sensors based on next-generation Internet network technology. If a large number of accelerometers are deployed in the area where a large earthquake occurs, we can transfer the extreme seismic area and the earthquake in the area where the earthquake is strongly affected in near real time...
