In previous articles, we have introduced the basic principles of temperature sensors. For many metering and industrial processes, it is necessary to directly measure the temperature of the fluid, or u...
I use INA128 to measure a signal. The frequency of the signal varies from 0 to 500Hz. INA128 usually needs to be connected to a resistor, which is the resistor that determines the amplification factor...
There is a project at hand that requires pressure, flow, density transmitters and electronically controlled valves.
The maximum working pressure is 10Mpa, and the medium is cement slurry, which is sli...
I currently have a drawing in my hand, which is drawn with 4 layers. The inner electrical layers are placed on the two middle layers. The first question. For example: there are 5 connected GNDs on the...
