How to choose the right weight transmitter

Weight transmitters, like sensors, play a pivotal role in the fields of instruments, meters and industrial automation. Unlike sensors, weight transmitters generally have a certain amplifying effect in addition to converting non-electricity into measurable electricity.

Weight transmitters are also called pressure transmitters or differential transmitters, which are mainly composed of pressure measuring original sensors, module circuits, display headers, watch cases and process connections. It can convert the received pressure signals of gas, liquid, etc. into standard current and voltage signals, and perform measurement, indication and process adjustment for secondary instruments such as recorders.

The principle of the weight transmitter: the process pressure and the reference pressure respectively act on the two ends of the integrated silicon pressure sensitive element, and the differential pressure causes the silicon wafer to deform, so that the fully dynamic Wheatstone bridge made of semiconductor technology on the silicon wafer Driven by an external power supply, it outputs an mv-level voltage signal proportional to the pressure. Due to the excellent strength of silicon material, the linearity and variation index of the output signal are very high.
