Weight transmitters, like sensors, play a pivotal role in instrumentation, instrumentation, and industrial automation. Unlike sensors, weight transmitters generally have a certain amplification effect in addition to converting non-electricity into measurable power.

Weight transmitters are also called pressure transmitters or differential transmitters. They mainly consist of pressure measuring original sensors, module circuits, display heads, case and process connectors. It can convert the received gas, liquid and other pressure signals into standard current and voltage signals, and measure, indicate and process the 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 component, and the differential pressure deforms the silicon wafer to make the full dynamic Wheatstone bridge made of semiconductor technology on the silicon wafer. An mv-level voltage signal proportional to the pressure is outputted by an external power source. Due to the excellent strength of the silicon material, the linearity and variation index of the output signal are high.
