Electronic Differential Pressure Transmitter

Electronic Differential Pressure Transmitter
The Electronic differential pressure transmitter is mainly composed of a load cell sensor, a measuring circuit and a process connection.
It can convert the physical pressure parameters such as gas and liquid felt by the load cell sensor into standard electrical signals, and supply the secondary instrument such as indicating alarm device, recorder, regulator, etc.
