I would like to ask, under what circumstances do you need to use a pressure sensor? And under what circumstances do you need a pressure transmitter?
The pressure transmitter is composed of a pressure sensor and a ASIC amplifier circuit, an amplifying circuit is connected to the pressure sensor, the pressure sensor will feel the pressure to transfer the information out of the current or voltage signal forms, to understand the pressure by observing the size of these signals. The use of industrial general are pressure transmitter, is through the current or voltage signal transmitter output to control, only in special industries and special requirements, can only pressure sensor.
The pressure sensor does not mean stress or pressure.Usually called is not very standardized. Pressure transmitter is a kind of instrument that has the function of changing the size of pressure signal to remote transmissionThere is a pressure sensor in the pressure transmitter, such as the Ross Monte 3051 pressure transmitter or the differential pressure transmitter. There is a diffused silicon pressure sensor. The pressure sensor output signal through a tuning and according to the need of conversion, such as converted into standard 4-20mA current signal or 0-5V voltage signal or PF bus or HART have a follow-up to the remote communication equipment for subsequent "transmission" concept.At present, the industrial field for measuring pipeline and container process and so on non special type of solid, such as gas, vapour, liquid, semi liquid media usually use pressure transmitterUsed to measure a single solid or weighing strain, etc. mechanical pressure sensors follow the subsequent processing unit or display unit to achieve measurements.
The sensor can only show pressure or no pressure. The transmitter can display real-time pressure
