Where does the pressure transmitter come from?

The pressure transmitter is developed from the sensor. all the sensors that can output standard signals, the standard signal refers to the signal in which the form and quantity range of physical quantities are in line with international standards. 

Because the DC signal is not affected by the inductance, capacitance and load in the line, and there is no phase shift problem, the International Electrotechnical Commission (IEC) determines the current signal 4mA~20mA (DC) and the voltage signal 1V~5V (DC) as the unified standard of analog signal in the process control system. 

Sensor-A device or device that can sense regular measurements and transform them into available output signals in accordance with the rules. 

It is generally composed of sensitive elements and transform elements. 

The simple sensor is composed of an element (and a conversion element), which directly outputs electricity when it is measured, such as thermal resistance, thermocouple and so on. 
Sensor skills-discuss the material, design, technology, function and use of the sensor. 

Sensing skill is a marginal skill, which touches on the research and development of its sensors in physics, mathematics, chemistry and materials. in addition to the research and development of its chips, attention should also be paid to the study of the packaging technology and structure of the sensor. this is often one of the key factors that cause the sensor to work unsteadily. 

The effect of the sensor is more and more known by the industry, the scientific and technological community, and the leadership decision plan part. 
This is because sensing skills are one of the three major components of information skills.
