Intelligent pressure transmitter is a kind of instrument that converts the pressure variable into a standardized output signal that can be transmitted, which is mainly composed of two parts: intelligent sensor and intelligent electronic board. The RH101AA intelligent sensor includes capacitive sensor, measuring diaphragm detection circuit, temperature sensor and temperature compensation circuit, etc. The intelligent electronic board part includes a microcomputer controller and peripheral circuits to complete the conversion of pressure signals to 4 ~ 20mA dc.

The intelligent pressure transmitter has the characteristics of accurate measurement, good stability, fast response speed, high reliability, simple and convenient maintenance, and has the digital communication function, which can communicate with the HART hand operator to set, adjust the pressure range, monitor or form a field monitoring system with the upper unit. In addition, intelligent pressure transmitters are also widely used in industrial pipelines in the weakly corrosive liquid, gas, steam measurement and control system, the measurement range can range from 0 ~ 10KPa to 0 ~ 40MPa.

There are also many types of intelligent pressure transmitters, such as SC308 intelligent pressure transmitter, 3051GP intelligent pressure transmitter, RH101AA intelligent pressure transmitter, 3051TF intelligent pressure transmitter and so on. Different types of smart pressure transmitters may differ in sensor selection, measurement range, accuracy, etc., so it is necessary to choose according to specific application scenarios and needs.

In short, RH101AA intelligent pressure transmitter is an important industrial automation instrument, and its accurate, stable and reliable measurement and digital communication functions provide important support for industrial production and equipment maintenance.
