The design principles and product features of the Rosemount 3051C coplanar pressure transmitter.

When it comes to the Rosemount 3051C coplanar pressure transmitter, many users are likely very familiar with it. This is because it is the most widely used transmitter from Rosemount, with global installations reaching over ten million units. It can be said that it is the best-selling transmitter in the world. So why does it have such impressive sales and usage rates? This is mainly due to its design principles and product features. Today, the technical editor from Shaanxi Huibo Electromechanical will decode the design principles and product features of the Rosemount 3051C coplanar pressure transmitter for you.
The Rosemount 3051C coplanar design is primarily used for measuring differential pressure (CD), gauge pressure (CG), and absolute pressure (CA). The Rosemount 3051C coplanar pressure transmitter mainly utilizes the capacitive sensor technology from Rosemount Inc. to measure differential and gauge pressure. The piezoresistive sensor technology is used for the 3051T and 3051C absolute pressure measurement sensors.
The main components of the Rosemount transmitter are the sensor module and the electronic component housing. The sensor module includes an oil-filled sensor system (isolation diaphragm, filling system, and sensor) as well as the sensor's electronic components. The sensor's electronic components are installed within the sensor module and include a temperature sensor (resistive temperature detector), storage module, and capacitive/digital signal converter (C/D converter). The electronic signals from the sensor module are transmitted to the output electronic components housed in the electronic component enclosure. The electronic component enclosure includes the output electronic circuit board (microprocessor, storage module, digital/analog signal converter or D/A converter), local zero and range buttons, and terminal block.
Because the design pressure of the Rosemount 3051C transmitter is suitable for the isolation diaphragm, when the oil deviates from the center diaphragm, it changes the capacitive signal. This capacitive signal is then converted into a digital signal in the C/D converter. Subsequently, the microprocessor retrieves signals from the resistive temperature detector and the C/D converter to calculate the correct transmitter output. This signal is then sent to the D/A converter, which converts the signal back to an analog signal and superimposes the HART signal on the 4-20 mA output.
