Overview
3000 series pressure transmitter is the use of capacitive pressure sensor as sensitive components, integrated circuits with high stability and precision surface mount technology. Analog model easy to adjust; Smart model has so many special functions such as communications system, inquire, testing, module-combined etc., and it used ADC with 24-bit resolution, greatly improving the accuracy and digital compensation for the high and low temperature to improve the ability to adapt the transmitter to the environment, with 275 and 375 as well as internal HART Communicator is compatible, flexible to module combined in the workshop.

Configuration Dimensions
Transportation and storage
1. By air/sea/truck/railway; by express;
2. The products and accessories shall be stored indoors under the original packaging conditions, with the ambient temperature within -10~+55 ºC and the relative humidity not more than 85%.
Transmitter can measure flow, level of liquid, also it applies to the measurement of pressure and differential pressure accurately.It is very important to assemble the Pressure transducer and the guide tube correctly, or it is easy to affect the accuracy. Due to process requirements and consider saving materials , installation of the transmitter in the working conditions are often more serious, the transmitter should be installed in place where small temperature gradient and low temperature variation, no shock and no vibration.

Application in coal washing industry
The online density meter used for coal washing of heavy media includes a radioactive isotope density meter. Since there are radioactive substances in it, it can cause radioactive pollution to the surrounding environment and cause radioactive radiation damage to people, and is inconvenient to use and manage, and strictly controlled by the country, and its use and purchase need to go through strict approval procedures. If it is damaged and cannot be used, it costs money to be stored in a stage-designated unit and location. If it is lost, relevant personnel need to bear criminal responsibility. This kind of instrument features large time constant, insensitive response and low measurement accuracy, and is difficult to calibrate during use, and difficult to calibrate accurately. It has strict requirements for installation position, and is very troublesome to use and maintain. The scaling on the inner wall of the sampling tube affects the measurement accuracy.
To adapt to market needs and overcome the shortcomings and problems with the above instruments, Zhongshan Sani Measuring Instruments Co., Ltd. develops the double-flange density meter according to differential pressure principle. It adopts a multi-parameter density sensor, and support automatic temperature compensation, easy installation, and little maintenance.
