EJA transmitter is a differential pressure transmitter, The basic principle of the EJA transmitter product in operation is mainly to convert the differential pressure and pressure signals into frequency based models by the H-shaped vibration beam on the monocrystalline silicon resonant sensor, and then transmit them to the pulse counter. The difference in frequency is then transmitted to the CPU processor for data analysis and processing. After passing through the D/A converter, the signal can be converted into the corresponding 4-20mADC output signal, and the EJA transmitter can superimpose a BRAIN/HART digital signal on the analog signal for communication. For the characteristics of the membrane box component, it is often possible to correct the ambient temperature on the memory sensor and the input and output models. After calculation by the central processor of the EJA transmitter, the transmitter can obtain better temperature characteristics. This point and The input/output of static pressure matches, and through I/O The EJA transmitter can also communicate data with external terminal devices or with communication enabled I/O cards in 275 and DCS. The frequency model of the EJA transmitter will not affect its 4-20mA signal during communication.
　　
It is not difficult to see from the above principle of EJA transmitter that EJA transmitter actually has many advantages among peer products
　　
The major advantage of the EJA transmitter lies in its ability to achieve high performance with minimal environmental impact such as temperature and static pressure, in addition to ensuring high precision. In addition, after adopting microcomputer technology, it has a highly intelligent operation and control process, and some complete automatic diagnosis and communication functions are superior to similar products. The stability of the product has also been greatly developed by the developer during production, and maintenance efficiency has been improved after improving stability. Secondly, the EJA transmitter is relatively good in weight and lightweight, and is almost unrestricted in installation and use environments. In addition, the service life of the EJA transmitter is also one of the very good advantages, and its reliability ranks first among similar products.
