Pressure transmitters are divided into two types: analog signal output and digital signal output according to different signal output forms. With the rapid development and popularization of computer technology and network technology, digital pressure transmitters have gradually been recognized, and the market demand is increasing, especially the rapid development of microelectronics technology makes digital integrated circuits increasingly rich in types, and the performance-price ratio is getting higher and higher. The analog pressure transmitter can only be transmitted remotely in the form of 4~20 mA current or frequency, and the transmission distance is short under the premise of ensuring accuracy, and it can only be connected in a star shape on the network, and its address is determined by a network line. In contrast, digital pressure transmitters can have a variety of communication forms, such as: RS485, MODEM, optical cable, etc. Taking RS485 as an example, it can transmit at least 1000 meters at a communication rate of 9600 bits per second, and can be connected in either star mode or bus mode on the network. The advantage of RS485 is that it is connected by bus, because the entire network only needs two wires, and each digital transmitter has its own address, which is no longer determined by the network cable. Digital pressure transmitters have microcontrollers, making the transmitter easy to achieve intelligence, currently mainly manifested in the central monitoring computer on the network can directly through the RS485 network to automatically complete the zero and full adjustment of the remote sensor. Whether it is engaged in production or use, it has become more automated. Digital pressure transmitters have a broad future in the future.
