Pressure transmitter has been the development capacitance transmitter proliferation of different types of silicon piezoresistive transmitters, differential inductors and ceramic capacitive transmitter such as the transmitter. In the 1990s, the rapid rise of fieldbus pressure transmitter manufacturers, industrial process control system gradually to fieldbus control system with two-way communications and intelligent instrument control direction. Resulting in a new generation of intelligent pressure transmitter. Their main features are as follows. 1, since the compensation function such as nonlinear, temperature error, response time, noise and cross induction and the like. 2. The self-test at power-on self-diagnostic function, implemented in the work of running checks. 3, has a function of two-way communication system, a closed loop between the microprocessor and the basic work of the sensor. 4, information storage and memory function. 5, the digital output. Based on the above features, precision intelligent pressure transmitter, stability, repeatability and reliability have been improved and improved. Its ability to achieve the two-way communication and remote control of computer software and other state-set range. Model differential pressure transmitter type 1, smart differential pressure transmitter 2, 3 high static pressure transmitter, differential pressure transmitter at the top of the tank, differential pressure transmitter design a level alarm It means a double insurance. Since the measured values ??in the application directly to the tonnage of 3051 pressure transmitter, so what kind of oil storage tanks regardless of the value of the second table shows the number of tonnes of oil inside the tank, avoiding the need for conversion of density determination trouble. _ Honeywell smart pressure transmitter (Online) _ pressure transmitter is provided by Jinan-Technology Limited.
