Stainless Steel Explosion-Proof Shell PDS Series Intelligent Pressure Transmitter
PDS intelligent pressure/differential pressure transmitter is a high-precision intelligent pressure/differential pressure transmitter developed by Chongqing Chuanyi Automation Co., Ltd., which integrates advanced design concepts and technologies from around the world. This product adopts the world's advanced monocrystalline silicon composite sensor, highly reliable electronic modular design, precise temperature and linear correction system, and intelligent manufacturing technology, ensuring the high precision, high stability, and consistency of the product.
The product has complete intelligent diagnosis, simulation, monitoring, device status, and various communication functions. It has liquid material specifications, high electromagnetic compatibility indicators, and strong lightning protection characteristics. It has been widely used in industries such as power, metallurgy, chemical, coal chemical, petroleum, petrochemical, environmental protection, building materials, light industry, and nuclear industry.
The basic accuracy of PDS smart transmitter is 0.04% FS (up to 0.025% FS), and it can maintain 99.9% accuracy after continuous use for 10 years, saving considerable maintenance costs. The PDS smart transmitter features a sturdy metal casing and fully sealed measuring components, making it easy to handle extreme chemical and mechanical loads. At the same time, it has strong anti electromagnetic interference capability and lightning protection function, ensuring the high stability and reliability of PDS transmitter. Intelligent diagnosis and simulation.
PDS intelligent transmitter has integrated diagnostic function, which can monitor the operation process and its own status in real time. After exceeding the specified number of events, the transmitter enters a fault alarm state and outputs an alarm current (3.6 or 22.8mA) to provide control signals for system interlocking or SIS safety systems. If a malfunction occurs, the LCD display will automatically display "Err" and automatically analyze and display the faulty component, making instrument maintenance, repair, and replacement easier and more convenient.
The transmitter simulation function can simulate the process state to obtain measurement data, and can also be used to check the connection and output status of the transmitter circuit. The simulation output parameters include pressure, sensor temperature, and electronic component temperature. The simulation output modes include fixed value simulation or linear function simulation. During the simulation process, the output of the transmitter will not change with changes in on-site pressure. After button operation or transmitter shutdown and restart, it will return to its normal measurement state.
