PDS813 paper type pressure transmitterIt is a pressure detection equipment designed specifically for the harsh working conditions of the paper industry. With customized features such as anti pollution, corrosion resistance, strong stability, and high adaptability, it accurately monitors the pressure parameters of each link in paper production, providing reliable data for process optimization and equipment protection. It is widely used in key processes of paper production such as pulp making, papermaking, and coating. ​

Anti pollution and corrosion-resistant design suitable for harsh working conditions in papermaking. In papermaking production, pulp, black liquor and other media contain a large amount of fibers, impurities and have strong corrosiveness. PDS813 adopts a special material sensor and anti blocking structure design: the diaphragm in contact with the medium is made of Hastelloy or tantalum material, which has strong acid and alkali corrosion resistance; Adopting a structure with a flat membrane or isolation membrane to avoid fiber and impurity accumulation blocking the pressure interface, effectively solving the problem of traditional transmitters being prone to blockage and damage. In the pressure monitoring of the cooking pot in the pulp workshop, it can withstand the corrosion and erosion of high-temperature black liquor for a long time; In the pressure detection of the web section of the paper machine, it can resist the entanglement and pollution of pulp fibers, ensuring stable operation. ​

High precision and stability guarantee process control. The transmitter adopts high-precision piezoresistive sensors and digital signal processing technology, with a measurement accuracy of ± 0.075% FS and a range covering 0-1MPa to 0-40MPa, meeting the different pressure monitoring needs of the paper industry; Has excellent long-term stability, with an annual drift of less than 0.1% FS, reducing the workload of frequent calibration. In the coating process, precise monitoring of the coating roller pressure can ensure uniform coating of the coating and avoid defects such as uneven coating and missed coating on the paper; In the steam pressure control of the dryer, stable pressure data can assist in adjusting the steam supply, ensuring consistent paper drying effect and improving product qualification rate. ​

Intelligence and convenience enhance operational efficiency. The PDS813 paper type pressure transmitter supports standard signal outputs such as HART and 4-20mA, and can be directly integrated with the DCS control system of the paper production line to achieve real-time transmission and centralized monitoring of pressure data; Equipped with a local display module and buttons, it is possible to view pressure values and modify range parameters on site without the need for additional calibration equipment. Some models have self diagnostic functions, which automatically send alarm signals to the control system when sensor failures, signal abnormalities, and other issues occur, making it easier for maintenance personnel to troubleshoot and handle them in a timely manner. Its customized design and reliable performance have become the preferred equipment for pressure monitoring in the paper industry. ​
