Rich Interface Configuration: It is equipped with rich interface options such as RS485 interface and Ethernet interface. The RS485 interface is suitable for long-distance and multi-node data transmission. In distributed pressure monitoring systems of some large factories, multiple FOXBORO RH924WA can be connected through RS485 interfaces to form a large pressure monitoring network. The Ethernet interface provides a high-speed data transmission channel, facilitating data interaction with upper computers or remote monitoring systems to achieve remote real-time monitoring. Through the Ethernet interface, enterprise managers can view real-time pressure data of various key positions in the production site in the office and keep abreast of production conditions.
II. Application Fields
(1) Oil and Gas Industry
Oil Well Pressure Monitoring: In the process of oil well exploitation, accurately grasping the oil well pressure is crucial for ensuring exploitation efficiency and safe production. FOXBORO RH924WA can real-time monitor the pressure changes inside the oil well, helping workers adjust exploitation strategies in a timely manner. When the oil well pressure drops abnormally, it may indicate changes in the reservoir permeability or equipment failures. Through the accurate monitoring of this device, operators can quickly take corresponding measures, such as adjusting the working parameters of the pumping unit or arranging equipment maintenance, to ensure the stable production of the oil well.
Pipeline Pressure Maintenance: In long-distance oil and gas transmission pipelines, stable pressure is a key factor to ensure transmission safety. FOXBORO RH924WA is distributed at various key nodes of the pipeline to continuously monitor pipeline pressure. Once the pressure exceeds the normal range, it will immediately transmit the abnormal signal to the control system, which will activate corresponding protection mechanisms, such as adjusting valve openings and starting backup pumps, to prevent serious accidents such as pipeline rupture and leakage caused by excessive or insufficient pressure, ensuring the safety and stability of energy transmission.
Storage Tank Pressure Management: During the storage of oil and gas in storage tanks, the internal pressure needs to be strictly controlled. FOXBORO RH924WA real-time monitors the storage tank pressure. When the pressure is close to the safety upper limit, the system can automatically activate the pressure relief device to prevent the storage tank from being in danger due to overpressure; when the pressure is too low, it can also take timely measures such as air supplementation to maintain the normal operation state of the storage tank and ensure the safety and stability of the storage process.
(2) Chemical Industry
Reactor Pressure Regulation: Reactors in chemical production are core equipment, and their internal pressure directly affects the progress of chemical reactions and product quality. FOXBORO RH924WA real-time monitors the reactor pressure, and cooperates with the control system to automatically adjust parameters such as feed amount and temperature according to the reaction process, ensuring that the reactor pressure is always in the optimal reaction range. In the ammonia synthesis production process, through precise control of the reactor pressure, the ammonia synthesis efficiency can be improved, energy consumption can be reduced, and the safety of the production process can be ensured, avoiding serious accidents such as explosions caused by pressure out of control.
Pipeline Pressure Monitoring: Chemical pipelines transport various corrosive, flammable, and explosive media, and stable pressure is crucial for the safe operation of pipelines. FOXBORO RH924WA monitors the pipeline pressure throughout the process, timely detects pressure abnormalities caused by pipeline blockages, corrosion perforations, etc., and provides accurate basis for pipeline maintenance. In pipelines transporting highly corrosive media such as sulfuric acid, through monitoring pressure changes, the corrosion of the pipeline inner wall can be timely detected, and pipeline repair or replacement can be arranged in advance to prevent media leakage from harming the environment and personnel.
Product Pressure Detection: In the production and packaging of chemical products, accurate pressure detection of products is required. For example, in the production of aerosol products, FOXBORO RH924WA is used to detect the pressure inside aerosol cans to ensure the quality stability and use safety of products within the shelf life. Only products with pressure meeting the standards can be sold on the market, which not only protects the rights and interests of consumers but also maintains the corporate brand image.
(3) Power Industry
Boiler Pressure Monitoring: Boilers are important equipment in power production, and the stability of their operating pressure is directly related to power generation efficiency and equipment safety. FOXBORO RH924WA real-time monitors the pressure of boiler drums, superheaters, reheaters, etc. When abnormal pressure fluctuations occur, it timely sends signals to the control system to adjust parameters such as fuel supply and air volume of the burner, maintaining stable boiler pressure. In coal-fired boilers, through precise control of pressure, coal combustion efficiency can be improved, pollutant emissions can be reduced, and accidents such as tube bursts caused by excessive pressure can be avoided, ensuring the long-term stable operation of the boiler.
Turbine Pressure Control: The normal operation of a turbine depends on the stability of steam pressure. FOXBORO RH924WA monitors the inlet and exhaust pressure of the turbine, provides accurate pressure data for the turbine's speed control system, and realizes precise control of the turbine's speed and output power. When the power grid load changes, by adjusting the turbine inlet pressure, it can quickly respond to load demands, ensuring the stability and reliability of power supply.
Condenser Pressure Management: The pressure of the condenser has an important impact on the operating efficiency of the turbine. FOXBORO RH924WA monitors the condenser pressure, and maintains the condenser pressure within a reasonable range by adjusting the circulating water volume, vacuum pump working status, etc., improving the thermal efficiency of the turbine and reducing power generation costs. At the same time, pressure monitoring also helps to timely detect faults such as condenser leakage, ensuring the normal operation of the equipment.
