The Application of PST Pressure Sensor in Boiler Pressure Control

Boilers are important energy devices in industrial production, and their safe and efficient operation is of great significance. To ensure the stable operation of boilers, the control of pressure is a very crucial step. The PST pressure sensor independently developed by Yuanben Company, with its outstanding performance advantages, provides a stable and reliable technical solution for the boiler pressure control system. -Boiler pressure sensor

The Importance of Boiler Pressure Control

During the operation of a boiler, the internal pressure fluctuates due to various factors such as combustion and water level changes. If the pressure is too high, it may lead to serious safety accidents such as boiler explosions; while if it is too low, it will affect the thermal efficiency of the boiler and fail to meet production demands. Therefore, precise and stable control of boiler pressure is a necessary condition for ensuring the safe and efficient operation of the boiler.

Advantages of PST Pressure Senso

1. High Precision and High Resolutionrs

PST pressure sensors employ high-precision silicon piezoresistive cores, capable of accurately measuring pressure changes within boilers. Their high-resolution feature enables precise detection of even minor pressure fluctuations, providing a solid data foundation for precise boiler pressure control. For instance, during the initial stage of boiler startup, when pressure gradually increases from a lower value, PST pressure sensors can promptly feedback pressure changes, allowing the control system to make precise adjustments.

2. Resistance to Electromagnetic Interference

The operating environment of boilers often features complex electromagnetic interference, such as electromagnetic fields generated by motors and frequency converters. PST pressure sensors are equipped with an anti-electromagnetic interference system, enabling stable operation in such complex environments and ensuring the accuracy of measurement signals. This prevents pressure measurement errors caused by electromagnetic interference, thereby guaranteeing the reliable operation of the boiler pressure control system.

3. Durable Stainless Steel Housing

The internal environment of boilers is typically high-temperature and may contain corrosive media such as water vapor. The housing of PST pressure sensors is made of stainless steel 316L, which is resistant to high temperatures and corrosion, allowing for long-term stable operation in the boiler environment. The small temperature drift advantage also ensures the stability of pressure measurement under different temperature conditions, reducing measurement errors caused by temperature changes.

4. Convenient Installation and Connection

The connection ports of the PST pressure sensor housing are M10×1 and M14×1.5, a standardized interface design that makes installation and removal of the sensor on the boiler very convenient. When maintenance or replacement of the sensor is required in the boiler pressure control system, operations can be completed quickly, reducing downtime. Additionally, its multi-wire or multi-core plug electrical connection method is compatible with various control systems, facilitating integration with the boiler's automated control system.

The Application of Pressure Sensors in Boiler Pressure Control

1. Real-time Pressure Monitoring

Pressure sensors are installed at key locations in the boiler, such as the steam drum and super heater, to monitor the pressure inside the boiler in real time. By transmitting the measured pressure signals to the control system, operators can keep track of the boiler's operating status at any time. For instance, during normal operation, the sensors continuously provide pressure data. When the pressure approaches the upper or lower limit set, the control system will adjust parameters such as combustion intensity and water supply based on these data to keep the boiler pressure within a safe range.

2. Pressure Control and Alarm

In combination with the boiler's automated control system, pressure sensors can achieve automatic pressure control. When the pressure exceeds the set safety threshold, the sensor will trigger an alarm signal, and the control system will take corresponding measures, such as stopping combustion and opening the safety valve, to prevent the boiler pressure from getting too high. This automated pressure control and alarm mechanism significantly enhances the safety of boiler operation and reduces the errors and risks associated with manual intervention.

3. Improving Boiler Operating Efficiency

The high-precision measurement capability of pressure sensors helps achieve precise control of boiler pressure. By precisely controlling the pressure, the combustion process of the boiler can be optimized, improving the utilization rate of fuel and thereby enhancing the boiler's thermal efficiency. For example, in steam boilers, maintaining an appropriate pressure ensures the quality and flow of steam, meeting the demands of production processes while reducing energy waste.

The PST pressure sensors produced by Yuanben Company have played a significant role in boiler pressure control due to their high precision, strong resistance to electromagnetic interference, and durability. They can not only monitor the boiler pressure in real time and accurately but also work in conjunction with the automatic control system to achieve automatic control and alarm, thereby enhancing the safety and efficiency of boiler operation.
