Pump Station Operational Challenges

As the core hub of urban water supply, drainage, and industrial fluid transportation, the stable operation of pump stations directly affects public livelihoods and production efficiency. Imagine a pump station where pumps roar continuously, and every start and stop is accompanied by significant pressure fluctuations. If not handled properly, these fluctuations can cause pipeline ruptures or equipment failures. Even more challenging is that pump station environments are often filled with vibration, water hammer impacts, and moisture—hidden enemies that constantly erode the reliability of monitoring equipment.

The water hammer effect is one of the most common “killers” in pump stations. When a pump suddenly starts or stops, the inertia of the liquid flow generates instantaneous high-pressure shocks that far exceed normal operating pressure. This not only tests the mechanical strength of equipment but may also cause damage or inaccurate readings in traditional pressure instruments. According to industry data, such sudden impacts are among the main causes of unplanned pump station downtime, resulting in hours or even days of production interruption each year.

In addition, continuous mechanical vibration is another major challenge. Vibrations generated during pump operation are transmitted to pressure transmitters, potentially causing internal components to loosen or signals to drift. Over time, measurement accuracy declines, making it difficult for maintenance personnel to trust the data, leading to delayed decision-making. Moist environments further increase the risk of electrical failures, as moisture intrusion into connectors may cause short circuits or corrosion, amplifying safety hazards.

In the face of these challenges, selecting a pressure transmitter capable of withstanding harsh conditions is especially important. Nexisense, a well-known brand in the sensor field, designed the FST800-2100 diffused silicon pressure transmitter specifically to address pump station pain points. It is not merely a measurement tool, but a true “guardian” of pump station stability.

Core Advantages of Diffused Silicon Technology

The working principle of a diffused silicon pressure transmitter is based on the piezoresistive effect on a silicon chip. When pressure is applied, the resistance of the silicon crystal changes, generating an electrical signal. Compared with traditional ceramic or metal strain gauge sensors, this technology offers higher sensitivity and stability. Nexisense’s FST800-2100 model is further optimized on this basis, using advanced diffused silicon sensing elements to ensure accurate data in complex environments.

First, it demonstrates outstanding resistance to water hammer impact. Traditional transmitters often fail at pressure peaks, while the FST800-2100 is designed to withstand overload pressures up to 150% of the rated range. This is achieved through its special diaphragm structure and material processes, which effectively absorb impact energy and prevent damage to core components. In real pump station applications, this means that even with frequent pump start-stop cycles, long-term stability can be maintained and maintenance frequency reduced.

Second, anti-vibration performance is another major highlight of this transmitter. With built-in damping components and a robust housing, it can withstand vibration accelerations of up to 10g without affecting output signal accuracy. Maintenance personnel report that after installation, reading fluctuation rates were reduced by more than 30%, providing a reliable basis for pump automatic control and safety interlocks. In highly vibrating pump rooms, this transmitter acts like a calm observer, continuously delivering clear data to help managers adjust operating parameters in a timely manner.

Finally, the IP65 protection rating ensures reliability in humid environments. This standard means the device is completely dust-tight and protected against water jets from any direction. Nexisense uses sealed designs at electrical interfaces to prevent moisture intrusion and ensure uninterrupted signal transmission. Whether from accidental splashing in the pump station or high ambient humidity, performance remains unaffected, greatly extending the service life of the device.

Practical Application Scenarios in Pump Stations

Integrating the FST800-2100 diffused silicon pressure transmitter into pump station systems can significantly enhance overall efficiency. Take a typical municipal drainage pump station as an example: transmitters installed on inlet pipelines monitor pressure changes in real time. When water hammer characteristics are detected, the control system can be triggered to adjust valve openings, preventing the propagation of shock waves. At the same time, it supports standard 4–20 mA output signals, making it easy to integrate with PLC or SCADA systems for remote monitoring.

In industrial pump stations, such as those in chemical or petroleum transportation, the advantages of this transmitter are even more evident. Facing corrosive media and high-temperature environments (operating temperature range from -40°C to 85°C), it can still maintain an accuracy of 0.5% FS, ensuring process safety. Nexisense user cases show that a large wastewater treatment plant reduced unplanned downtime by 40% after adopting the FST800-2100, with corresponding reductions in maintenance costs.

Installation is also relatively simple. The transmitter adopts standard G1/4 or M20x1.5 interfaces and supports wall-mounted or pipeline installation. After initial calibration, frequent adjustments are rarely needed, which is a significant convenience for busy pump station teams. Combined with Modbus RTU communication protocol, it can also network with other sensors to form an intelligent monitoring system, further optimizing energy consumption.

Of course, no device is universally applicable. It is recommended that during model selection, you consult the Nexisense professional team based on the specific pressure range (0–100 bar optional) and media type of your pump station to ensure optimal matching.
