The rotation speed sensor CS-3F-M16-L100 is an expert at processing fast-changing speed signals. In high-speed equipment such as steam turbines, accurate speed measurement is crucial. The CS-3F-M16-L100 sensor was born for this purpose. It can ensure accurate data and avoid data distortion even when the speed signal changes rapidly. Next, let’s talk about how it does it.

The CS-3F-M16-L100 sensor is a magnetoresistive speed sensor. It is designed to capture the rotation information of the gear plate on the turbine shaft and then convert it into an electrical pulse signal. During the operation of the steam turbine, the speed signal changes very quickly, especially when starting, accelerating, decelerating or when the load changes suddenly. At this time, the ability of CS-3F-M16-L100 is revealed.

The reason why the CS-3F-M16-L100 rotation speed sensor can respond quickly is due to its magnetoresistive effect. When the sensor is close to the rotating gear, the tooth surface and gap of the gear alternately pass through the magnetic field of the sensor, which causes periodic changes in the magnetic field. The magnetic resistance element inside the sensor can quickly sense these changes and immediately generate corresponding pulse signals. This design allows the sensor to respond extremely quickly, and even in the face of rapidly changing speeds, it can keep up with the rhythm and ensure the real-time nature of the data.

The pulse signal collected by the sensor will be sent to the signal processor for processing. The technical key here lies in signal shaping and filtering. The signal shaping circuit converts the pulse signal into a uniform rectangular pulse. The advantage of this is that even if the original signal becomes blurred due to noise or interference, after shaping, the signal edge becomes clean and neat, which is convenient for subsequent counting and analysis.

The filtering link is responsible for removing clutter in the signal and retaining pure pulse signals. In the operating environment of the steam turbine, electromagnetic interference is common. If there is no effective filtering measure, the data is easily distorted. The built-in filtering circuit of the CS-3F-M16-L100 sensor can effectively suppress noise and ensure the clarity and accuracy of the pulse signal.

On the steam turbine, rotation speed sensors like this one that monitor overspeed protection also have a set of “three-choose-two” logic, which is to avoid data errors caused by single sensor failure. In actual applications, three such sensors are usually installed on the steam turbine, and each sensor measures the speed independently. When the data enters the control system, the system will select the data of two of the sensors for comparison, and only when the two data are consistent will they be adopted. In this way, even if there is a problem with one sensor, it will not affect the final measurement result, ensuring the reliability and accuracy of the data.
