The rotational speed sensor CS-1-L120 uses the principle of electromagnetic induction to measure speed. A coil is wound around the front end of the sensor. When the gear rotates, the magnetic lines of force passing through the sensor coil change, thereby generating a periodic voltage in the sensor coil. This voltage signal is proportional to the speed of the gear. Through subsequent signal processing, the speed of the steam turbine can be accurately measured.

Technical Specifications

• Measuring range: rotational speed sensor CS-1-L120 can measure the speed range of 100 to 10,000 rpm, which enables it to adapt to the needs of steam turbine speed monitoring under various working conditions.

• Output signal: Under the conditions of a gear module of 4 and a number of teeth of 60, and a distance of 1mm between the sensor and the gear, when the speed is 1,000 rpm, the output signal is greater than 5V peak-to-peak; when the speed is 2,000 rpm, the output signal is greater than 10V peak-to-peak.

• Operating temperature: The sensor has an operating temperature range of -20°C to 120°C, which enables it to work stably in harsh industrial environments.

• Gear material: Suitable for gears made of metal materials with strong magnetic permeability, ensuring the accuracy and stability of the signal.

The rotational speed sensor CS-1-L120 is widely used in turbine speed monitoring. During the operation of the turbine, real-time and accurate monitoring of the speed is essential for controlling the operating status of the turbine, preventing overspeed accidents, and optimizing operating efficiency. By connecting to the control system, the CS-1-L120 can provide reliable data support for the automatic control and protection of the turbine.

Advantages and features

• High anti-interference performance: The special metal shielded soft wire is used to effectively resist external electromagnetic interference and ensure stable signal transmission.

• Strong durability: The housing is made of stainless steel, with good high temperature resistance and corrosion resistance, suitable for long-term use in harsh environments such as smoke, oil vapor, and water vapor.

• Easy installation: The sensor has a flexible installation method and can be easily integrated into the existing turbine monitoring system.

When installing the rotational speed sensor CS-1-L120, it is necessary to ensure that the gap between the sensor and the gear meets the requirements. The generally recommended gap is 0.8 to 1.5 mm. In addition, checking the integrity of the sensor’s wiring, connectors, and shielding layer is also a key step to ensure its normal operation. Regular maintenance and inspection can extend the service life of the sensor and ensure its measurement accuracy.

In summary, the rotational speed sensor CS-1-L120 has become a reliable choice in the field of turbine speed monitoring with its high precision, strong anti-interference ability and wide applicability. It can not only provide strong protection for the safe operation of the turbine, but also help improve the operating efficiency of the entire system through accurate speed data.
