Application of eddy current sensor WT0112-A50-B00-C00 in steam turbine operation

In order to ensure the normal operation of the steam turbine, it is necessary to accurately measure its key parameters such as speed, expansion difference, displacement, etc. As a high-precision and high-reliability sensor, WT0112-A50-B00-C00 eddy current sensor is widely used in the real-time monitoring system of steam turbines, providing a strong guarantee for the stable operation of steam turbines.

Characteristics of WT0112-A50-B00-C00 eddy current sensor

WT0112-A50-B00-C00 eddy current sensor is a sensor designed for steam turbine monitoring. It has the characteristics of good long-term working reliability, high sensitivity, strong anti-interference ability, non-contact measurement, and fast response speed. It has a wide measurement range and can adapt to different working environments and measurement requirements. The sensor system mainly includes probes, extension cables, preamplifiers and accessories. It has a compact structure, is easy to install, and can maintain stable performance in harsh working environments.

1. Probe: The probe is the core component of the sensor, which consists of a coil, a head, a shell, a high-frequency cable and a high-frequency connector. The coil is the sensitive element of the probe, and its physical size and electrical parameters determine the linear range and electrical parameter stability of the sensor system.

2. Extension cable: The extension cable is used to connect the probe and the preamplifier. Cables of different lengths can be selected as needed to meet different installation requirements.

3. Preamplifier: The preamplifier is an electronic signal processor that provides high-frequency AC current to the probe coil and senses the changes in probe parameters caused by the proximity of the metal conductor in front of the probe. After processing by the preamplifier, an output voltage corresponding to the linear change in the gap between the probe end face and the measured metal conductor is generated.

Application of WT0112-A50-B00-C00 in turbine speed measurement

The turbine speed is one of the important indicators for evaluating its performance. The WT0112-A50-B00-C00 eddy current sensor indirectly measures the turbine speed by measuring the rotation speed of the speed measuring disc on the turbine shaft. The speed disc is a disc with small holes installed on the shaft of the turbine. The sensor probe is aligned with the small holes on the speed disc. When the speed disc rotates, the small holes pass through the probe in turn, causing the sensor to output a pulse signal. The frequency of the signal is proportional to the speed of the speed disc. By measuring the frequency of the signal, the speed of the turbine can be calculated.

In practical applications, in order to accurately measure the speed, the following points should be noted:

1. Design of the speed disc: The number and distribution of small holes on the speed disc should be reasonable to ensure the accuracy and stability of the measurement results.

2. Installation of the probe: The probe should be installed in the diameter direction of the speed disc, and the gap between the probe and the convex head of the speed disc should be appropriate to avoid errors or damage to the probe.

3. Signal processing: The pulse signal output by the sensor is converted into a digital signal through measuring equipment such as a digital frequency meter, and processed and analyzed to obtain an accurate speed value.

Application of WT0112-A50-B00-C00 in turbine differential expansion measurement

Turbine differential expansion refers to the relative displacement between the shaft and the bearing seat caused by temperature changes during the start-up and shutdown process of the turbine. The measurement of differential expansion is of great significance to ensure the safe operation of the turbine. The WT0112-A50-B00-C00 eddy current sensor indirectly measures the differential expansion by measuring the relative displacement between the turbine shaft and the bearing seat. The sensor probe is installed on the bearing seat and aligned with the turbine shaft. When the shaft is displaced, the sensor will output a corresponding signal. By measuring the change in the signal, the differential expansion value can be calculated.

In practical applications, in order to accurately measure the differential expansion, the following points should be noted:

1. Sensor selection: Select the appropriate sensor model and measurement range according to the model and measurement requirements of the turbine.

2. Probe installation: The probe should be installed on the bearing seat, and the installation position should be stable and reliable to avoid measurement errors caused by vibration and other reasons.

3. Signal processing: Through the signal conditioning circuit and data processing software, the signal output by the sensor is converted into the expansion difference value, and it is displayed and recorded in real time.

Application of WT0112-A50-B00-C00 in turbine displacement measurement

Turbine displacement refers to the relative position change of the turbine shaft in the bearing. The displacement measurement is of great significance for monitoring the operating status and fault analysis of the turbine. The WT0112-A50-B00-C00 eddy current sensor measures the displacement by measuring the relative displacement between the turbine shaft and the bearing. The sensor probe is installed on the bearing and aligned with the turbine shaft. When the shaft is displaced, the sensor will output the corresponding signal. By measuring the change in the signal, the displacement value can be calculated.

In practical applications, in order to accurately measure the displacement, the following points need to be noted:

1. Sensor selection: According to the model of the turbine and the measurement requirements, select the appropriate sensor model and measurement range.

2. Probe installation: The probe should be installed on the bearing, and the installation position should be stable and reliable to avoid measurement errors caused by vibration and other reasons. At the same time, the gap between the probe and the turbine shaft should be appropriate to ensure the accuracy of the measurement.

3. Signal processing: Through the signal conditioning circuit and data processing software, the signal output by the sensor is converted into a displacement value, and displayed and recorded in real time. At the same time, the displacement data can be trend analyzed and fault diagnosed to detect potential problems in advance and take corresponding measures.

WT0112-A50-B00-C00 eddy current sensor has a wide range of application prospects in the operation of steam turbines. By accurately measuring key parameters such as the speed, expansion difference and displacement of the steam turbine, it can provide a strong guarantee for the stable operation of the equipment. In practical applications, it is necessary to select a suitable sensor model and measurement range according to the model and measurement requirements of the steam turbine, and pay attention to issues such as the installation and signal processing of the probe to ensure the accuracy and stability of the measurement results.
