In the operation monitoring and control system of steam turbines, LVDT displacement sensors are widely used to measure the linear displacement of rotors. However, the working environment inside the turbine is extremely harsh, including high temperature, high pressure, high-speed rotation, and possible corrosion and wear. Therefore, we have designed this special high-temperature and wear-resistant LVDT sensor 4000TDGN-100-01-01 to meet these challenges.

Firstly, in terms of material selection, the non moving components of the displacement sensor 4000TDGN-100-01-01, such as the casing, iron core, and coil skeleton, have chosen high-temperature resistant alloys to resist high-temperature oxidation, creep, and thermal fatigue. The insulation layer and lead insulation between the coils use high-temperature stable insulation materials to maintain good electrical insulation performance and heat aging resistance. The parts in contact with moving parts, such as pull rods, guide sleeves, etc., are made of wear-resistant materials coated with hard alloy to reduce wear and extend service life.

Secondly, in terms of structural design, the key parts of the displacement sensor 4000TDGN-100-01-01 have been well sealed to prevent high-temperature steam, dust, oil stains, etc. from entering, affecting electrical performance and mechanical life. Add anti vibration and buffering components, such as spring supports, dampers, etc., to reduce wear caused by turbine vibration.

Special processing techniques are also essential. Vacuum pressure impregnation is applied to the coils, and high-temperature cured epoxy resin or other high-temperature resistant insulation media is used to fill the gaps between the coils to improve insulation strength. Conduct strict high-temperature aging tests to ensure that the sensor operates stably for a long time at actual working temperatures without any performance degradation.

Finally, redundant design and fault diagnosis are key to improving sensor reliability. Set up redundant LVDT sensors at critical locations, so that when one sensor fails or performs poorly, the other sensor can continue to provide accurate measurement data. Integrated sensor status monitoring function, real-time monitoring of sensor operating temperature, current, voltage and other parameters, using algorithms to determine whether the sensor is in normal working condition, and early warning of potential faults.

In summary, in order to ensure the long-term stable and accurate operation of the LVDT displacement sensor 4000TDGN-100-01-01 in the high-temperature and wear-resistant environment inside the steam turbine, it is necessary to comprehensively consider multiple aspects such as material selection, structural design, and special process treatment. In this way, LVDT sensors can exert maximum efficiency in the operation monitoring and control system of steam turbines.
