Sensor TD-1-250-10-01-01 is a sensor specially designed to measure the displacement of the actuator of a steam turbine. It can monitor the displacement of the actuator, which is of great significance for controlling the operating status of the steam turbine, maintaining the normal operation of mechanical equipment, and preventing potential failures. By monitoring the stroke of the actuator in real time, engineers can ensure that the steam turbine operates in the best condition, thereby improving production efficiency and equipment life, while reducing maintenance costs and downtime.

The structure of sensor TD-1-250-10-01-01 consists of three coils wound on the same iron core, namely the primary coil and two secondary coils. The three coils are closely arranged along the axial direction and are encapsulated together in a non-magnetic shell. The iron core can move freely and is connected to the piston rod of the actuator. It moves linearly along the central axis of the LVDT as the stroke of the actuator changes.

Through the mechanical connection between the iron core and the moving parts of the actuator, as well as the change of the primary coil excitation and the secondary coil induced voltage difference, the sensor TD-1-250-10-01-01 can accurately and linearly convert the stroke displacement of the actuator into an electrical signal, thereby realizing real-time and continuous monitoring of the stroke of the steam turbine actuator.

The installation position of the sensor TD-1-250-10-01-01 is flexible and can be installed in any position, but it should be noted that in order to ensure measurement accuracy and avoid external interference, the sensor should be kept at a certain distance from the magnetic conductor or metal object, at least equal to the height of the mounting bracket. This is because placing magnetic materials or metal objects near the sensor may generate additional magnetic fields, which will affect the measurement results of the sensor.

In addition, the housing of the sensor TD-1-250-10-01-01 should not be close to magnetic fields and strong current wires. Magnetic fields may interfere with the sensor’s measurement, and strong current wires may generate electromagnetic interference (EMI), all of which may cause the sensor to output inaccurate data.
