The position of the opening of each main steam valve, main regulating valve, and other valves in the steam turbine unit needs to be fed back to the control system in real time, in order to achieve automatic control and regulation of the steam turbine. The commonly used displacement sensors for valve position detection in steam turbine systems currently include LVDT displacement sensors such as HTD-400-3.

LVDT displacement sensor HTD-400-3 has high accuracy, strong anti-interference ability, and low cost. The control system based on displacement sensors can maintain efficient operation for a long time without pollution or mechanical damage, greatly improving the efficiency, safety, and automation level of the process control system.

In addition to being applied in steam turbine control systems, LVDT sensor HTD-400-3 can be used to measure precise data such as the elongation, vibration frequency, amplitude, thickness, and expansion of objects. Specifically, it can also be used for positioning machine tools and hydraulic cylinders, as well as controlling roller gaps and valves.

Except for HTD-400-3 LVDT Position Sensor, Yoyik have other types of spare parts for power plant steam turbines.
