The displacement sensor HTD-300-4 sensor is one of the HTD series displacement sensors, designed for measuring the stroke of turbine actuators. The “300″ in its model number usually indicates the measurement range or related specifications, while the “-4″ may refer to a specific configuration or version. This sensor uses the differential transformer principle to convert the mechanical quantity of linear movement into electrical quantity, thereby achieving accurate measurement and control of displacement.

Working principle

The HTD-300-4 displacement sensor works based on the differential transformer principle (LVDT). This principle enables the sensor to convert mechanical displacement into electrical signals. Specifically, when the object being measured is displaced, the movable iron core in the sensor moves accordingly, causing the inductance of the coil to change. By measuring this inductance change, the size and direction of the displacement can be accurately determined. The LVDT principle has the characteristics of high precision, high repeatability and good linearity, ensuring the reliability of displacement measurement.

Application Fields

The HTD-300-4 displacement sensor is widely used in a variety of occasions that require high-precision displacement measurement, especially in steam turbines for actuator stroke, hydraulic cylinder piston positioning, valve position detection, etc. Its excellent performance and reliability can meet the needs of various industrial applications and improve production efficiency and product quality.

Installation and Maintenance

When installing the HTD-300-4 displacement sensor, ensure that the sensor is installed on a plane and avoid being close to magnetic metal. The general distance is more than 20mm, and it should not be close to strong magnetic fields or strong currents. During use, be careful to avoid bending forces, as this will affect its sensitivity. The connection of wires is also a focus that requires daily maintenance and attention. If a broken wire is found at the welding point, it must be handled in time.

In short, the displacement sensor HTD-300-4 has become an ideal choice in the field of industrial displacement measurement with its high precision, high reliability, wide temperature range and excellent environmental adaptability. By accurately measuring displacement, it provides a strong guarantee for the safe, stable and efficient operation of equipment such as steam turbines. In actual applications, correct installation, use and maintenance of HTD-300-4 can ensure its long-term stable operation and optimal performance.
