The 28047, also known as a Linear Variable Differential Transformer (LVDT), is an electromechanical device used to measure displacement. The device consists of three main components: a primary-coil former, usually made of ferrite-core material; a secondary-coil former, which is sometimes made of iron; and the center core, which is typically constructed from a stainless steel or brass. LVDTs are often utilized in diagnostic and control systems such as vibration monitoring, fault detection, and motion sensing applications.

The primary coil former is triggered by an AC voltage, which drives a current through the primary coil. This current is then directed to the secondary coil former, which is positioned slightly off-center with respect to the primary coil. Any displacement of the center core in relation to the two coil formers causes the current in the secondary coil to be modified. Through a process of analog-to-digital conversion, the modified current can be used to accurately measure the corresponding displacement.

The 28047 has a number of advantages over other sensor systems. It is highly accurate over a wide range of displacement with minimal hysteresis, which is the tendency of the output signal to remain slightly offset from the exact measured value. The device is also highly reliable with a temperature range of -20° to +80°C, and its long-term stability has been tested to ensure its continued accuracy over time. Furthermore, the sensor is extremely resilient with its stainless-steel and aluminum construction.

The 28047 offers a number of application opportunities over its peers. In industrial settings, the 28047 is frequently used for position sensing, such as measuring piston travel or detecting the opening of a door. The device can also be used for motion monitoring, such as measuring the vibration of a machine. Additionally, the 28047 is well-suited for shipping and aviation operations due to its resistance to vibration and other physical trauma. It is also used in medical scenarios to measure patient posture and movement.

The 28047 has a number of advantages that ensure its continued popularity with industrial buyers and end users. It is highly accurate, reliable, and resilient to environmental factors, which ensures its continued accuracy and measurement performance over time. Its wide range of possible applications and the ease with which it can be incorporated into various systems make the 28047 a preferred choice for displacement sensors.
