Solartron Metrology Linear Variable Differential Transformer LVDT, AC Inductive Displacement Transducer, -40°C to 922936

Solartron Metrology 922936 is a high-precision Linear Variable Differential Transformer (LVDT), specifically engineered as an AC energised inductive displacement transducer for position measurement. This device utilizes a movable nickel iron core and three coil system - one for energisation and two for pick-up. When the primary winding is connected to an AC supply, the secondary coils produce voltages of opposite phase. At the centre position, equal and opposite voltages cancel out, resulting in zero output. As the core shifts, the voltage proportionally reflects the displacement through increased differential voltage between secondary coils.

The stainless steel body and friction-free push rod guarantee exceptional durability and reduced guidance accuracy requirements. The LVDT offers infinite resolution, high accuracy, and linearity, making it ideal for applications where precise position feedback is essential, such as automation systems, laboratory instruments, and manufacturing lines.

This model can operate reliably within harsh environments, withstanding temperatures from -40°C to 85°C. Its contactless design eliminates wear problems common in potentiometer-based sensors, ensuring long-term stability and minimal maintenance. A phase sensitive detector is required to demodulate the output signal, facilitating integration into advanced monitoring and control systems.

The Solartron Metrology 922936 LVDT stands out for its robust construction, reliable measurement, and adaptability to a wide range of industrial and laboratory tasks. Typical applications include precision linear position sensing in automation, machine calibration, test rigs, and dimensional gauging. Available with measurement ranges from ±1mm to ±50mm, the device supports flexible integration into equipment requiring fine displacement detection.
