Solartron Metrology Miniature DC Energised Displacement Sensor 922937, Operating Temperature -20°C to 80°C

The Solartron Metrology 922937 displacement sensor is a miniature, DC energised device designed for highly accurate displacement measurement applications. It operates effectively across a temperature range from -20°C to 80°C, ensuring reliable performance in various industrial and laboratory environments.

This sensor incorporates a built-in electronic oscillator and demodulator that produces a DC output signal proportional to the position of a movable nickel iron core within the sensor. The DFg series features separate coil and electronic assemblies with a free core fitted with a polyacetal homopolymer bearing, facilitating smooth guiding and reducing wear.

The DG2.5 variant includes a non-rotating spring-loaded armature running in precision linear ball bearings, providing enhanced precision. Its construction as a Linear Variable Differential Transformer (LVDT) includes three coils: one energisation coil and two pick-up coils. Driven by a sine wave, it generates output amplitude and phase related directly to the core's position, requiring a phase-sensitive detector for signal demodulation.

Main advantages of this LVDT sensor include infinite resolution, high accuracy, excellent linearity, and zero friction, distinguishing it from potentiometers which suffer from wear issues. Models are available with measuring ranges from ±1mm to ±50mm, making it highly versatile for precision displacement sensing.

This unit is particularly suitable for applications in industrial automation, precise laboratory instrumentation, manufacturing process control, and metrology tasks where exact linear position measurement is critical. Its UK origin underscores its adherence to rigorous quality and manufacturing standards.

Operates between -20°C and 80°C providing broad environmental resilience. Constructed with polyacetal homopolymer bearing to reduce wear and improve longevity. LVDT technology offers infinite resolution and no friction, optimal for precision tasks.

Compact and miniature design enables integration into tight spaces and specialized equipment. Manufactured in the United Kingdom with high-quality material standards. Offers precise core-position output ideal for sensor IC and motion sensor applications.
