Schreiber SM20 Series LVDT Sensor | Ultra-Compact IP68
- Manufacturer: Schreiber Messtechnik
- Category: Displacement, LVDT, LVDT Unamplified, SENSORS
He LVDT sensor The Schreiber SM20 series represents the pinnacle of miniaturization in inductive displacement transducers. With an outer diameter of just 10 mm and constructed entirely of high-quality materials such as Ni-Fe alloy and stainless steel, this sensor is capable of operating in fully immersive conditions thanks to its high degree of protection. IP68. Its frictionless design guarantees a virtually unlimited lifespan, being the professional solution for metrology in confined spaces where total reliability is a non-negotiable requirement.
This LVDT sensor It offers exceptional sensitivity of 440 mV/mm and is compatible with any of the brand's conditioning electronics, allowing read displacements with micron precision even in environments with shocks up to 250g and severe vibrations. Its mechanical versatility, which includes spring-loaded or twin-piston pulser options, makes it the superior technological replacement for critical industrial applications that previously relied on brands like Solartron or HBM. Consult with engineering for system integration.
