The GCNA08 series of high-precision pen-type LVDT position sensors feature multiple upgrades over the MBP8 series. The GCNA08 achieves linearity <0.1% (full stroke), with surface-treated housings offering enhanced corrosion resistance. The internal precision anti-friction structure ensures a service life not less than 100 million cycles.

The GCNA08 series pen-type LVDT, is designed for high-precision industrial measurement, quality control and SPC statistical process analysis applications. The product adopts a structure combining linear ball bearings and a hardened non-rotating measuring axis, effectively reducing radial play and edge load interference, and realizing repeatable positioning accuracy of up to 0.15μm.

The LVDT measuring head has a built-in frictionless structure, and its core is directly connected to the measuring shaft, which can output a voltage signal that is linearly proportional to the displacement, effectively avoiding measurement errors caused by mechanical friction or hysteresis. The output signal is compatible with standard signal conditioning equipment and can be conveniently connected to display instruments or computer data acquisition systems.
In conventional applications, the measuring shaft is continuously pushed by a spring with a force of approx. 70 grams, which extends it outwards from the mechanical zero point and ensures stable contact with the object to be measured. The entire measuring mechanism, includes bearing, measuring shaft and LVDT, is integrated within an 8 mm compact and robust stainless-steel housing. The end is equipped with a flexible polyurethane protective cable, which is resistant to stretching and abrasion and guarantees stable signal transmission to the conditioning system.
GCNA08 series LVDT position sensors are the ideal solution for precision displacement measurement with their miniaturized design, high accuracy output and strong anti-interference capability.
