G-Type

The G-Type of Analogue DC/DC Displacement probes are based on the LVDT sensing principle and feature a high accuracy, long life linear ball bearing (as AX-Series). All models incorporate a Linear Variable Differential Transducer (LVDT) as the measuring element, together with high performance conditioning electronics for low noise and superior linearity while being able to cope with a wide supply range. The G-Type Analogue Displacement probe range has evolved from its predecessor DG series with marked improvement in features and performance. This product offers a perfect solution for various displacement applications with a good linearity and repeatability.

Displacement Sensors | Miniature Displacement

The DF dc miniature displacement sensor has a friction-free core and the DFg has a free guided core incorporating Delrin bearings. All types incorporate a linear variable differential transformer (LVDT) as the measuring source together with oscillator, demodulator andfllter providing a self-contained unit accepting a DC input and providing a DC output relative to armature position.
