The DM series of DC/DC linear transducers cover the range 2.5mm to 50mm and are intended as a general purpose instrument. As with all other Sensonics LVDT's they are robustly housed with impregnated coils and internally potted so that they are suitable for use in the majority of industrial applications.
Uses include extensometers, hydraulic actuators, float positions, thickness measurements, geophysical parameters, earth movements ...
The series is available with the lightweight core supplied as a basic unattached item (DMF) or with the core attached to an extension rod (DMG) or with the core and extension rod captive and spring loaded (DMS).
Other DC-DC series in the Sensonics range are:
DF Series 15mm to 50mm
DE Series ± 25mm to ± 300mm
The DF Series has a larger bore to core clearance, but a heavier core and the DE series has a heavier core and extension assembly which makes it more robust for its
longer stroke capabilities.
12v or 24v models in the DM series are available in any of the three configurations giving 30 standard options.
