Submersible Transducers

April 1, 2010

Stellar Technology (Amherst, NY) offers the Series LWU submersible LVDT displacement transducers available in either DC or AC versions. The units are designed for use in sea water and other submersible environments, including many corrosive liquids. The LWU Series features unguided armatures with stroke lengths from 0.5" to 4" and linearity of ±1%. Operating temperature is from -40 to 140 °F.

The LWU60X is an AC/AC unit with v/v output. The LWU61X and LWU65X are DC/DC units with outputs of ±5 Vdc or 0-10 Vdc and 4-20mA, respectively. The LWU units are made of 316 stainless steel, and are fully welded. The units can endure 10 years of submersion in seawater at a depth of 7,500 feet. The unguided armature design allows non-magnetic fluids to enter the transducer body without affecting the operation of the transducer.
