LVDT Displacement Transducers are submersible to 7,500 ft.

Press Release Summary:

Designed for use in seawater and other submersible environments, including many corrosive liquids, LWU series transducers are available with stroke lengths from 0.5-4 in., linearity of ±1%, and operating temperature of -40 to 140°F. AC/AC unit LWU60X offers V/V output, while DC/DC models LWU61X and LWU65X provide outputs from ±5 or 0-10 Vdc and 4-20 mA, respectively. Made of 316 stainless steel, fully welded units with thru-hole design can endure 10 yr of submersion in seawater.

Original Press Release:

New Subsea LVDT Series Is Submersible to 7,500 ft.

Amherst, NY - The Series LWU is a family of submersible LVDT displacement transducers available in either DC or AC versions. These units are specifically 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 deg.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 heavy duty construction makes these units able to endure the most rigorous applications including 10 years submersion in seawater at a depth of 7500 ft. (2300 m). The free unguided armature design allows non-magnetic fluids to enter the transducer body without affecting the operation of the transducer. In addition, this thru-hole design helps overcome the problems associated with marine growth.

The LWU Series is available now from Stellar Technology, with prices starting a $1,430. A variety of cable lengths and customer-specified connectors are available.
