Designed
for use while submerged under fresh water and most other non-corrosive
liquids and gases, these LVDT's are extensively used in industrial and
R&D applications. They are designed to operate in pressures of
up to 10 bar using the standard connector (optional electrical
terminations allow up to 206 bar).
The
welded stainless-steel body is hermetically sealed and has a cable exit
which is double-sealed using an internal rubber gland plus a polyolefin
shrink tube covering the cable and transducer body. An alternative
MI stainless-steel sheathed cable option is available for use under high
liquid pressures (as in soil testing apparatus, hydraulics, vessel
studies, etc.)
General Specifications are
given below.
