LC412-IS, twist-lock
termination shown.
The LC412-IS Series intrinsically
safe load cells are FM rated
intrinsically safe for use in
hazardous locations. They are
available with 5 different electrical
terminations. Three connector
options and 2 cable options, one of
which is a submersible waterproof
cable. Standard models have an
amplified 4 to 20 mA output for
uni-directional applications and a
4-12-20 mA output for bi-directional
applications.
