Jewell has a 40+ year history of providing
precision force

-balanced inclinometers and is

pleased to provide MEMS parts with the same

attention to detail that our customers demand.

The

JDI-100/200 series is a digitally temperature

compensated inclinometer available in single (JDI-100)
and dual (JDI

-200) axis configurations. This presents a

robust and rugged design for industrial use, but with
the benefit of low

-cost MEMS technology.
