Penny + Giles is a world leader in the
manufacture of
linear and rotary potentiometers
for
positioning measurement and joystick
controllers.
 
Penny + Giles is a leading designer and manufacturer of specialist  equipment,
position sensors and control hardware for industrial, military and aerospace
markets. The product range includes linear and rotary position sensors; joystick
controllers; draw wire (string pots); tilt sensors (inclinometers) and associated
signal conditioners. They are used to measure
stroke or displacement or
positioning often in highly hostile environments.

Penny + Giles' success in world markets results from innovative technology,
creative designs, manufacturing excellence and interactive customer support.
For more than 50 years Penny + Giles has built an unsurpassed store of
experience which is supported by high precision engineering.

A wide variety of technologies are used to build the products including
potentiometric, inductive, Hall effect, Eddy current and 3D-MEMS ( Micro-
ElectroMechanical Systems). These products are in used in aerospace,
construction, defense, marine, material handling, mining, motor sport,
off-highway, power generation, process control, robotics, timber and forestry, and
transportation industries.

Draw-wire linear (string-pot) sensors

Draw-wire or string-pot linear position sensors measure the linear
movement of a component via a highly flexible steel wire which is
wound onto a drum by a durable spring-driven motor. The winding
drum is linked axially to a multi-turn potentiometer, incremental
encoder or absolute encoder. A linear movement is transformed
into a rotation by the draw-wire principle and converted into a
proportional analog signal or to countable increments. Versions
with integral electronics produce voltage and current signals at the
output which are proportional to the displacement. Draw-wire or
string pot sensors are simple in application and represent an
economical investment. There is a significant advantage in that,
despite their compact size, the sensors can cover large
measurement ranges.
