Draw Wire Linear Sensors.
Penny + Giles has launched a new range of draw-wire
linear sensors. DLS is a compact sensor that provides
accurate measurement in a range of strokes up to
5000mm and is suited for use where space is a
constraint or where traditional linear potentiometers
are not suitable.
There are three sensors in the range:
DLS-P60 has a measurement range from 100 to 1500mm;
DLS-P96 has a measurement range from 2000 to 3000mm;
and DLS-P1 15 has a measurement range from 3000 to 5000mm.
All are encased in a high strength aluminium housing and sealed
to P65 for use in harsh environments. They provide virtually infinite
resolution with a long life cycle and can withstand temperatures
from -20 to 80°C. The highly flexible stainless steel measuring wire
is wound onto a drum with the aid of a long-life spring motor. The
winding drum is linked axially to a multi-turn potentiometer,
incremental encoder or absolute encoder. Linear movement is
transformed into a rotation by the draw-wire principle and converted
into a proportional analogue signal or to countable increments.
The sensors can be supplied with a choice of analogue outputs
(potentiometer, 0-10Vdc voltage or two-wire 4-20mA current) or
digital outputs provided by encoders.
The sensor can be orientated in any direction and has mounting
grooves on four sides of the housing to make the sensors easy to
install. A range of accessories is also available to assist the user
during installation including.
