Description
1. lntroduction
(contd.)
An impact-resistant
molded shell ensures
an extended service life. To
eliminate hose
twisting, the modelfeatufes
a
360-degree
swivel
connector.
Depending
upon the applicator design,
the handgun may use either
a
preset
temperature
sensor or an RTD
(resistance
temperature detector)
sensor. RTD
sensing allows for
precise
temperature control by reducing
temperature fluctuations that could
affect flow and cause char formation.
A wide operating
range of 65 to 230
"C
(150
to 450
'F)
provides
additional application versatility.
For
handling very
thick adhesive, the AD-31 LBS extrusion
handgun
incorporates
a large ball-and-seat
and
larger
flow
paths.
