I
ncorporated in the design of the PLS is a magnetic drive that is time proven by
d
ecades of use in our Mark Series valve position indicator product line. A synchro-
n
ous motor rotates the paddle utilizing a magnetic drive. As product builds up the
paddle is impeded from moving and the resulting motor torque activates the output
switches and stops the motor. A spring mechanism reactivates the motor and returns
the switches to normal state when the product no longer impedes the paddle rota-
tion. Weatherproof models include a bright red LED switch status indication light.
Standard construction is weatherproof with explosion-proof optional, and the unit can
be side or top mounted. A high temperature option is available for use with media up
to 500°F (260°C). The PLS is designed with the industry standard 1-1/4˝ male NPT
connection and mounting flanges.
FEATURES
Magnetic drive that isolates and completely seals the control head from the
process and environment preventing material or dust from entering the control
head.
Motor shuts-off when paddle stalls increasing motor life, preventing motor
burnout, and decreasing power usage.
Slip clutch design enabled by the magnetic drive that prevents damage to motor
and drive mechanism from sudden or excessive loading on the paddle.
Status indication light on weatherproof models. Light is on the side of the enclo-
sure making it easy to view.
Screw cover on the enclosure for easy access with no worries about losing bolts
or screws.
Modular design to allow field installation of any paddle, flanges, shaft extensions,
or shaft guards.
Flexible coupling available for protection of the paddle and drive from side loads,
surges or impacts. Recommended for top mount applications with shaft extension
and applications with large or heavy materials.
