The Series PLS2 Paddle Level Switch is an electromechanical level switch designed
for level monitoring of bulk materials. The rotating measuring vane is driven by a
brushless synchronous motor at one revolution per minute and as product builds up,
the paddle rotation is impeded and the resulting motor torque activates the output
switch and stops the motor. The PLS2 is designed with the industry standard 1-1/4˝
male NPT connection and unit can be side or top mounted.
FEATURES/BENEFITS
• Torque adjusting mechanism eliminates the need for different sized paddles
• 3 sensitivity settings for spring force can be set for light to very sticky materials
• Brushless synchronous motor assures long term reliability and efciency
• Motor shuts ceases operation when paddle stalls
• Screw cover for easy access with no worries about losing bolts or screws
• Top or side mountable for added installation exibility
• Unaffected by the dielectric constant of the sensed material, making it superior to a
capacitance level switch for applications where the dielectric constant is too low,
where there is more than one material being used in one vessel, and when material
moisture content can change
APPLICATIONS
• Mining
• Food and beverage
• Silos
• Hoppers
