Pulsarpoint 300 Pulsar Rotating Paddle Switch

Pulsarpoint 300 is a rotating paddle level switch for level measurement and switching on bulk solids. The paddle's rotation is interrupted when material reaches the paddle, causing a clutch to disengage the motor. This in turn actuates a relay allowing an alarm signal to be switched. This may be used to signify a material level as being high, intermediate or low depending on configuration chosen.

The Pulsarpoint 300 utilises a polycarbonate housing, sealed to IP66. The process connection is of the same material, with a polypropylene double blade paddle as standard which can be easily converted to a single blade.
