Pulsarpoint 200 Pulsar Vibrating Level Switches

Pulsarpoint 200 Pulsar Vibrating Level Switches is a vibrating level switch for bulk solid applications. When solids material comes into contact with the vibrating probe, the frequency of oscillation changes. This is detected and a signal generated to provide a changing relay output. May be used to signify a material level as being high, intermediate or low depending on the configuration chosen.

The design of the thin blade profile and the frequency of oscillation ensure that the probe is able to resist material build up, often associated with tuning fork designs. This provides a long, trouble-free operation.

The Pulsarpoint 200 Series is suitable for most granular products with a bulk density of 20g/litre or more. A relay output is standard. The electronics are mounted in a diecast aluminium housing. The process connection and probe are in stainless steel. An adjustable sensitivity setting allows easy adjustment to suit the material being monitored.
