CASE STUDY PLASTIC INDUSTRY

Lorandi Silos is a Brescia-based company founded in 1952 and run by the same family for three generations. In the early 1980s it took its first steps into the world of plastics, coming to develop high skills in the storage and transportation of material in the form of granules, ground flakes or powder. By now Lorandi silos and plants can be found all over the world, and the push for internationalization has created several international establishments including North America, Spain and India.

CUSTOMER REQUIREMENT

Lorandi Silos needed level sensors:

• with paddles capable of detecting different types of materials with different densities;
• with power source that would make them adaptable to different types of systems;
• with Atex certification for some specific applications.

To meet the requests of Lorandi Silos, CAMLogic proposed the PFG05 rotary paddle level sensor, which is widely used and appreciated for its reliability and versatility. The die-cast aluminum body makes it suitable even under heavy working conditions and continuous rhythms. It has a threaded connection to the G 2" ½ process or with a mounting flange. The wide choice of helixes allows the level switch to detect materials with densities between 0.1 and 2.0 kg/dm3. The instrument can also be customized with special lengths and electrical accessories.

• Available voltage ratings: 115/230V or 24/48V – 50 … 60Hz (AC) and 24V (DC).
• Standard version with faston connectors.
• Paddle terminals or self-locking spring terminals are available on request.
• Voltage monitoring: to remotely check that the sensor is energized correctly.
• Double contact: additional potential-free contact for monitoring the automatic parts of the system.
• Rotation control: enables sensor operation to be monitored remotely.
• 4 RPM: increased rotation speed to reduce trip time.
• Low temperatures: enable the instrument to function down to -27°C.
