company history and characteristics

Coima was founded in 1982 in Fano (PU), in one of the most important districts for industrial processing and furniture production. It produces, in fact, systems for waste removal, filtering and storage of residues obtained from wood processing; and in recent years it has also specialized in the design and installation of systems for industrial painting.

COIMA needed level indicators: 

  • easy to assemble and connect;
  • with power source that would make them adaptable to different types of installations;
  • ATEX certified, in relation to where they operate.



CAMLogic was able to identify for COIMA the PFG05 model, a rotary paddle level sensor with a die-cast aluminum body and threaded connection to the G 2" ½ process or with a mounting flange. Also suitable in potentially explosive atmospheres due to the presence of dust, according to the most recent ATEX standards. 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.

Rotary paddle level sensor - PFG05


After an initial analysis of the client, it was found that high voltage would not meet the operation of the systems built by COIMA. So two versions of the same indicator were chosen and had different electrical customizations, PFG05 V.24/48ca and PFG05 V.24cc.

In fact, for CAMLogic, it is extremely important to provide electrical level sensors that can be applied to different types of systems, so adapt the electrical options as well. The electrical part of the entire range of PFG05 level probes can be supplied with different voltage ratings and numerous optionals:

  • 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 indicator is energized correctly.
  • Double contact: additional potential-free contact for monitoring the automatic parts of the system.
  • Rotation control: enables indicator 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.

"We work with low voltage for safety," Paci explains, "plus the engineering department prefers this type of level sensor because they have found more guarantees over the years."
