The wide product selection is a major reason why Monitor's TrueCap� RF capacitance probe is a popular and versatile point level sensor for a large range of powder and bulk solid, liquid and slurry applications. Optional versions include high temperature, hazardous location, stub probe, food grade probe, quick-connect process connection, high level sensing with pipe or cable extensions and more. 

For instance, the stub probe model (a shorter version of the standard probe) allows the TrueCap to be used in tighter spaces, used to limit mechanical forces placed on the probe from material flow or to keep the probe out of the main material stream. In addition, the TrueCap design provides automatic immunity to material build-up on the probe by its driven shield design. Options for the TrueCap� stub probe model include a 3/4 inch / 1-1/4 inch combination process connection for replacement or new installations and a probe with white nylon insulator for food grade applications.

The photos above show a stub probe model of the TrueCap� installed in the unloading pit of a grain handling elevator set-up. The TrueCap sends a signal based on the system design requirements that involves the unloading pit connected to a drag conveyor that feeds the bucket elevator to move the grain to a silo. In this situation, the TrueCap stub probe version was chosen because the shorter probe will help to limit the amount of mechanical force on the probe from the material (grain) flowing into the pit.
