Hycontrol's budget range of vibrating probes has been explicitly designed for use with dry products. Because these probes are only sensitive near its tip, build-up on the silo walls will not influence their readings.

The DP660 has a single solid stainless steel rod which is vibrated by the piezoelectric element. It is a small, low-cost unit designed for very simple switching applications.

Because of its small size, it is ideal for use in small hoppers containing granular materials or pellets, like plastics, food or grain. Still, the circular construction of the DP660 means that it is not as sensitive to light materials. Only use DP660 probes on materials which have a bulk density greater than 90 grammes per litre.

The DP660 vibrating probe is a low-cost solution to elementary applications, with a history of success.
