Hycontrol's budget range of vibrating probes is explicitly designed for use with dry products. Because these probes are only sensitive near their tips, build-up on the silo walls will not influence their readings.
The DP660 has a single solid stainless steel rod 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 it is not as sensitive to light materials. Therefore, only use DP660 probes on materials with a bulk density greater than 90 grammes per litre.
The DP660 vibrating probe is a low-cost solution for elementary applications with a history of success.
