Disc RF Admittance Level Switch – DRFA

Disc RF Admittance Level Switch (DRFA) is a rugged and reliable point level switch specially designed for detecting blocked chutes and material flow obstruction. It is side-mounted at the lower level of chutes, hoppers, or tanks to ensure early detection of material buildup.

The RF admittance technology makes the switch immune to material coating and buildup, ensuring consistent and accurate performance even in harsh industrial environments with dust and abrasive materials.

Reliable blocked-chute detection solution for heavy-duty bulk material handling.
