Level switches for dust collectors and more

By Chemical Engineering | July 1, 2020

Automation Products Inc. – Dynatrol Div.

The DJ level switch (photo) provides high- or low-point level detection of bulk solids. The DJ detector operates successfully on baghouses, cyclone separators and above airlocks. Consistent results have been achieved on chemical powders, minerals and many other granulated materials. This level switch is approved for Class III services, as well as for Class I, Groups C & D and Class II, Groups E, F & G. The level switch is mounted through a 3/4-in. half-coupling at the point of desired level detection. — Automation Products Inc. – Dynatrol Div., Houston
