VLS Vibrating Rod Solids Level Switch by Delta Mobrey is the perfect solution for single point level switching in free flowing solids across a wide density range, from fine powders to grains. A single rod design provides the solution to tuning forks which may become blocked or bridged.
VLS Vibrating Rod Solids Level Switch Series:
- The Mobrey product range provides reliable point level detection in a variety of dry solid applications
- The Mobrey Series PLS is a paddle rotating level switch that detects high or low levels of most free-flowing
bulk solids and powders - The Mobrey Series VLS vibrating rod level switch has a single probe design that eliminates the clogging
and ridging problems associated with forks
Series VLS vibrating rod level switch
The vibrating rod level switch is the perfect solution for single point level switching in free flowing solids across a wide density range, from fine powders to grains. A single rod design provides the solution to tuning forks which may become blocked or bridged.
The vibration rod is energized and kept in resonance by an electronic circuit. When covered by material, the damping of the vibration is detected by the electronics which initiate the switching of the output relay after a built-in programmable time delay.
Vibrating Rod Solid Level Switch VLS Series:
- The Mobrey VLS may be used in a hazardous area with flammable dusts.
- Installation of the Mobrey VLS shall be carried out by suitably trained personnel, in accordance with the applicable code of practice.
- The Mobrey VLS is suitable for installation across the boundary between an area that specifically requires Equipment Protection Level Da (Zone 20) and an area that specifically requires Equipment Protection Level Db (Zone 21). The probe (and extension) is only to be installed in Zone 20 (EPL Da).
- Inspection and maintenance of this equipment shall be carried out by suitably trained personnel, in accordance with the applicable code of practice. Only approved spares supplied by the manufacturer or approved agent can be used.
- If the Mobrey VLS is likely to come into contact with aggressive substances, it is the responsibility of the user to take suitable precautions that prevent it from being adversely affected, thus ensuring that the type of protection is not compromised.
