Unique Vibrating Level Sensor
Ideal For Dust Collection Systems
Dust collection systems require reliable monitoring
of high level material conditions in their hoppers
for safety and proper operation. Material high
level backup conditions in the dust collector hopper
can create conditions that can damage the equipment
and can lead to fires or explosions in some cases. These
dust collection systems are used for collecting a variety
of materials. Many of these materials can be
very light in weight because of the small nature and
density of the dust particles. The range of bulk
density and dielectric constants of materials collected
varies widely. This can be challenging for most
level sensor technologies, but not for the unique Model
PZP vibrating rod sensor from Monitor Technologies. Monitor
is pleased to announce that its Model PZP vibrating
point level sensor is capable of detecting bulk solid
materials with a density as light as 1.0 to 1.5 pcf
(pounds per cubic foot) all the way up to 100 pcf. In
addition, the PZP does not require calibration
and uses a unique diamond shape single element that
is immune to material packing and bridging, unlike
traditional tuning forks.
The Model PZP vibrating point level sensor uses dual piezoquartz crystals. These
crystals respond to electrical excitation by vibrating, which results in the
vibration of the sensing element at about 280Hz. The uniqueness of the
PZP's diamond shape sensing element and electronics provides the sensitivity
to detect very lightweight materials, in addition to heavier materials. This
ultra-lightweight sensing capability down to as light as 1.0 - 1.5 pcf make this
level sensor ideal for dust collection applications.

The
SafePoint rotary paddle level switch with a self-validating design
detects material presence plus continuously monitors its own ability
to function. The analysis includes sensor health and system power
failure, which makes the SafePoint truly “fail-safe”.
The SafePoint incorporates patented use of Hall-Effect technology,
dual outputs to indicate both material presence and unit health,
and microcontroller technology to continuously protect bulk solids
processing and storage from the consequences of unknown sensor
failure by providing immediate indication of a sensor failure
and confirmation of proper operation.
Other practical features of the SafePoint include rugged construction,
motor shut-off when paddle becomes impeded to maximize motor life, twist On/Off
cover for bolt free removal, and local status indicating light (except hazardous
location models)
A practical application for the SafePoint would be to use this "true"
fail-safe product if undetected sensor failure could result in a
catastrophic process problem.
