Vibratory
Level Indicator Is Ideal For Materials With
Lower Bulk Densities
The Model
PZP vibrating style point level sensor provides
exceptional sensitivity for detecting bulk solid
materials with a density as light as 1.25 lbs./ft.3 (pounds
per cubic foot) where other sensor technologies might
be ineffective. Additionally, 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. Plus, it has no
mechanical moving parts.
The Model PZP is also designed for versatility. It's
ideal for situations where the range of bulk density,
particle sizes, humidity levels, and/or dielectric constants
of the materials being stored or collected (dust collection
systems) varies widely. This can be a challenge for many
level sensor technologies; however, the PZP is capable
of detecting bulk solid materials with a density as light
as 1.25 lbs./ft.3 all the way up to 100 lbs./ft.3.
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. Applications
for use include high and low level indication and as
a back-up for dust collection systems. Typical materials
include plastics, cement, fly ash, chemicals, lime, clay,
sawdust, food, flour, rice, cereal and more.

Microwave solids flow detectors can
be used in a variety of applications including feed mills & grain processing,
consumer foods (cereal, sugar, cocoa, coffee), chemicals & pesticides
and more. For example, one company uses Monitor’s Model SFD-2
solids flow detector to verify the flow of feed pellets through their
various transport lines which involves a process where a horizontal
screw auger is conveying pellets over to a vertical gravity chute. The
chute then directs the pellets to a process down below. They have
carefully placed the SFD-2 so that it detects the pellets as they
fall directly across the sensor face. (See Below)
The Model SFI and SFD-2 line of solids flow detectors
from Monitor Technologies, LLC provide analog or relay outputs
to indicate the flow / no-flow condition of powder and bulk solids
materials in chutes and pneumatic conveying lines. Using
microwave Doppler radar technology these units are non-invasive
plus extremely reliable and rugged to withstand the rigors of the
installation and your process extremes. From automated systems
with pneumatic lines to gravity chutes, solids flow monitors can
help to improve process performance. They can assist in detecting
flow problems, as well as, enhance the level of automation at a
facility like turning a conveyor on or off.
