DTR**1Z The Thermo Scientific Ramsey Granuflow
DTR **1 and DTR **1 are low-cost, noninvasive, microwave-based
instruments that detect and monitor flow/no-flow conditions of
bulk solids in pipelines, ducts and air-slides, as well as at
transfer points of chutes, conveyor belts and bucket elevators.
Used for automation purposes, they efficiently optimize the use
of machinery and energy by switching process equipment on or off
as required. The RamseyTM Granuflow DTR **1 and DTR **1 have no
moving mechanical parts, which eliminates wear and makes the
instruments maintenance-free and trouble-free.
Principle of Operation
The Ramsey Granuflow DTR **1 utilize the Doppler Effect. They
measure the difference between emitted and reflected microwave
frequencies. Their electronics emit a signal that is reflected by
moving material. When the material is in motion, the returned
signal is either higher or lower in frequency than the
transmitted signal. No motion is present if the returned signal
is the same frequency as the transmitted signal. Changes in the
received microwave energy, due to things such as build-up in
front of the antenna, do not affect flow/ no-flow detection.
These detectors produce microwave energy at a level of 0.*5
mW/cm2 (measured at the antenna horn), which is a much lower
level than the international safety standard of *0 mW/cm2. They
are certified to FCC**5F.
Typical Equipment Applications
