LTR52 Self-Adjusting "Smart" Radar Level Sensor
Brand: Intempco Controls, Inc
The LTR52 Series radar level sensors are designed for applications requiring non-contact level measurement, in which ultrasonic level measurement is not acceptable.
The LTR52 Series radar technology can be adjusted for variables such as materials to be measured, vessel configuration, and system interface.
These sensors are ideal when vapor or dust prevents ultrasonic-wave measurements.
The LTR52 Series radar sensors can detect the level under a layer of light dust, but if the dust particle size increases, or if the dust gets thick, they will no longer detect the solid level.
Instead, the level of the dust will be measured. Internal piping, deposits on the antenna, multiple reflections, or reflections from the wall can interfere with the proper operation of the radar sensor.
Other sources of interference are rat-holing and bridging of solids, as well as angled process material surfaces that can reflect the radar beam away from the receiver.
