This is recognized and used for triggering the switching signal. If there is medium between emitting unit and receiving unit, the signal is damped Soliwave is suitable as point level switch for controlling and counting all types of bulk solids
Level measurement | PPTX
Emitter and receiver interact with each other
Microwave barriers are used to detect all kind of bulk solids based on.
A potentiometer adjusts the sensitivity on the receiver so that the relay can switch at an approximate amount of obstruction By adjusting this potentiometer you can compensate for a certain amount of. Typical applications are the detection of bulk solids in silos, bunkers and crushers as well as of liquids in tubes and vessels The following relation between detection distance d and minimum distance between microwave barriers a applies to parallel operation of several barriers using emitters with selectable modulation frequency as.
The goal of this exercise is to turn on and test the microwave barrier using wavelength equal to several centimeters You have to position the transmitter and the receiver, connect them and adjust them. Many older microwave switches employ a diode detection technology but this new range uses the heterodyne detection principle which has the ability to obtain a proportional output to the power received. With the help of two microwave barriers, the overshoot of the upper (e.g
Product overflow) and the undercut of the lower point level value (e.g
Dry running of the discharge screw conveyor) can be. The emitting unit emits a continuous, low power microwave beam towards the receiving unit
