What will be the reason for sudden spike in output to reach maximum and come back normal and also is these radar detect all the objects and human interference.
Hello, Thanks for your question. There can be different reasons for jumps to a higher level, for examples false signals from filling stream, build up or similar things. To determine where exactly the jumps are coming from the echo curve and the installation has to be checked.

Hello, thanks for your question. Upon a sensor failure (i.e. Loss of level signal) the current output can be set to fail high, which will send 21 mA creating a 100% full level indication at the PLC. The sensor can also be set to fail low, sending 3.6 mA indicating 0% at the PLC. The sensor can also be set to hold last known value. The output failure should be selected as needed for the application. If the output is digital, a failure message can be sent to the controller indicating there is a problem, since current output is not effected on the digital loops.

You should go into False signal suppression in future videos. Many customers usually have doubts about how to do False Signal Suppression.

So failure high of 21mA will indicate 100% or more on the DCS?
