what is the function of a zener diode ?

Answer Posted / kyle condran

Zener diodes regulate voltage. when placed in reverse bias is will have a constant voltage across it's terminals.

place it in parallel with a load and the load will receive a constant voltage regardless of the current flowing in the circuit as long as there is enough current to drive the diode.

since any parallel circuit will have the same voltage dropped across each parallel leg.

it does not act like a battery, the only component that acts like a battery is a capacitor, in that it can hold a voltage potential, but does not have much staying power when driving a current.

We are using Rosemount 5400 series Radar Level Transmitters in all types of Sump Applications having oily water hdrocarbon petrochemical nature. What we are facing the problem frequently is that always getting reading frezzed at some value. If we do power recycling , sometimes it is working . then making same freezing problem. If anybody faced before such type of problem and also having solution , Please give the answer.
