Description

Zener Barrier:

The typical zener barrier offers a galvanic connection between the mounted devices such as p/I converters, RTDs, PT 100, Thermocouples in the flammable hazardous area etc and the instrumentation circuits outside the hazardous area. It is therefore necessary to limit the maximum value of the current with the help of a resistor and a fuse. This results in a natural voltage drop inside the barrier, sometimes not allowing sufficient voltage to drive a transmitter, especially if long cable lengths have to be connected between the transmitter and the zener barrier !
