ExMGZ100/200 – Intrinsically Safe Barrier

The ExMGZ 100/200.ATEX intrinsically safe barrier utilizes a zener limiter on the force sensor side. It controls the voltage to the force sensor while preventing over voltage.

A zener barrier is provided for each channel on the intrinsically safe side. Therefore the explosion proof area remains safe from hazardous voltage levels while still allowing the tension measurement or control to perform in the process. A control circuit ensures that the voltage drop of the zener barrier is compensated and it is guaranteed

that the full excitation voltage is provided to the force sensors.
