RPA-11 is an explosion proof amplifier and is intended for use with acoustic-emission system Ranis-11E, the supply voltage 8 V.Amplifieris mounted inside a sealed aluminum housingt hat provides protection rating at IP65 against dust and moisture.
At the bottom of the housing the strong magnet is mounted over electrical insulator. The isolatoris necessary to isolate the circuit ground from the bodyof the object under test. Magnet provides a clamping force up to14 kg on steel magnetic surfaces.
