The AS75I and AS150I are active sensors with very high sensitivity for measurements on GIS, transformer tanks, or cable joints. They come with a built-in 40 dB preamplifier and can be connected to the RPA1D, RPA1F, RPA1G, or directly to the AIAcompact, ICMsystem, ICMcompact, or ICMmonitor.

The sensor fixture SFX1 is suited to secure the acoustis sensors on a GIS. The magnetic sensor fixture SFX2 and the sucking fixture SFX3 are for temporarily mounting of the acoustic sensors on a transformer tank.
