Probe Pendulum for Eddy- Current Sensors

Transcription

1 PR647 Specifications Sheet Probe Pendulum for Eddy- Current Sensors The Probe Pendulum for eddy-current Sensors is designed for critical turbomachinery applications such as steam, gas and hydro turbines, compressors, pumps and fans to measure axial shaft dynamic displacement. It allows measurements with huge measuring ranges in unfavorable environmental conditions and at measuring collars where it is not possible to realize direct measurements with eddy- current sensors, due to the mechanical conditions.
