Kaiser Raman Pilot-E Probe

Offering simplified, reduced cost installation in the process environment

The Kaiser Raman Pilot-E probe is a rugged, process insertion probe with no sample handling system. Its single cable design streamlines installation, eliminates risk scenarios, and minimizes installation cost for long fiber runs in the process environment. The Pilot-E probe utilizes a hybrid electro/optical fiber cable assembly to carry the analytical signal and the safety interlock in a single easy-to-install cable.

The Pilot-E probe is ideally suited for use in chemical plants and refineries to measure batch or continuous flow production. It is also highly effective for use in pharmaceutical manufacturing facilities for glass-lined reactors as part of a Quality-by-Design (QbD) solution using Process Analytical Technology (PAT) analyzers. For direct measurements in cryogenic fluids, an optimized cryogenic version of the Pilot-E probe is available.
