Overview
The CON021 is part of Emerson’s EPRO eddy current monitoring system, designed for non‑contact measurement of shaft vibration and displacement. It works in combination with sensors such as the PR6422, PR6423, PR6424, PR6425, PR6426, and PR6453, providing highly accurate monitoring of radial and axial shaft movement.
Moreover, the CON021 is widely used in steam, gas, and hydro turbines, as well as large compressors and pumps, where precise shaft position monitoring is critical for reliability and safety. Its fast response time (<15 μs) and wide frequency range (up to 20 kHz) make it suitable for dynamic machinery diagnostics.
Overview
The PR6423/01C-030 is part of Emerson’s PR6423 series of eddy current proximity sensors, engineered for non-contact shaft monitoring in critical rotating machinery. Paired with the CON021 signal converter, it provides high-accuracy measurements of shaft vibration, displacement, and eccentricity.
Its rugged stainless-steel construction, wide operating temperature range, and ATEX certification make it ideal for harsh industrial environments such as oil & gas, chemical processing, and power generation. This sensor is widely used in predictive maintenance programs where early detection of misalignment, imbalance, or bearing wear prevents major failures.
