Daniel Rivera –
We ordered this proximity probe as a direct replacement for an existing 3300 XL unit on a centrifugal compressor. The probe was new and matched the required part number exactly. Installation was straightforward, and the system returned to normal operation without additional adjustments. Delivery was completed within a short lead time, which helped reduce maintenance downtime. Based on our experience, the product functioned correctly and met OEM expectations.
