The combination of robust design and moderate system length makes this model versatile for many industrial applications with localized monitoring needs.
The 330104‑01‑05‑10‑02‑00 proximity probe is engineered for accurate, non‑contact measurement of shaft vibration amplitude and radial position relative to a fixed reference.
Using eddy current sensing technology, this probe generates a voltage signal proportional to the distance between the probe tip and a conductive shaft surface. Because it operates without physical contact, wear and maintenance issues due to probe‑to‑shaft friction are eliminated, ensuring long operational life.
This particular configuration offers a balance between sensing distance and installation flexibility. The 1.0 meter system cable supports typical control panel mounting distances, while the moderate case design simplifies installation and service.
Its rugged stainless steel body and IP67 environmental protection allow continuous operation in environments with dust, moisture, and mechanical vibration. The standard connector and threaded mounting make installation, cable routing, and future servicing straightforward.
The 330104‑01‑05‑10‑02‑00 proximity probe is used in a broad range of rotating machinery monitoring tasks, including:
Common sensing functions include:
The 1.0 meter cable length supports typical control cabinet mounting arrangements.
