Product Overview
The Bently Nevada 21504-00-40-10-02 is a high-performance proximity probe designed as part / the trusted 7200 Series. It features an 8mm probe tip and comes with a 40-inch integral cable, making it ideal for installations requiring extended distance between the sensing point and the proximitor. This standard mount probe is engineered for continuous monitoring / rotating machinery, providing precise non-contact measurements / shaft vibration and position.
Built to comply with API 670 guidelines, this probe is widely used in the oil & gas, petrochemical, power generation, and heavy industrial sectors. It works in conjunction with a proximitor sensor and extension cable to form a complete eddy-current proximity measurement system. Its rugged design, superior stability, and ease / installation make it a long-term solution for machinery protection systems.
