330876-01-90-01-05 Product Introduction
It provides reliable shaft monitoring. This probe uses eddy current technology. It senses target distance without any contact. Many engineers trust the 3300 XL series. The Bently Nevada 330876-01-90-01-05 operates in high-temperature areas. Specifically, it withstands up to 200°C (392°F). Its long case length supports deep mounting holes. Furthermore, this model has a 5mm probe tip diameter. It delivers a linear measurement range. Therefore, you get accurate vibration and position data.
Core Value
This probe significantly improves machine protection. Firstly, it detects early bearing wear. Moreover, it monitors thrust position with high precision. Secondly, the Bently Nevada 330876-01-90-01-05 reduces unplanned downtime. It provides real-time shaft displacement feedback. Additionally, its non-contact design avoids mechanical wear. You also benefit from high measurement repeatability. Besides, the probe resists oil and debris contamination. In turn, this lowers your overall maintenance costs. Consequently, your plant operates more safely and efficiently.
330876-01-90-01-05 Technical Insights
It contains a sealed tip coil. This coil generates a high-frequency magnetic field. Target distance changes the field impedance. The system then outputs a proportional voltage signal. Specifically, the scale factor is 7.87 V/mm. The linear measurement range starts at 0.25 mm. It ends at 1.25 mm from the target. Meanwhile, the probe body uses stainless steel. The connector type follows the standard 3300 NSv design. For best system performance, match this probe with a 330180-90-00 proximitor. Also, use the 330130-040-01 extension cable. Furthermore, avoid overtightening during installation. This simple step prevents internal coil damage.
