Product Introduction
The Bently Nevada 330905-00-25-05-02-05 is a 3300 NSv (Narrow Side View) proximity probe specifically engineered for applications requiring close-range shaft vibration and position monitoring where space constraints limit probe installation. Designed for use in conjunction with compatible NSv extension cables and drivers, this 0.5-meter proximity probe offers reliable, high-precision measurement of shaft dynamic motion, making it particularly suited for small or tight clearances in machines like gearboxes, small turbines, or compact rotating equipment.
The 330905 series leverages non-contact eddy current sensing technology to detect conductive surface displacement, offering non-intrusive, continuous monitoring without physical contact. Its rugged stainless-steel construction, shielded cabling, and compliance with API 670 standards ensure exceptional performance in industrial environments such as oil and gas, petrochemicals, and power generation. With a shipping weight of 2 kg, the product is robust and carefully packaged to prevent transport damage.
