Description

Parameter	Details
Model	330980-71-05
Manufacturer	Bently Nevada
Product Type	Eddy – Current Proximity Sensor
Series	3300 XL NSv
Measurement Range	Typically up to 12.7 mm (0.5 inches)
Accuracy	Typically ± 0.1% of full scale
Resolution	Typically 0.0025 mm (0.0001 inches)
Output Signal	Voltage or current proportional to the target distance
Target Material	Ferrous metals (e.g., iron, steel)
Operating Temperature Range	– 40 °C to + 121 °C (- 40 °F to 250 °F)
Storage Temperature Range	– 51 °C to + 105 °C (- 60 °F to + 221 °F)
Mounting	Threaded stud or flange mount
Proximitor Sensor Material	A380 aluminum
Proximitor Sensor Input	Accepts one non – contacting 3300 RAM or 3300 NSv proximity probe and extension cable
Power	Requires – 17.5 VDC to – 26 VDC without barriers at 12 mA maximum consumption; – 23 VDC to – 26 VDC with barriers. Operation at a more positive voltage than – 23.5 VDC can result in reduced linear range
Dimensions	Not provided in a standard form in the given sources. However, for a reference related to its mounting, it can be installed in a high – density DIN – rail or traditional panel – mount configuration. If DIN – rail mount, it likely has a form factor suitable for standard DIN – rail dimensions (around 35 mm width for standard DIN – rails). In a traditional panel – mount, it shares an identical 4 – hole mounting “footprint” with older proximitor sensor designs, but exact size details are not given.
Weight	0.5 kg
Applications	Ideal for centrifugal air compressors, refrigeration compressors, process gas compressors, and other machines with tight installation requirements. Also suitable for small – target applications such as measuring radial vibration on shafts smaller than 51 mm (2 in) or axial position on flat targets smaller than 15 mm (0.6 in)
Immunity	Highly immune to radio frequency interference, allowing installation in fiberglass housings without adverse effects from nearby radio frequency signals. Its improved RFI/EMI immunity satisfies European CE mark approvals without requiring special shielded conduit or metallic housings

About brand

The BENTLY 3500 system is a professional machinery protection and condition monitoring solution widely used in industries like oil and gas, power generation, and petrochemicals. It adopts a modular design, allowing flexible configuration of monitoring modules (e.g., vibration, temperature, and speed modules) to track key operating parameters of rotating equipment such as turbines and compressors. By collecting and analyzing data in real time, it can promptly identify issues like equipment imbalance or bearing wear, trigger alarms or shutdowns when thresholds are exceeded, and effectively prevent unexpected equipment failures to ensure production continuity.
