The 330450-80-00 is a Bently Nevada high-temperature acceleration system with an 8 m integral hardline cable. It separates the sensing head from the signal-conditioning electronics so the electronics can be installed in a cooler location.
- High-temperature sensing head with remotely located signal-conditioning electronics
- 10.2 mV/m/s² (100 mV/g) sensitivity ±5%
- 785 m/s² (80 g) peak overall acceleration range
- Hermetically sealed 3-pin MIL-C-5015 connector
The 330450 High Temperature Acceleration System is intended for casing or bearing-housing vibration measurements on rotating equipment operating in elevated-temperature environments. The sensing head, integral hardline cable, and electronics form a matched system. For dependable measurement, install the sensing head on a properly prepared machine surface and follow the official mounting, wiring, bend-radius, environmental, and safety instructions.
Important Notice: Mounting hardware, interconnect cables, manuals, calibration data, software, and other accessories are not included unless specifically listed in the quotation or stock description.
Bently Nevada 330450-80-00 Manuals and Datasheets
Important Notice: Document revisions and product specifications may change. Confirm that the document revision and nameplate configuration match the unit being quoted before installation or replacement.
Gas and Steam Turbines
Measures casing or bearing-housing acceleration in elevated-temperature areas where conventional integrated-electronics accelerometers may not be suitable.
Compressors
Supports vibration monitoring on process, pipeline, refrigeration, and gas-compression machinery with hot bearing housings or casings.
Pumps and Fans
Provides casing vibration measurements for boiler-feed pumps, induced-draft fans, forced-draft fans, and other rotating auxiliary equipment.
Power Generation
Used in machinery protection and condition-monitoring programs for critical rotating assets in thermal, combined-cycle, and industrial power facilities.
Oil, Gas, and Process Industries
Supports high-temperature machinery monitoring in refineries, petrochemical plants, LNG facilities, and other continuous-process environments. Confirm the exact hazardous-area approval from the product nameplate before use.
Read and follow the official 330450 user guide before installation or use. Mount the sensing head on a clean, flat, properly prepared bearing housing or machine casing so the measured vibration is transmitted accurately.
- Do not bend the integral hardline cable below the published minimum bend radius of 51 mm (2.0 in).
- Use the specified -24 ± 0.5 Vdc supply and verify polarity, grounding, connector, and monitor compatibility before energizing the system.
- Keep the signal-conditioning electronics within their published temperature limits and verify the sensing-head limit for the exact serial-number version.
- Do not assume hazardous-area approval from the part number alone; confirm certification and installation drawing requirements from the nameplate and current documentation.
- Confirm mounting hardware, interconnect cable, accessories, calibration requirements, and required documentation before placing the order.
