Bently Nevada 330400-02-CN Accelerometer

Description

The 330400-02-CN is an accelerometer from the Bently Nevada 3300 series, configured with an M8 x 1 integral mounting stud (Option 02) and an integrated China hazardous area approval package (-CN). This transducer is designed for critical machinery applications requiring reliable casing acceleration measurements, such as gear mesh monitoring and overall machine protection. The 330400 model provides a sensitivity of 100 mV/g and an amplitude range of 50 g peak, ensuring consistent data acquisition for vibration analysis in industrial environments.

This accelerometer features a 316L stainless steel housing with a hermetically sealed case, making it suitable for demanding conditions. It utilizes a 3-pin MIL-C-5015 connector interface and maintains stable performance across a wide operating temperature range of -55 degC to +121 degC. Proper installation on the machine bearing housing or casing is essential to maintain specified frequency response and amplitude accuracy, as outlined in the manufacturer guidelines.

Installation Guidelines

Ensure the accelerometer is installed on a clean, flat surface on the bearing housing or machine casing to maintain optimal signal transmission. Use the recommended mounting torque of 4.1 N-m (3.0 ft-lb). For installations in hazardous areas, adhere to local regulations and the specific entity parameters provided in the Bently Nevada documentation. Use appropriate shielded cables and ensure the mating connector is properly secured to maintain IP rating integrity.
