Overview

The Bently Nevada 100A1000 (also referred to as the 100A1000/01) is a highly sensitive acceleration transducer designed for machinery condition monitoring and protection. Its primary role is to detect early signs of mechanical issues such as bearing failures or gear mesh problems by capturing high-frequency vibration signals. Ideal for use in demanding industrial settings, this accelerometer is known for its precision and durability.

Key Features

• High Sensitivity: With a sensitivity of 100 mV/g (10.2 mV/m/s²), the 100A1000 is capable of detecting even minute vibrations, providing early warnings of equipment failure.

• Broad Frequency Range: The accelerometer operates across a wide frequency spectrum, from 0.5 Hz to 10,000 Hz (± 3dB), making it suitable for monitoring both low-speed machinery and high-speed gear vibrations.

• Wide Operating Temperature Range: It functions reliably in extreme environments with temperatures ranging from -54°C to +121°C (-65°F to +250°F), making it ideal for harsh industrial conditions.

• Rugged Construction: Built from 316L stainless steel, the 100A1000 is corrosion-resistant and robust enough to withstand demanding conditions found in power plants, refineries, and other industrial applications.

• Vibration Protection: Featuring hermetically sealed construction, the sensor is resistant to moisture and environmental contaminants, ensuring reliable operation even in wet or humid environments.

• Electromagnetic Interference (EMI) Shielding: Internal shielding reduces susceptibility to electrical noise from nearby machinery, such as motors and cables, ensuring accurate signal transmission.

• Versatile Mounting Options: The accelerometer comes with a 1/4-28 UNF mounting hole, enabling flexible installation options, including stud mounting or adhesive pad attachment.
