BENTLY 163179-02 Accelerometer

Overview

The 163179-02 accelerometer utilizes advanced piezoelectric sensing technology to convert mechanical vibration into an electrical signal proportional to acceleration. It features a rugged, hermetically sealed stainless steel housing suitable for harsh industrial environments. The sensor incorporates internal electronics that condition the signal and provide a low-impedance voltage output, making it compatible with standard IEPE (Integrated Electronics Piezoelectric) inputs on monitors and data collectors.

Key Features

• Wide Frequency Range: Capable of measuring vibration from 0.5 Hz to 10 kHz, covering most machinery fault frequencies.

• High Sensitivity: Typically 100 mV/g, providing excellent signal-to-noise ratio.

• Rugged Construction: Stainless steel body, hermetic seal, and integral cable options for durability.

• IEPE Compatibility: Operates from constant current power (2-10 mA) and outputs a low-impedance voltage signal.

• Wide Temperature Range: -50°C to +120°C, suitable for most industrial applications.

• Isolated Base: Electrically isolated from the mounting surface to prevent ground loops.

• Approvals: CSA, ATEX, and IECEx for hazardous area installations when used with appropriate barriers.

Technical Specifications

• Sensitivity: 100 mV/g ±5% @ 100 Hz.
