682G88 Industrial Accelerometer (High-Frequency IEPE Type)

The 682G88 series is a heavy-duty industrial accelerometer engineered to deliver precise, continuous vibration monitoring and dynamic shock measurements on high-speed factory machinery. Equipped with internal IEPE (Integrated Electronics Piezo-Electric) circuitry, this low-impedance sensor conditions raw acceleration events on-board, allowing for stable, noise-free voltage transmission over long cable distances without signal loss. Built to survive harsh manufacturing environments, the 682G88 pairs a robust ±500g dynamic range with a high resonant frequency ≥48 KHz making it an essential diagnostics tool for industrial turbines, high-speed spindles, and predictive maintenance programs.

 

Key Features

• • On-Board IEPE Low-Impedance Electronics: Features an integrated internal amplifier network that delivers a stable 10 mV/g voltage signal, effectively suppressing triboelectric line noise and environmental electromagnetic interference (EMI) on the factory floor.

  • High-G Dynamic Shock & Vibration Survival: Built to withstand severe structural stress profiles, with continuous sinusoidal vibration limits up to 2200g and sudden mechanical shock limits up to 5500g  without calibration shifts.

  • Broad Linear Frequency Flattening: Achieves an exceptional mounted natural resonant frequency ≥48kHz to prevent sensor-induced phase errors, ensuring excellent linearity from 2 to 10,000 Hz (±5%) and 1.2 to 12,000 Hz (±10%).

  • Welded Stainless Steel Shielding: Encapsulated in a ruggedized, hermetically sealed stainless steel housing equipped with a standard M5 threaded interface to guarantee zero fluid ingress and long-term chemical resistance.

FAQ

Q1: What are the primary benefits of using an IEPE industrial accelerometer like the 682G88 over traditional charge-mode sensors?

A: The 682G88 features integrated electronics (IEPE) that convert high-impedance charge into a low-impedance voltage output directly inside the sensor. This eliminates the need for expensive external charge amplifiers and allows the signal to travel over long coaxial cables without data degradation or interference from factory floor EMI.

Q2: Can the 682G88 industrial accelerometer be used for high-speed spindle and machine tool monitoring?

A: Yes. With a wide frequency response extending up to 12 kHz (±10%) and a high resonant frequency ≥48, the 682G88 is perfectly optimized for capturing high-frequency harmonics, bearing faults, and gear mesh vibrations common in high-speed CNC spindles and gearboxes.
