Bently Nevada AM3100T2-Z2 Case Mounted Accelerometer 100 mV/g

Bently Nevada AM3100T2-Z2 Case Mounted Accelerometer – Reliable Vibration Sensing

Product Introduction

This AM3100T2-Z2 accelerometer from Bently Nevada captures vibration signals on case-mounted equipment. Many plants use it for compressors, pumps, and turbines. Its robust design ensures stable readings under harsh conditions.

Key Dynamic Specifications

The AM3100T2-Z2 offers a sensitivity of 100 mV/g ±5% at 25°C. Its acceleration range reaches 80 g peak, with amplitude nonlinearity limited to 1%.

Frequency response stays within ±10% from 0.7 to 9,000 Hz. For wider needs, the ±3 dB range covers 0.4 to 14,000 Hz. The resonant frequency is 30 kHz, well above typical machine vibration bands.

Transverse sensitivity is kept at a maximum of ±5% of axial sensitivity. Temperature response shows -20% at -55°C and +10% at +120°C. Therefore, this sensor works reliably across extreme environments.

Mechanical and Environmental Features

This case mounted accelerometer uses a stainless steel housing. It withstands high humidity and oil exposure. The mounting stud pattern fits standard 1/4-28 UNF threads.

Furthermore, the device operates from -55°C to +120°C. It resists dust and water ingress per IP67 rating. Meanwhile, the cable exit is side-exit for tight spaces.

Installation Guidelines

First, clean the mounting surface thoroughly before installation. Apply a thin layer of coupling grease to the stud. Then torque the AM3100T2-Z2 to 5–7 N·m.

For temporary mounting, use a magnetic base adapter. However, permanent stud mounting provides the best high-frequency response. Avoid overtightening, which may damage the internal crystal.

Specifically, route the cable away from high-temperature sources. Secure the cable with soft ties to prevent vibration fatigue. Finally, verify the output with a handheld vibration meter before commissioning.

Why Choose This Replacement Model

This unit directly replaces older AM3100T2-Z2 variants. It maintains identical mounting and electrical interfaces. Consequently, you can swap it without modifying existing wiring.

Additionally, Bently Nevada applies strict quality control. Each sensor is tested before shipment. You receive a factory-sealed unit with a full 12-month warranty.

Frequently Asked Questions (FAQ)

1. Can I use the AM3100T2-Z2 in a high-temperature environment above 100°C?
Yes, this sensor operates up to 120°C. However, the temperature response adds +10% at that limit. Therefore, you may need to adjust gain in your monitoring system.

2. Is this AM3100T2-Z2 a direct replacement for my older Bently Nevada sensor?
Yes. This model is specifically listed as a replacement for previous AM3100T2-Z2 versions. Mounting thread and output sensitivity remain identical.

3. What is the maximum cable length I can use with this accelerometer?
You can extend the cable up to 300 meters without significant signal loss. For best results above 100 meters, use a low-noise coaxial cable.

4. Do I need to order a separate power supply for this sensor?
No. The AM3100T2-Z2 is a passive piezoelectric accelerometer. It requires no external power. Just connect it to a vibration monitor with an IEPE compatible input.

5. What shipping methods are available for international orders?
We ship via FedEx, UPS, and DHL worldwide. Delivery typically takes 3 to 7 business days depending on your location.
