SW9113 ATEX Vibration Test System - RMS

Product Description

The SW9113 ATEX from RMS is, in the manufacturer’s words, the only electrodynamic vibration test system in the world that can be operated safely in potentially explosive atmospheres. It brings the proven performance of the RMS SW9100 series into hazardous (Ex) areas, where conventional shakers cannot be used.

The oscillating systems meet the current EU Directive 2014/34/EU (ATEX) and are TUV-certified, drawing on more than ten years of RMS experience with ATEX-compliant test technology. This lets laboratories perform explosive tests, resonance determination, and ageing and strength tests on sensors and complete assemblies - such as injection systems, fuel pumps and batteries - in the very environments those products are built to withstand.

Key Features

  • Built for safe operation in potentially explosive (Ex) atmospheres - ATEX per EU Directive 2014/34/EU, TUV-certified
  • Up to 80 kN sine and random force, up to 160 kN shock force
  • Usable frequency range of 5 - 2500 Hz
  • Shock capability of 3.5 m/s for 100g / 11 ms shocks, with full-power precision down to 0.1g
  • Water cooling system (57 dBA) with an ECO mode for energy savings
  • Wear-free return spring system with high transverse rigidity despite 76 mm pk-pk travel
  • RMS guide elements reduce lateral acceleration
  • Fully automatic centre positioning
  • Modular, compact design with multiple expansion stages
  • Complies with EnEV2016 and ISO 14001

Designed for demanding qualification work in hazardous environments, the SW9113 ATEX combines high force, precise control and energy-efficient water cooling so that explosive, durability and resonance testing can be carried out safely and repeatably.

Frequently Asked Questions

What makes the SW9113 ATEX suitable for explosive atmospheres?
The SW9113 ATEX is described by RMS as the only electrodynamic vibration test system in the world that can be operated safely in potentially explosive atmospheres. Its oscillating systems meet the current EU Directive 2014/34/EU (ATEX) and are TUV-certified, building on more than ten years of RMS ATEX experience.
What force levels can the SW9113 ATEX deliver?
Based on the SW9100 series platform, the system provides up to 80 kN of sine and random force and up to 160 kN of shock force, with a shock capability of 3.5 m/s for 100g / 11 ms shocks - enough to test heavy specimens and complete assemblies.
What is the frequency range and travel of the system?
The usable frequency range is 5 - 2500 Hz with an armature resonance of 2300 Hz. The wear-free return spring system maintains high transverse rigidity despite a travel amplitude of 76 mm peak-to-peak in shock mode (51 mm pk-pk in sine).
How is the SW9113 ATEX cooled and how quiet is it?
The system uses a water cooling system, which is more energy-efficient, space-saving and quieter than air cooling, with the cooling system rated at 57 dBA and the amplifier system at 65 dBA. An ECO mode provides further energy savings.
What applications is the SW9113 ATEX used for?
Typical applications include explosive tests, resonance determination, and ageing and strength tests of sensors and complete assemblies - for example injection systems, fuel pumps and batteries that must be qualified for use in or near explosive environments.
Does the system support precise low-level and automated testing?
Yes. It offers full-power precision down to 0.1g, fully automatic centre positioning, and RMS guide elements that reduce lateral acceleration, supporting repeatable and accurate vibration and shock testing.
