DISCOM engineering heritage and German acoustic testing benchmarks

German instrumentation specialist Discom Elektronische Systeme und Komponenten GmbH has engineered advanced acoustic quality analysis and vibration testing platforms since 1985.

Operating from the university town of Göttingen, the enterprise brings together experienced physicists and specialized engineers dedicated to production line quality assurance.

Discom platforms are deployed across major automotive assembly lines worldwide, providing continuous inspection of transmissions, gear units, e-drive systems, and engines at the end of the manufacturing line.

Over one hundred thousand transmissions are evaluated daily using Discom instrumentation, confirming outstanding technical reliability.

BKS03, BKS10 and BKS30 structure-borne vibration sensors for EOL rigs

The BKS accelerometer family comprises purpose-built structure-borne vibration sensors engineered for demanding automated test rig environments.

The sensing element contacts the metallic component surface through a durable elastomeric silicone damper, delivering reproducible acoustic coupling without distorting critical vibration signals.

This direct-coupling principle excludes surrounding shop floor acoustic noise, enabling precise identification of gear mesh anomalies and bearing flaws during early inspection stages.

Sensors are available in triaxial BKS03 and BKS10 versions, as well as BKS30 and BKS33 configurations with BNC connectors for integration into automated test bench actuators.

TAC15 rotational acceleration sensors and MVS18 magnetic transducers

To monitor rotational dynamics directly on moving drive shafts, Discom engineered the high-precision TAC15 torsional acceleration sensor.

Mounted adjacent to the rotating shaft on the test rig, the unit registers subtle angular fluctuations and torsional irregularities, transmitting high-resolution data to the TAS frontend via an optical link.

For evaluating development prototypes, complex assemblies, and specialized trial runs, the MVS18 magnetic vibration transducer utilizes a sensitive IEPE element.

A high-strength neodymium magnet ensures instantaneous attachment to ferrous surfaces, while a flexible silicone handle acts as a strain relief damper protecting against mechanical wiring disturbances.

DRM58 protected microphones and NFM contactless acoustic probes

The DRM58 industrial microphone is constructed to withstand aggressive factory environments while delivering acoustic quality analysis.

Built around a precision Brüel & Kjær Type 4958 capsule inside a solid metal housing with external M27 and internal M8 threads, the unit resists lubricating fluid spray and mechanical shop impacts.

When direct surface contact is impractical due to complex geometries or rounded profiles, the NFM near field microphone performs contactless inspection.

Tuned for frequencies from 300 hertz to 17 kilohertz with maximum ambient noise rejection up to 3 kilohertz, the sensor ensures high accuracy during assembly defect detection.

TAS28, TAS48 multi-channel frontends and TASnano mobile hardware

The hardware core of Discom systems centers on industrial TAS28 and TAS48 frontends that collect and condition signals from vibration transducers, microphones, and pulse encoders.

Each channel features a dedicated 24-bit analog-to-digital converter operating at rates up to 200 kilohertz, streaming digitized information to the host computer via USB.

For mobile vehicle trials and correlating test bench measurements with in-cabin acoustic conditions on the road, Discom provides the compact 4-channel TASnano module.

Built with smartphone dimensions, the unit draws power directly from a connected tablet or laptop USB port, supporting simultaneous recording across four ICP channels.

TasAlyser software platform and DISCOM component selection standards

Real-time data processing is executed by the flagship TasAlyser application within the Discom Software Suite.

Algorithms track rotational order spectra and frequency profiles in real time, comparing dynamic vibration signatures against defined tolerance templates and generating plain-text notifications when anomalies occur.

To maintain uninterrupted test rig uptime, a comprehensive catalog of replacement parts is available, including sensing heads, protective silicone tips, shielded coaxial cables, and bus interface modules.

Selection of compatible hardware is verified using the test rig serial number and nameplate details.
