High-end sensor for the test bench

Structure-borne Sound Sensor

Most successful sensor for end-of-line

The best and most successful sensor worldwide for end-of-line testing in manufacturing companies in the automotive industry and their suppliers: Discom structure-borne sound sensors BKS03 and BKS10 measure vibrations directly on the test object – which makes them independent of the noise level in production.

Reproducibility of measurements

BKS sensors are developed for the requirements of end-of-line testing of e-drive systems and its components such as transmissions and e-motors. These accelerometers are generally automatically pressed onto the test specimen in the end-of-line test. The Discom solution is at today’s state of the art technology and thus replaces earlier spring-loaded sensors. Outdated spring-loaded sensors do not gernerate precise measured values or guarantee reliable reproducibility of measurements and there is barely any correlation between measured values of permanently mounted vs spring-loaded sensors. On the other hand, modern Discom sensors provide reliable and reproducible measurement accuracy. BKS sensors provide manufacturing companies with state of the art measurement technology and provide exact measured values that can be used to safeguard and improve the company’s manufacturing quality.

Excellent measurement results

This is where Discom BKS sensors show their strengths: The light sensors with optimized contact surfaces are pressed onto the test specimen with an elastic silicone body. The measurement results they provide are just as reliable and high-precision as screwed sensors. The low weight of the sensors offers an additional advantage: They are ideal for quality control of smaller test specimens. Of course the necessary cycle times in the second range are possible.

For harsh industrial applications

At the same time, BKS sensors are also optimized for harsh industrial applications: The silicone bodies are not subject to any wear and thus guarantee a long operating lifetime. The sensors are electrically insulated and suitable for a wide temperature range.

Standard in the automotive industry

Due to these enormous advantages, Discom BKS sensors have become the standard for many automobile manufacturers.

BKS30 – general purpose vibration sensor with a BNC socket

BKS30

General purpose vibration sensor with a BNC socket

BKS30 is part of Discom’s latest sensor generation, developed for structure-borne vibration acquisition in EoL (End-of-Line) testing environments. It enables accurate, reliable, and real-time signal acquisition during production testing of e-drives and transmissions.

The BKS30 allows the use of robust plugs and cables directly at the base of the sensor assembly which makes it easy to service as an individual exchange of the cable or sensor is possible. The sensor is screwed directly into the elastic element and allows an improved IP rating for the whole sensor assembly.

BKS30: Specifications

Sensitivity:
10 mV/g or 25 mV/g

Frequency range:
up to 40 kHz, linear up to 14 kHz

Dimensions:
diameter 34 mm and length 108 mm with the BNC socket

IEPE:
Compatible with all measurement systems with IEPE (ICP®, CCLD®) input

BKS33 preload detection

BKS33 – preload detection

BKS33 – preload detection is part of Discom’s latest sensor generation and adds a force indication system to the Discom structure borne vibration sensors. This system indicates whether the optimal amount of force is applied, enabling easy sensor setup and continuous monitoring throughout the test cycle.

The integrated pre-load indicator enables adjustment of optimal working conditions with max. frequency range and sensitivity.

BKS33: Specifications

Sensitivity:
10 mV/g or 25 mV/g

Frequency range:
up to 40 kHz, linear to 14 kHz

Dimensions:
diameter 34 mm and length 97 mm

IEPE:
Compatible with all measurement systems with IEPE (ICP®, CCLD®) input

BKS10 compact sensor

BKS10

Compact sensor for limited installation spaces

The BKS10 has the same basic properties as the BKS03, except that the shape of the silicone spring element has been adapted to meet the new requirements for compact design. Special sensors are used which enable protected cable routing within the spring element. With a mounting adapter, BKS03 sensors can be exchanged 1:1. This enables fast refits of existing assembly lines for new requirements.

BKS10: Specifications

Sensitivity:
10 mV/g or 25 mV/g

Frequency range:
up to 40 kHz, linear to 14 kHz

Dimensions:
diameter 18 mm and length 65 mm

Optimal for limited installation spaces:
small diameter

IEPE:
Compatible with all measurement systems with IEPE (ICP®, CCLD®) input

BKS23 general purpose vibration sensor

BKS23

General purpose vibration sensor with a wide range of application

BKS23 is designed to meet the demands of modern production lines. It combines the advantages of the previous BKS03 Discom sensor like flexible mounting, consistent performance, robust design and stability due to the spherical silicone spring element. BKS23 features improved cable guidance for easier application in the test environment and better durability of the sensor cables.
