Vibration sensor for monitoring the machine vibration

February 23.02.2021, XNUMX | Vibration monitoring in applications such as papermaking and paper converting machines requires continuous vibration measurement. With the vibration sensor from PCB piezotronics the operational safety of the machines can be increased and production efficiency increased.

To implement necessary maintenance work proactively and cost-effectively is the point of condition monitoring and Predictive Maintenance. One measure against this background is vibration monitoring. Especially Rolling are hard-stressed components in rotating production machines.

The damage or the total failure of these components impair the quality of the product and cause additional costs. The Storage locations are located in hot, wet or other hazardous areas that are only partially accessible to maintenance personnel and service technicians. This can be easily adapted with well thought-out instrumentation for vibration monitoring.

The vibration sensors from PCB Piezotronics are welded in a double-walled, hermetically sealed manner stainless steel case installed. This protects against environmental influences and pollution. The housing also acts as a Faraday cage that prevents electrical interference. The galvanic separation of the sensor element and the subsequent measuring chain from the housing of the Sensors prevents ground loops and noise.

Sensors for measuring low accelerations

October 29.10.2019, XNUMX | The acceleration sensors from Micro-Epsilon were developed for industrial requirements. The inertial sensor from the ACC series (picture above) measures even low accelerations precisely and reliably. From the acceleration measurement in mobile machines Values ​​are recorded precisely, right up to the ground vibration of measuring and calibration systems.

Two models have been developed for industrial requirements. Thanks to its high Signal-to-noise ratioThe ACC5703 inertial sensor also detects low accelerations such as floor vibrations from measuring and calibration systems or manufacturingrobotics. He can for them condition monitoring be used in electrical machines, as the robust aluminum die-cast housing of the acceleration sensor ensures high EMC resistance.

Acceleration is recorded by the sensor in three axes and simultaneously with high resolution and accuracy. The measuring range can be continuously adjusted between ±100 mg and up to ±8 g. The combination of high temperature stability, EMC strength and precision is in, for example Wind Turbines required when generator oscillations are monitored.

The compact acceleration sensor offers high shock resistance, high IP protection and can be quickly installed via the AMP connector. The sensor is used primarily in mobile machines to precisely detect critical accelerations and vibrations.

Acceleration sensors make external measurement data acquisition unnecessary

13.05.2019 | ASC presents digital sensors from the new Disens product line. The ASC Disens MD-002 and MD-008 acceleration sensor types record measurement data with high accuracy. When using these triaxial sensors, external measurement data acquisition is no longer necessary, as the analog input signals are already converted into digital output signals in the sensor.

The sensors work with the measuring ranges ±2g and ±8g and enable highly precise measurements due to a low noise density of just 25 µg/Hz. Both sensors are particularly suitable for monitoring seismic activity as well as bridge and building monitoring.

The ASC Disens MD-002 / MD-008 include a full license for the extensive Software packet Dewesoft X3, which offers numerous simplifications for daily test and measurement work. The software offers a wide range of functions and saves test and measurement engineers a lot of time. In addition, the user can easily add new applications without having to invest in additional hardware. The software therefore meets all requirements: recording, analysis, reporting of measurement data. The learning effort required to familiarize yourself with the products is low.

Shock sensor for transport monitoring in intralogistics

Aspion shock sensors11.02.2019 | Aspion presents the newly developed shock sensor “G-Log 2” for transport monitoring and use in intralogistics. The event-controlled shock and climate data collection, long battery life and versatile communicationpossibilities of the Sensors are specially designed for the requirements in the area of ​​machine and plant export.

When developing the next generation of G-Log 2 shock sensors from Aspion, the engineers primarily focused on recording Humidity, BLE communication and the ability to change the battery yourself. The new G-Log 2 is equipped with a climate sensor for humidity and temperature and thus provides evidence of any corrosion damage.

The recording of shock, for example due to improper handling when handling goods, is based on the event principle. The G-log accelerates in three axes with up to each ± 24g recorded with directional information, which makes vibrations traceable at ms level.

With the evaluation data from data logger Transport damage that has occurred is verifiably shown to service providers, insurance companies and customers with the shock sensors - even in the case of damage caused by shock that is not recognizable at first glance. But also when used in the Intralogistik Aspion's G-log 2 detects unusual occurrences. In this way, conclusions about the causes are quickly transparent, even on the company premises or in the warehouse, and necessary measures can be taken.

The shock sensor from Aspion is with a combination of NFC / BLE wireless technology and thus enables versatile communication for the evaluations. The writing and commissioning of the sensor is carried out wirelessly using PC software via NFC, and the collected data can also be read out using a smartphone app using both NFC and BLE.

November 5.11.2012, XNUMX | Together with researchers from Fraunhofer-Institute for Integrated Circuits IIS in Erlangen, Lucht and her team have further developed Hopscotch Actisens, a Accelerometer from Fraunhofer IIS, supplemented. This records all movements, records their intensity and then evaluates them.

FAQ

What does an acceleration sensor do?

An accelerometer, also known as accelerometer or accelerometer, is a device that measures acceleration forces. These forces can be static, such as the force of gravity acting on an object, or dynamic, such as the forces that occur during movement, shock, or vibration. Acceleration sensors are able to record the direction and magnitude of acceleration.

Where are acceleration sensors used?

Acceleration sensors can be found in various applications: from automotive technology, where they are used in airbag systems, for example, to aerospace, to consumer electronics such as smartphones and fitness trackers. In smartphones, for example, they enable screen rotation and are used for pedometer applications.

How does the accelerometer work in the cell phone?

Accelerometers are used to measure the change in an object's speed with respect to time. Modern acceleration sensors often use microelectromechanical systems (MEMS), which are very small but still enable precise measurements.
