We at Datum Electronics have been working to create highly accurate cost-effective torque sensing solutions and developed an M425 Series rotating torque sensor, to fulfill your shaft power measurement needs.
To many German companies Industry 4.0 means: We change our production facilities, turn our factory into a Smart Factory, and are fully committed to digitization and automation. An integral part of it: Smart robots that by now can do much more than just move parts from A to B. But the machines are not only getting smarter, they are also supposed to work faster and more efficiently - while being robust, resilient and as maintenance-free as possible. Every technical failure leads to expensive downtimes and slows down production. Our sensors help you to avoid such failures and optimize your robots.
In the episode 1, we have got a overview about inverse magnetostrictive torque sensors. In this episode, we are going to learn more about NCTE sensors and their advatages.
This application note describes methods, technical challenges and the INFICON solution for leak testing of Glove Boxes, RABS (Restricted Access Barrier System), Isolators, MSC (Microbiological Safety Cabinets) and BSC (Bacteria Safety Cabinets).
The NCTE technology works completely contactless. We use the principle of magnetostriction, which works without maintenance and wear. Our sensors detect in real time whether a wind turbine is wearing out and provide all necessary data for optimized maintenance cycles. Rough external conditions do not matter. Our sensors work precisely and flawlessly even in high humidity, salty sea air and fluctuating temperatures.
The active element of an accelerometer is a piezoelectric material. Figure 1 illustrates the piezoelectric effect with the help of a compression disk. A compression disk looks like a capacitor with the piezoceramic material sandwiched between two electrodes. A force applied perpendicular to the disk causes a charge production and a voltage at the electrodes.
For decades the applications of sensors measuring torque and force changed rather little. In recent years new challenges arose which require new innovative solutions for sensors and large volumes in sensor production. Conventional torque sensors on the basis of strain gauges are still very useful for very precise measurements in test applications, for instance. However, they are very expensive and also their maintenance is very costly. This prevents their use in large numbers and they are therefore not suitable for the new requirements. Apart from this the conventional technical solutions are not suitable for applications in industry 4.0, big data and serial smart products. There is a new technology that offers a solution to this issue which is suitable for serial production: non-contact torque sensors based on magnetostriction.
Under normal conditions, piezoelectric sensors are extremely stable and their calibrated performance characteristics do not change over time. However, often sensors are exposed to harsh environmental conditions, like mechanical shock, temperature changes, humidity etc. Therefore it is recommended to establish a recalibration cycle. For applications where high accuracy is required, we recommend to recalibrate the accelerometer every time after use under severe conditions or at least every 2 years. In some less critical applications, for example in machine monitoring, recalibration may be unnecessary.
