German TROLEX sensors TROLEX models TROLEX prices

TROLEX sensors are devices that convert mass signals into measurable electrical signal outputs. When using sensors, the actual working environment of the sensor should be considered first; this is crucial for the correct selection of load cells, as it affects whether the sensor can operate normally, its safety and service life, and even the reliability and safety of the entire weighing apparatus. There are qualitative differences between the old and new national standards regarding the basic concepts and evaluation methods of the main technical indicators of load cells. The main types include S type, cantilever type, spoke type, plate ring type, capsule type, bridge type, and column cylinder type.

TROLEX sensor basic principles

Vision sensors have thousands of pixels that capture light from an entire image. The clarity and fineness of an image are usually measured by resolution, expressed in pixel count. Some vision sensors provided by Banner Engineering Company can capture 130 ten thousand pixels. Therefore, regardless of whether the target is meters or centimeters away, the sensor can "see" a very detailed target image. After capturing the image, the vision sensor compares it with reference images stored in memory to perform analysis. For example, if a vision sensor is set to identify machine parts with eight correctly inserted bolts, the sensor knows to reject parts with only seven bolts or misaligned bolts. In addition, regardless of where the machine part is located in the field of view, and regardless of whether the part rotates within a 360 degree range, the vision sensor can make a judgment.

TROLEX sensor application fields

The low cost and ease of use of vision sensors have attracted machine designers and process engineers to integrate them into various applications that previously relied on manual labor, multiple photoelectric sensors, or no inspection at all. Industrial applications of vision sensors include inspection, metrology, measurement, orientation, defect detection, and sorting. The following are just some application examples: In automobile assembly plants, inspecting whether the glue beads applied by robots to door frames are continuous and have the correct width. In bottling plants, verifying whether bottle caps are correctly sealed, whether the filling level is correct, and that no foreign matter falls into the bottles before capping. On packaging production lines, ensuring that the correct packaging labels are affixed in the correct positions. On pharmaceutical packaging production lines, inspecting blister packs of aspirin tablets for broken or missing tablets. In metal stamping companies, inspecting stamped parts at a rate of over 150 pieces per minute, which is more than 13 times faster than manual inspection.

TROLEX sensor classification

Photosensitive sensors are one of the most common types of vision sensors. They come in many varieties, mainly including: phototubes, photomultiplier tubes, photoresistors, phototransistors, solar cells, infrared sensors, ultraviolet sensors, fiber-optic photoelectric sensors, color sensors, CCD, and CMOS image sensors. Light sensors are among the most produced and widely used sensors, playing a very important role in automatic control and non-electrical electrical measurement technology. The simplest photosensitive sensor is the photoresistor, which generates current when photons strike the junction. Sensors should be packaged in anti-static bags. During use, avoid using them in humid environments, and pay attention to surface damage and contamination levels, as these will affect the photocurrent.
