Applications

Tips: Briefly introduce the working principle of laser tachometer

A laser tachometer is a non-contact device used to measure the rotational speed (RPM) of a surface or object. Its working principle involves the following key steps:

Laser Emission: The tachometer emits a coherent laser beam towards the rotating object.
Reflection: When the laser beam strikes the surface of the object, it reflects to the tachometer. The surface of the object should ideally be rough or have a reflective marking to enhance the reflection.
Detection: The tachometer contains a photodetector that senses the reflected laser beam.
Frequency Measurement: As the object rotates, the laser beam hits different points on the surface. The tachometer measures the time interval between successive reflections, which is related to the speed of rotation.
Output Calculation: The device calculates the rotational speed in RPM based on the frequency of the reflected signals and displays the result.

Laser tachometers are valued for their accuracy, non-contact measurement, and ability to work with a variety of surfaces and speeds, making them ideal for many industrial applications.

Builder in Product TAB

NEW! Since Journal 3.2, the much improved T.A.B (Tabs Accordion Blocks) system supports the page builder inside the tab content. Unlimited Blocks, Tabs or Accordions with any HTML content or the builder interface (supporting custom rows/columns/modules) can be assigned to any individual product or to certain groups of products, like entire categories, brands, products with specific options, attributes, price range, etc. You can indicate any criteria via the advanced product assignment mechanism and only those products matching your criteria will display the modules. Also, any module can be selectively activated per device (desktop/tablet/phone), customer login status and other criteria. Imagine the possibilities.
