How Measuring Light Curtains Work

The light curtain includes an emitter, receiver, and supporting Shielded cable Same quantity of transmitting tubes and photoelectric tubes are built into the emitter and receiver respectively, the luminescent device in the transmitting tube and the light receiving device work simultaneously and check whether the light path is break-over. When the light path is blocked, there will be a detecting output from the system.

Fields of application for measuring light curtains

Measurement light curtain is widely used, covering almost all detection and measurement fields, such as precision correction, online correction, alignment correction, vehicle separation, object detection, shape measurement, small parts detection, object size detection, logistics sorting volume measurement, component counting, toll station vehicle detection, vehicle overrun inspection (length, width, and height), passage passenger flow Detection, object trajectory detection, human body detection, safety alarm, assembly line detection, automatic spraying, product counting detection, blanking counting detection, etc.
 

G-TEK's LSM（C） measurement light curtains are ideal for smart logistics industry measurement.In industries such as logistics, the measurement of product size and volume has always been a very common and necessary job. The measuring light curtain can automatically measure the tracking detection of objects on the packaging line and can detect and measure the volume and area of the packaging box online.

LSM（C） measurement light curtains provide a variety of advanced non-contact measurement methods to measure the shape, size, and contour of objects and also play a role in packaging measurement, area resolution, parts counting, sag control and skewness correction of coil materials. And widely used in logistics, transportation, machine tools, textile machinery, rubber machinery and other fields.

Five advantages of the product

1.No dead zone design 

The unique structural design makes the control area safe and without blind spots. To maximize the protection of the normal use of the product at the application site, avoid unnecessary accidents, and minimize the loss of customers in the work.

2. IP 65 Housing

While light grids at toll booths are housed in special enclosures to protect them from damage in case of vehicle collision, it is still important for the device itself to be reliable even in adverse environmental conditions.  Devices with IP 65 rated housing operate reliably even in dust or heavy rain.

3.Sunlight Immunity

LSM(C) is not only used in the indoor logistics industry, but also in outdoor application scenarios such as toll stations. Immunity to ambient light is a key factor when selecting optics for outdoor applications. Whether it is sunny or cloudy, the solution should be accurate and reliable, which is a strict requirement of G-TEK for LSM(C) measurement light curtains. The LSM(C) measurement light curtains with high ambient light immunity ensure consistent reliability under changing sunlight.

4. Multiple types of free choice

There are two installation methods available. Optical communication is flexible and convenient to install, and line communication solves the problem of interference when using multiple sets of gratings.LSM(C) offers 4 optical axis spacing options: 10mm/20mm/40mm/80mm.

5. Fast Response Time

Fast response time ensures accurate measurement of moving vehicles.  A reliable tolling system depends on light grids that will not miss a vehicle or mistake a truck driving through the tollway too quickly for a car.
