FREE Shipping by … Keep reading to learn more about how they work, and decide if they’re right for your application. These sensors can provide point level measurement, the light source and detector are shielded from each other and they are mounted in an enclosed housing as shown in the above image. There are a range of technical terms used to describe this type of level sensing technology. Continuous optical level sensors, on the other hand, use the highly intense laser light that can infuse dusty environments and notice liquid substances. Automatic Level 32X Optical Transit Survey Auto Level High Precision Level Gauge Measure Meter Machine. In addition, optical level sensors are unsuited for applications where top mounting is necessary; when top-mounted, the accuracy optical level sensors may be adversely affected by moisture condensation. With no moving parts, these small units are ideal for a variety of point level sensing applications — especially where dependability and economy are a must. Optical sensors work by converting light rays into electrical signals which measure a physical quantity of light then translate it into a measurement. What is a variable displacement level device and how does it measure the level? Inside the sensor housing is an LED and a phototransistor. If you think an optical level sensor is right for your application, consider one of these two models from SMD Fluid Controls. Thanks to this, the sensor con-struction is simple, robust and reliable. We can use laser light insted of infrared and the advantage of the laser light is that it is more concentrated so it could penetrate dust or steam and the laser light will be reflected from most solids and liquid surfaces.
