A laser particle size analyzer is an instrument that analyzes particle size by analyzing the spatial distribution (scattering spectrum) of diffracted or scattered light. Utilizing Furanhofer diffraction and Mie scattering theories, the testing process is unaffected by factors such as temperature changes, medium viscosity, sample density, and surface condition. As long as the sample is uniformly projected onto the laser beam, accurate test results can be obtained. Furthermore, as a novel particle size testing instrument, the laser particle size analyzer boasts outstanding features such as accuracy, reliability, high testing speed, good repeatability, and ease of operation. It integrates laser technology, computer technology, and optoelectronic technology, making it a new generation of particle size testing instruments that has been widely applied in powder processing, application, and research.
Laser particle size analyzers possess reliable circulating dispersion systems, such as wet circulating dispersion systems, including anti-dry-burn ultrasonic dispersers, centrifugal circulating pumps, automatic water inlet systems, and automatic drainage and overflow systems. Suitable for all samples, these systems ensure thorough sample dispersion, guaranteeing the accuracy and repeatability of the tests. Below, the ICbuy.com editor will briefly introduce how a photoelectric liquid level switch controls the automatic water intake of the laser particle size analyzer.
Automatic water suction technology is superior to automatic water intake technology because it pumps water from the bucket into the circulation tank, ensuring water quality and offering flexibility and convenience. The laser particle size analyzer is equipped with a water pump and a water level measuring device. The inlet valve controls the water intake through the inlet pipe (connected to a water source such as a tap), automatically drawing water from the bucket into the circulation tank, thus enabling automatic water intake during testing and rinsing.
For water level detection, the automatic water intake process is monitored. When the water level in the sample tank exceeds the limit set by the water level gauge, the inlet valve is immediately closed to stop water intake, and a full water level alarm signal is sent to the computer. If the UK SST photoelectric level sensor/photoelectric level switch – LLC200D3SH – provided by ICbuy.com is installed in the level detection device, the alarm system will be even more comprehensive.
As is well known, a photoelectric level switch detects the presence or absence of liquid at a specific point. It can replace manual liquid level detection. The photoelectric level switch sensor contains an infrared LED and a photodetector. The light emitted by the LED is directed to a prism at the top of the sensor. If there is no liquid, the light is reflected directly from the prism back to the receiver. When liquid enters the prism, the light refracts into the liquid, causing the receiver to receive little or no light. This change is detected by sensing this change. The receiver can then activate the internal photoelectric level switch, triggering an external alarm or control circuit.
The LLC200D3SH level sensor provides single-point level detection with a TTL-compatible push-pull output. Its sensor design incorporates an infrared emitter and a detector, precisely positioned to ensure excellent optical coupling in air. When the sensor's conical end is immersed in liquid, the infrared light is transmitted through the conical surface, weakening the light intensity reaching the detector. Furthermore, this LLC series of photoelectric level sensors (industrial grade, photoelectric immersion sensor) is designed for heavy-duty industrial environments. This series is suitable for wide voltage ranges and can drive currents up to 250mA. Therefore, this series of sensors can directly drive alarms and other devices.
