How the photoelectric level switch controls the laser particle size analyzer to automatically absorb water

The laser particle size analyzer is an instrument that analyzes the particle size through the diffraction of particles or the spatial distribution of scattered light (scattering spectrum). It adopts Furanhofer diffraction and Mie scattering theory. The test process is not affected by temperature changes, medium viscosity, sample density and surface state, etc. Affected by many factors, as long as the sample to be tested is uniformly displayed in the laser beam, accurate test results can be obtained.In addition, as a new type of particle size testing instrument, the laser particle size analyzer is a new generation particle size testing instrument integrating laser technology, computer technology, and optoelectronic technology due to its outstanding characteristics such as accuracy and reliability, fast testing speed, good repeatability, and easy operation. already

The laser particle size analyzer has a reliable circulation dispersion system such as a wet circulation dispersion system, including an anti-dry-burning ultrasonic disperser, a centrifugal circulating pump, an automatic water inlet system, an automatic drainage and overflow system, which is suitable for all samples and ensures that the samples are fully dispersed. Ensure the accuracy and repeatability of the test. The following editor of Gongminwang will briefly introduce how the photoelectric liquid level switch controls the laser particle size analyzer to automatically absorb water.

How the photoelectric level switch controls the laser particle size analyzer to automatically absorb water

The automatic water absorption technology is superior to the automatic water intake technology because the automatic water absorption technology pumps water from the bucket into the circulating pool, which can ensure the water quality and is flexible and convenient. A suction pump and a water level measuring device are installed in the laser particle size analyzer. The water inlet valve is to control the water inlet of the water inlet pipe (connected to water sources such as tap water pipes), which can automatically suck water from the bucket into the circulating pool to realize the test and flushing process. The automatic water intake.

For the water level detection, the automatic water intake process is monitored. When the water level of the sample pool exceeds the water level limit set by the water level gauge, the water intake valve is immediately closed, the water intake is stopped, and the water level full alarm signal is sent to the computer. If the British SST photoelectric liquid level sensor/photoelectric level switch-LLC200D3SH provided by Gongcai.com is installed in the liquid level detection device, the alarm device will be more complete.

It is well known that the photoelectric level switch is a switch that detects the presence or absence of liquid at a certain point and the photoelectric level switch can replace the manual detection of the level. The photoelectric level switch sensor contains an infrared light-emitting diode and a photoelectric. receiver. The light emitted by the LED is guided into the prism on the top of the sensor. If there is no liquid, the light emitted by the LED is directly reflected from the prism back to the receiver. When the liquid is immersed in the prism, the light is refracted into the liquid, so that the receiver cannot receive or can only receive a small amount of light. Use this working principle to sense this change. The receiver can drive the electrical switch of the internal photoelectric level switch to work, thereby starting an external alarm or control circuit.

LLC200D3SH liquid level sensor provides single-point liquid level detection, with TTL compatible push-pull output. The sensor design contains an infrared emission source and a detector, and the installation position is accurate to ensure that the two achieve good optical coupling in the air. When the tapered end of the sensor is immersed in the liquid, the infrared light will be transmitted out of the tapered surface, and the intensity of the light reaching the detector will be weakened. In addition, the LLC series of photoelectric liquid level sensors (industrial-grade, photoelectric water immersion sensors) are specially designed for industrial applications and can be used in heavy-duty environments in industrial applications. This series of products are suitable for a wide voltage range power supply environment, and the drive current can reach 250mA. Therefore, this series of sensors can directly drive alarms and other equipment.
