  The principle of the   laser ranging module   is based on measuring the time it takes for a laser pulse to reach an object and return to the sensor. The specific process is as follows: ‌  Emits Laser Pulses  : The laser ranging module emits short pulses of laser light at the target object, usually using a semiconductor laser (such as a laser diode) to emit narrow coherent light. ‌  Time-of-Flight Measurement  : The laser pulse passes through the air and reaches the target object, when it hits the surface of the object, the laser pulse is reflected back to the module‌. ‌ Receive Reflected Pulse : The module has a built-in photodetector or receiver to detect the reflected laser pulse and convert it into an electrical signal‌. ‌ Time Measurement  : Precise measurement of the time from emission to return of laser pulses by high-speed electronic circuits‌. Distance Calculation  : Using the speed of light (about 299,792 km/s in a vacuum) multipli...

  Introduction:   The wall mounted ultrasonic flowmeter  is a kind of instrument that uses ultrasonic technology to measure the flow velocity and flow rate of the fluid in the pipeline. It adopts a non-contact measurement method and can be applied to a variety of fluid media, especially for transparent or non-transparent, corrosive, conductive liquids have a wide range of applicability. This paper will introduce the working principle of wall-mounted ultrasonic flowmeter in detail.   Working Principle   1. Ultrasonic Beam Propagation Wall-mounted ultrasonic flowmeters emit ultrasonic beams through sensors that propagate into the fluid at a certain Angle and frequency. When the ultrasonic beam encounters suspended particles or bubbles in the fluid, it reflects and scatters. Part of the reflected beam returns to the sensor and is picked up by the receiver.   2.  Velocity and Time Change The propagation speed of ultrasonic beam in fluid is directly related...

  Description: The  microwave material level switch  determines the capacitance value at the end of the sensor and the dielectric constant value of the medium through a high-frequency electric field. because the dielectric constant value of air is different from the dielectric constant value of the medium, and two states can be identified: covered and uncovered. Under normal conditions, the indicator light is off to indicate that it is not covered, and the indicator light is always on to indicate that it is covered, and the switch is switched. This product has the characteristics of compact structure, strong resistance to material hanging, good stability, and wide application for media. Main Parameter:   1. Power Supply: 12-30VDC. 2. Output Mode: NPN/PNP,PWM. 3. Logic Output: NO+NC. 4. IP Grade: IP67. 5. Materials: 316 stainless steel, PEEK probe. 6. Response Time: 0.2s   Features: 1. The sensor design is compact and suitable for installation in confined sp...
