Banner Sensor - Introduction to the function of the color sensor

1. Photoelectric smoke alarm When there is no smoke, the light emitted by the light-emitting diode travels in a straight line, and the phototriode does not receive a signal. There is no output, when there is smoke, the light emitted by the LED is refracted by the smoke particles, so that the transistor receives the light, there is a signal output, ...

1. Piezoresistive pressure sensor Resistive strain gauges are one of the main components of piezoresistive strain transducers. The working principle of metal resistance strain gauge is the phenomenon that the resistance value changes due to mechanical deformation due to the strain resistance adsorbed on the base material, which is commonly known as the resistance strain effect. ...

The QCM series reliably detects distances within a measuring range A single sensor can distinguish up to 12 colors, saving inventory costs The anti-glare version reliably detects highly reflective objects The sensor has an integrated display as well as buttons for intuitive ...

(1) The Ultimate Problem Solver: Solve the most challenging applications by reducing sensor inventory with reliable, durable sensors (2) Regardless of the reflectivity of the target surface, the solution is difficult distance-based applications, including black foam on black plastic, black rubber in front of metal, multi-packing, etc.

1. Photoelectric head dust masking When the photoelectric sensor is operating, it is easy to accumulate dust or oil dirt on the receiving head, resulting in problems such as insensitive sensor response, false triggering or non-triggering, and even failure to operate normally. At this time, we need to clean the photoelectric head. Cleaning method: ...

The most common method of calibrating a temperature sensor, like that of most other sensors, is to place the sensor in an environment with a known temperature that can be accurately determined for a period of time, and then record and check whether the output of the sensor is consistent with the known ambient temperature, and calculate the transmission rate.

1. The working principle and common parameters of the rope displacement sensor The function of a rope-actuated displacement sensor is to convert mechanical motion into an electrical signal that can be measured, recorded or transmitted. The rope displacement sensor consists of a stretchable stainless steel rope wound around a threaded hub with a ...

Modbus is an application-layer protocol that defines a data unit (ADU) that is independent of the underlying network and can communicate over Ethernet (TCP/IP) or serial links (RS232, RS485, etc.) (Ethernet ADUs and serial ADUs are slightly different). On a serial link, the Modbus protocol has two ...

1. The wiring method of various sensors is basically the same, and the pressure sensor generally has a two-wire system, a three-wire system, a four-wire system, and some five-wire systems; 2. The two-wire system of the pressure sensor is relatively simple, one wire is connected to the positive pole of the power supply, and the other wire is the signal line through the instrument.

1. Prevent the debris from being deposited in the catheter and the sensor from coming into contact with corrosive or overheated media. 2. When measuring gas pressure, the pressure intake should be opened at the top of the process pipeline, and the sensor should also be installed in the upper part of the process pipeline, so that the accumulated liquid can be easily injected into the process pipeline. ...

Insulated from dirt, magnetic, sound, pressure, temperature, acceleration, gyroscope, displacement, liquid level, torque, photoacoustics, current, fiber optic sensors can be used for displacement, vibration, rotation, pressure, bending, strain, velocity, acceleration, current, magnetic field, voltage, humidity, temperature, sound field, current...

01. Application of pressure sensor in weighing system In industrial control, pressure sensing technology is increasingly being used in commercial weighing systems. In many control processes, it is often necessary to collect pressure signals and convert them into electrical signals that can be automatically controlled.

PEOPLE CAN HEAR THE SOUND DUE TO THE OSCILLATION OF THE OBJECT, ITS FREQUENCY IS IN THE RANGE OF 20HZ-20KHZ, BEYOND 20KHZ IS CALLED ULTRASOUND, BELOW 20HZ IS CALLED INFRASOUND. THE COMMONLY USED ULTRASONIC FREQUENCY IS TENS OF KHZ-TENS OF MHZ. Ultrasonic is a type of mechanical vibration in an elastic medium ...

1. Fully automatic calibration When the workpiece enters the sensitive area of the probe, hold down the "SET" button for 3 seconds, and the sensitivity value will be set and displayed in green 2. Two-point calibration When the workpiece is not in the sensitive area, hold down the "SET" key for three seconds, there is a ...

Depending on the mode of exercise Linear Position Sensor: The function of a linear displacement sensor is to convert the linear mechanical displacement into an electrical signal. In order to achieve this effect, the variable resistance slide rail is usually fixed on the fixed part of the sensor, and the displacement of the slide on the slide rail is measured.

1. Fully automatic calibration When the workpiece enters the sensitive area of the probe, hold down the "SET" button for 3 seconds, the sensitivity value will be set and displayed in green 2. Two-point calibration When the workpiece is not in the sensitive area, hold down the "SET" key for three seconds, there is a ...

China (Beijing) International Industrial Intelligence and Power Transmission and Automation Exhibition (IAMD BEIJING) will be grandly opened at the Beijing Exhibition Center from May 9 to 11. As a representative exhibition of the industrial automation industry, IAMD Beijing has accumulated considerable influence after development. The State of United States ...

Provide measurement and control solutions, process measurement needs, and provide a solid data foundation for industrial automation production. This article describes the applications of four typical laser sensors. Laser Sensor: A sensor that uses laser skills to measure. It consists of a laser, a laser detector and a measurement circuit ...

1. Long detection distance If the detection distance of 10 m or more is retained in the through-beam type, it is possible to achieve detection that is not possible with other detection methods (magnetic, ultrasonic, etc.). 2. There are few restrictions on the detected objects Due to the detection of shading and reflection caused by the detection of objects ...
