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. The magnetic tape can be directly pasted on the surface of the equipment, and the two ends are fixed with screws; 2. The magnetic tape can be directly installed in the reserved groove; 3. The magnetic tape can be pasted in the aluminum alloy protective shell provided by the manufacturer, and then the magnetic ruler can be fastened to the equipment with the mounting bracket. ...

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.

The Internet of Things (IoT) is a network based on information carriers such as the Internet and traditional telecommunication networks, which allows all ordinary objects that can perform independent functions to achieve interconnection. Its application fields mainly include transportation and logistics, industrial manufacturing, health care, intelligent ...

1. Physical sensor: A physical sensor is a sensor that detects a physical quantity. It is a device that uses certain physical effects to convert the measured physical quantity into a signal in the form of energy that can be easily processed. There is a definite relationship between the output signal and the input signal. The main physical ...

1. Resistive sensors The basic principle of a resistive sensor is to convert the measured change into a change in the resistance value of the sensing element, and then turn it into an electrical signal output through the conversion circuit. Applications: 1. Strain resistance sensor, used to measure tensile and compressive stress, and other physical quantities based on this...

1. The reason for the total alarm of the sensor The total sensor alarm is when the sensor's alarm indicator is always on, but the sensor is not actually catching the outlier. This can happen for a variety of reasons, but here are some of the most common ones: 1. Sensor device ...

On September 18, 2018, the 14th MM New Automation Forum 2018 was successfully held at the Purple Mountain Hotel in Shanghai, hosted by the mechanical media MM Modern Manufacturing magazine. The theme of this forum is to take data as a starting point and make manufacturing more excellent, emphasizing the excellent manufacturing of digital practices. By dividing ...

1. First, power off the sensor and remove it. 2. Use a clean cotton swab dipped in an appropriate amount of anhydrous alcohol and quietly scrub the reception window. Be careful not to use water or organic solvents to avoid damaging the sensor. 3. After scrubbing, use a clean cotton swab to accept ...

Professional color numerical analysis can meet customers' needs for accurate color quality control With a long measuring range of up to 400 mm, the QCM65 series of sensors solves more challenging applications and is a real problem solver. Reliable detection of up to 31 types of ...

1. Application in industrial automatic detection and automatic control system Sensors play an extremely important role in industrial automation production. In the petroleum, chemical, electric power, steel, machinery and other processing industries, sensors are responsible for detecting various information.

1. If the electronic ruler has been used for a long time, and the seal has been aged, and there are many impurities mixed with it, and the water mixture and oil will seriously affect the contact resistance of the brush, which will make the displayed numbers keep jumping. At this time, it can be said that the electronic ...

When choosing a pressure sensor, we need to consider its comprehensive accuracy, and what are the aspects that affect the accuracy of the pressure sensor? In fact, there are many factors that cause sensor error, and we will pay attention to four unavoidable errors, which are the initial error of the sensor. Head...

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 ...

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. Action time The time from closed to open of normally closed contact is much shorter than the time of normally open contact from natural state to closed, which is particularly important when emergency stop is required in the event of danger.

1. Flange fixed installation Flange mounting is to connect the pressure sensor to the flange and fix the flange to the measured object. The advantage of this installation method is that it is simple in structure, easy to install and disassemble, and suitable for occasions where frequent sensor replacement is required. But...

1. Resistive type A resistive sensor is a device that converts measured physical quantities such as displacement, deformation, force, acceleration, humidity, temperature, etc. into resistance values. There are mainly resistive strain, piezoresistive, thermal resistance, thermal, gas-sensitive, moisture-sensitive and other resistive sensing.

1) Large adjustable range, up to 10,000ppm, a wide range of sensors can be used; 2) Programming through simple circuits and easy-to-use software; 3) Pressure sensors are manufactured in a unique way and are specifically designed to meet industrial needs; 4) Sensors ...
