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 ...

(1) The principle of physical optical fiber sensor, which uses the sensitivity of optical fiber to environmental changes to convert the input physical quantity into a modulated optical signal. Its working principle is based on the optical modulation effect of optical fibers, that is, the optical fiber's response to external environmental factors, such as temperature, pressure, electric field, ...

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...

High sensitivity Lightweight and flexible, easy to install and buried Electrical insulation and chemical stability. Optical fiber itself is a highly insulating and chemically stable substance, which is suitable for harsh environments such as high-voltage isolation and flammable and explosive in power systems and chemical systems Good security ...

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) When the target to be measured is not perpendicular to the transducer of the sensor. This is because the target of the ultrasonic test must be within an angle of no more than 10° perpendicular to the sensor. (2) When a small beam diameter is required. Because the diameter of the general ultrasonic beam is ...

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.

There are three basic components of a fiber optic sensor network, one of which is called a single-point sensor. An optical fiber only plays the role of transmission here, and the other is called a multi-point sensor, where an optical fiber strings many sensors together, so that many sensors can share a light source to achieve networking.

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.

Depending on how the actuator acts, there are three most common types of emergency stop switches. Pull Release: Push in the actuator to stop and release by pulling the actuator backwards. Torsional Release: Push the actuator in by torsional actuator to stop and release. Key Release: Perform ...

The static characteristics of a sensor refer to the performance of the sensor in a static state, which is an important indicator to measure the sensor. The static characteristics of a sensor include linearity, repeatability, hysteresis, accuracy, sensitivity, threshold and resolution, drift, and more. 1. Linearity refers to the sensor measurement ...

(1) Fork photoelectric sensor Placing an optical transmitter and a receiver facing each other on either side of a slot is a fork photoelectric. The luminaire emits infrared or visible light, and the light receiver receives the light in an unobstructed condition. But when the detected object passes through the slot, the light is blocked ...

Superior color contrast sensitivity, detecting contrast as low as 2% over a wide range of colors Excellent performance in low-contrast or high-gloss applications Ultra-fast 10 kHz switching frequency (10,000 starts per second) with 15μs repeatability Robust and durable zinc ...

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...

Infrared sensors are sensors that use the physical properties of infrared rays to make measurements. Infrared, also known as infrared light, has the properties of reflection, refraction, scattering, interference, absorption, etc. Any substance that has a certain temperature above absolute zero can radiate infrared rays. ...

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.

1. Understand the basic wiring principle of photoelectric switch sensors. Photoswitching sensors typically have three pins: the power pin (V+), the power ground pin (V-), and the output pin (OUT). The power pin is used to connect to the positive terminal of the power supply, the ground pin of the power supply is used to connect to the negative terminal of the power supply, and the output pin ...

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, 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 ...

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 ...
