Introduction to the sensor model

Q1: How does the ultrasonic sensor work? Ultrasonic sensors are used to measure the detection function of emitting high-frequency sound pulses that are inaudible to the human ear, which are dispersed in the air into a conical shape and reflected back as soon as they hit an object. Ultrasonic ...

Marine geography Landslides, avalanches -- Dual-axis skew sensor with liquid level sensor for landslide or avalanche monitoring, through wireless data transmission to the central control system, real-time monitoring of mountain conditions, can effectively reduce the damage caused by landslides. Construction ...

Overhead monorail conveyors are used for internal transportation of production materials. They are popular in the car industry, where engines, drivetrains, doors and entire car bodies are transported along the production line, for example. A complete monorail conveyor system is composed of a trajectory system and a plurality of monorail conveyors ...

P+F photoelectric proximity switch is called a photoelectric switch made of the photoelectric effect. The light-emitting device and the photoelectric device are installed in the same detection head in a certain direction. When a reflective surface (the object to be detected) is close to each other, the photoelectric device receives the reflected light and outputs it in the signal, so that it can be "...

Photoelectric switches are what we generally call sensors. **Standard GB7665-87 defines a sensor as: a device or device that can sense the specified measured part and convert it into a usable signal in accordance with certain rules, which is generally composed of a sensitive element and a conversion element. The sensor is a ...

There are two common types of sensor switches: NPN type and PNP type, so let me tell you what are the differences and differences between them? For example, there is a switch VT in the NPN type open collector output circuit, and the output OUT is connected to the power supply 0V through the switch VT ...

1. The definitions are different Photoelectric sensor: A photoelectric sensor is a device that converts optical signals into electrical signals. Its principle of operation is based on the photoelectric effect. The photoelectric effect refers to the phenomenon that when light shines on certain substances, the electrons of the matter absorb the energy of photons and the corresponding electrical effect occurs ...

1. Avoid scum deposited in the catheter and contact the transmitter with corrosive or overheated media. 2. When measuring the gas pressure, the pressure port should be opened at the top of the process pipeline, and the transmitter should also be installed at the upper part of the process pipeline, so that the accumulated liquid can be easily injected into the process.

1. The interval from the launch surface of the probe to the liquid level should be smaller than the range of the purchased surface. 2. The interval between the launch surface of the probe and the highest liquid level should be greater than the blind area of the purchased surface. 3. The launch surface of the probe should be parallel to the surface of the liquid. ...

Photoelectric switches are what we generally call sensors. The definition of the sensor under the national standard GB7665-87 is: the equipment or device that can feel the specified measured parts and convert them into usable signals in accordance with certain rules, generally composed of sensitive elements and conversion elements. ...

Picture sensor is an extremely useful product, which has gradually attracted the favor of shopping malls with its strong sensitivity and speed. The use of picture sensors in daily life is undoubtedly a digital camera product, and its development speed can be described as changing with each passing day. At...

Ultrasonic sensors are used for the inspection of printed circuit boards (PCBs): In this application, ultrasonic sensors are used to inspect printed circuit boards. So what factors need to be considered when installing and installing ultrasonic sensors ...

1. The PCB layout board touches the problem, and when the imitation signal is routed, the imitation signal is not wrapped with imitation, and it is even possible that the signal line and then directly go to the power line, which is easy to receive disturbances. Solution: When it is a board, wrap the GND to imitate the signal line. If there is a model ...

The new base plate has been developed and upgraded according to the technical parameters of the Dark Horse system, and is specially adapted to the HIMax safety system. In addition to their comprehensive functionality, these baseplates also offer the look and feel of the Dark Horse System baseplates for use in non-risk areas. The new product line masks all signal types and ...

In the process of using the safety barrier, whether it is the construction stage or the daily maintenance, repeated removal of the suture is a troublesome and simple mistake. With pluggable terminals, there is no need to repeatedly disconnect the wires. The field side terminals of the safety barrier and the system side terminals are distinguished by different colors, if there are two sets of ...

Technological advantages The HiC2441 is adaptable to any signal type, eliminating the need for messy configuration configurations, allowing users to complete loop commissioning simply, quickly and reliably. The HiC2441 is a universal barrier that can be adapted to any common signal type. Meantime...

1. Grating pollution This will reduce the signal output amplitude, and the oil must be quietly wiped off with absorbent cotton dipped in anhydrous alcohol. 2. Encoder connection cable fault: the probability of this fault is high, and it is often encountered in repair, which should be the priority factor. Generally, the encoder cable is broken ...

Types of load cells: Electrical strain gauge load cells: One widely used principle is the color of a resistive strain gauge (resistance strain gauge), where the resistance is changed to an electrical output, which is then passed through an instrument to measure the mass. Capacitive load cells: low power consumption and low cost. The principle of ...

Strain gauge tension and compression load cells are available in two different input and output wiring methods: The first is the four-wire connection method. The load cell of the four-wire connection method has no special requirements for the secondary instrument panel, and it is very convenient to use, but when the cable is long, it is easy to be shaken by the operating temperature.

The R2 and R3 series of photoelectric sensors are impressive products that characterize a very small housing plan. Robust R2/R3 miniature photoelectric sensors – smaller than a matchbox, space-saving miniature housing photoelectric sensors R2/R3 series ...
