Sick sensors – the advantages of ultrasonic sensors over photoelectric sensors

1. Thermistor sensor temperature measurement Thermistor sensors used to measure temperature are generally simple in structure and inexpensive. Thermistors without an outer protective layer can only be used in dry places; Hermetically sealed thermistors are not afraid of moisture erosion and can be used in harsh rings.

Pressure sensor is the most commonly used sensor in industrial practice, which is widely used in various industrial automatic control environments, involving water conservancy and hydropower, railway transportation, intelligent buildings, production automatic control, aerospace, military industry, petrochemical, oil wells, electric power, ships, machine tools, pipelines and many other industries. ...

Transmitter: An oscillator (usually ceramic, about 15 mm in diameter) vibrates to generate ultrasonic waves and radiate them into the air. Receiver: When the oscillator receives the ultrasonic wave, it generates the corresponding mechanical vibration according to the ultrasonic wave and converts it into electrical energy as the output of the receiver. ...

With the practical application and demand of security protection, the existing 2D protection equipment has gradually been unable to meet the customer's requirements for safety, and the demand for 3D safety equipment is getting higher and higher. Today we are launching a new product from SICK---safeVisionary2.

Photoelectric sensor is a small electronic device, a key element to end the photoelectric conversion in various photoelectric detection systems. It is a sensor that uses the various properties of light to detect the presence or absence of objects and changes in the surface state. Photoelectric sensors are non-contact, fast responding, and functionally reliable.

The load cell is a relatively easy to damage component in the weighing cell, and it is easy to cause damage to the sensor due to impact, overload, aging, high temperature, corrosion, etc. (1) Physical observation: observe whether the appearance of the load cell is deformed, cracked, etc. (2) Measure the resistance ...

1. Industrial sensors The SICK industrial sensor portfolio includes the widest range of photoelectric sensors, fiber optic amplifiers, color mark sensors, proximity sensors, magnetic cylinder sensors, and measuring light curtains in the automation sector, which are mainly used for: recording, counting, classifying, and positioning objects.

(1) 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 does not enter the sensitive area, press and hold the "SET" button for three seconds.

1. Application of photoelectric sensor in high-voltage and high-current testing In recent years, the use of optical equipment for high-voltage and high-current measurement has developed rapidly in the power system, and many new photoelectric sensor systems have been put into on-site operation, bringing many convenient measures for the monitoring of high-voltage and high-current.

Principle: Contrast sensors are often used to detect spots on specific color marks or objects, and they are used to detect color marks by comparing them to non-color mark areas, rather than directly measuring color. The color mark sensor is actually a reverse device, where the light source is mounted perpendicular to the target object, and the receiver is connected to the ...

First, the transmission effect Through the photoelectric sensor, it can be very good to complete the transfer between the media, which is a very popular way of action in many industrial fields and enterprises, because some energy can not be transmitted manually and can only be reached by machines.

How fork photoelectric sensors work: 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 trough ...

1. There are 4 wires for the wiring sensor, among them, the red or brown wire is connected to the positive power supply, and the black wire is connected to the negative power supply; The green or blue wire is the dark output line, and the white or yellow wire is the bright output line, the user can choose one of them according to his needs, and the other is not used, but it should be insulated. Lines are not allowed ...

1. There is a difference between two-wire system and three-wire system for proximity sensors, and three-wire proximity sensors are divided into NPN type and PNP type, and their wiring is different. 2. The wiring of the two-wire proximity sensor is relatively simple, and the proximity sensor and the load can be connected to the power supply after being connected in series. 3. Three-line ...

1. The sensor should be handled gently, especially for the small range sensor with aluminum alloy material as the elastomer, any impact or drop caused by vibration is likely to cause a large output error. In addition, it is necessary to protect the sensor outlet head and not to break it 2. Design loading ...

What are the applications of color sensors? 1. Discrete photodiode with color filter The traditional color sensing method uses a structure in which three to four photodiodes are combined on a single chip, and red, green, and blue filters are placed on the surface of the photodiodes. An independent ...

With the rapid development of "Made in China" to "Made in China", intelligent equipment and other technologies have been widely used in various fields, among which the degree of intelligence in steel structure construction is also getting higher and higher. In the intelligent construction of steel structures, welding and spraying are indispensable process links, in which ...

1. Find the screw at the end of the switch, twist it clockwise to adjust it far, and twist it counterclockwise to adjust it closer. 2. It can increase the intensity of the light source. 3. Improve the sensitivity of the switch sensor. 4. It can also be adjusted according to the instructions for use. ...

(1) Measure the clock signal and data signal of the displacement sensor of 4 hydraulic cylinders, the clock signal is about 2.8V DC and 0.123V AC; The data signals are all about 2.8V DC and 0.245V AC. From this, it can be judged that the PLC clock and MTS data bit transmission and reception pulse loops are normal ...

The logistics industry has always been a strong area of SICK, in response to the detection of various goods on different conveyor lines and the diverse needs of customers, SICK has launched a series of photoelectric sensors such as G6, Z18, W16, W26 and Ray26 - which can detect cartons, baskets, uneven appearance, transparent bottles, laminated bags, etc.
