Sick Sensors - Classification and detailed introduction of temperature sensors

1. NTC RTD Sensor: This type of sensor is a negative temperature coefficient sensor, that is, the sensor resistance decreases with the increase of temperature. 2. PTC RTD sensor: This type of sensor is a positive temperature coefficient sensor, that is, the sensor resistance increases with the increase of temperature ...

Infrared sensors: Sensors that take advantage of the physical properties of infrared rays to make measurements. Infrared light is also known as infrared light. The infrared sensor does not have direct contact with the measured object during measurement, and the anti-interference performance is poor, so the lens needs to filter the infrared light before measurement, and it needs to be calibrated regularly. ...

Capacitance – As the name suggests, these sensors work by recording changes in capacitance, which is a function of charge and voltage between two surfaces with an air gap or other material known as the dielectric constant. When the object to be measured enters the sensor field, it has an impact on the medium.

1. When the load exceeds the action current, the circuit will be automatically cut off. 2. After the circuit is automatically cut off, the panel indicator light is on, which is convenient for judging the fault part. 3. After troubleshooting, press the red button at the bottom of the panel to restore the normal power supply. 4. For other reasons, the shell ...

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.

1. Self-regulation. At the beginning of use, please check whether the switch itself is defective and whether the appearance is defective. 2. When avoiding obstructions. When the photoelectric switch is used, for some goods such as colored goods, goods with weak reflectivity, and goods with large gaps between small pieces...

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. The pressure goes up, the output of the transmitter does not go up to this situation, you should first check whether the pressure interface is leaking or blocked, if you admit that it is not, check the wiring method and check the power supply, if the power supply is normal, then simply pressurize to see if the output changes, maybe observe whether the zero position of the sensor has an output, if there is no ...

1. Wiring There are 4 outgoing wires of the 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. The lines are not ...

1. Piezoelectric pressure sensor Based on the piezoelectric effect, electrical components and other machinery are used to convert the pressure to be measured into electricity, and then perform related measurement work. Piezoelectric sensors can only be used for dynamic measurements. Host...

1. Laser ranging sensor 2. Measuring distance range 0.5-300 meters, 3000 meters (to use reflector) 3. The accuracy error of the whole process is 20 mm 4. The continuous service life of the laser is more than 50,000 hours (5 years) 5. Standard RS232, RS422 ...

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. ...

(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 ...

(1) Since the inspection can be carried out in a non-contact manner, it does not wear or damage the object to be inspected. (2) Since the contactless output method is adopted, the life extension (except for the magnetic type) is made of semiconductors, and the life of the docking point is not affected. (3) It is not the same as the light detection method.

Reasons for false detection: 1. The installation distance is inappropriate Different from the identification of the reflective intensity of ordinary photoelectric switches, because the color mark sensor recognizes the grayscale contrast, if the measured material is not placed within the detection distance, its sensitivity (grayscale recognition ability) is significantly reduced, and even cannot be ...

advantage Processes are more transparent and machine downtime is less The Multi Physics Box enables Condition Monitoring. Whether it's motors, pumps, conveyor belts or fans – the measured values of temperature, vibration behavior and shock show the phase...

1. The color sensor, also known as the color sensor, is a machine that compares the color of the object with the reference color that has been taught earlier to detect the color. The standard color measurement method is to use a spectrophotometric colorimeter to measure the tristimulus value of the sample, so as to obtain the color of the sample.

1. There are many types of displacement sensors, and the measurement accuracy, service life, response frequency and applicable occasions of sensor products designed with different principles will be slightly different. Appropriate displacement sensor products should be selected according to the on-site installation and measurement requirements. 2. The measurement range of the displacement sensor is one ...

1. Parking lot or conveyor and other places Its function is to detect the parking position, and the detection distance is relatively long, which is more applicable in parking lots and other occasions. 2. The position of the processed parts In the factory production process, in order to realize the automatic processing state of the parts, the position of the parts must be inspected.

The Chinese start-up Youibot relies on the nanoScan3, a proven mobile platform control solution from SICK, for this purpose. Ultraviolet light is harmful to the skin and eyes, but it is very effective in killing viruses. Therefore, the application of ultraviolet light in space disinfection is very wide, and it is also very successful.
