Common infrared sensors can be divided into thermal sensors and photonic sensors. 1. Thermal sensor The thermal sensor is the use of incident infrared radiation to cause the temperature change of the sensor, and then make the relevant physical parameters change accordingly, by measuring the change of the relevant physical parameters to determine the ...

According to the modulation form of the light measured object, it can be divided into: intensity modulation type, polarization state type, phase type and frequency type; According to whether the light interferes or not, it can be divided into: interference type and non-interference type; Depending on whether it is possible to continuously monitor the measured as the distance increases, it can be divided into ...

1. Non-contact detection, the sensor has a long service life and no damage to the inspected object. 2. It is used for long-distance detection and has a wide range of uses. 3. There are many types of objects to be inspected, including objects that have an impact on light propagation. 4. High response frequency, suitable for high-speed assembly line ...

1. Ordinary metal straight tube package temperature sensor The packaging form of this temperature sensor is mostly used in a simple installation environment, and is divided into high temperature temperature sensor, medium temperature or ordinary temperature sensor and low temperature temperature sensor according to the measured temperature range.

What is an ultrasonic sensor? Ultrasonic sensors are industrial control devices that use sound waves above 20,000Hz that exceed the range of human hearing to measure and calculate the distance from the sensor to the target object. How do ultrasonic sensors work? The sensor has a ...

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 ...

Pressure sensors are mainly used in: booster cylinders, boosters, gas-liquid booster cylinders, gas-liquid boosters, presses, compressors, air conditioning and refrigeration equipment and other fields. 1. It is applied to hydraulic system The pressure sensor is mainly used to complete the closed-loop control of the force in the hydraulic system. When the control ...

(1) Measurement of absolute air pressure by electronic means makes the control of the inflatable state of the line more complete and continuous. (2) From the dynamic and static aspects, the air leakage point can be estimated in advance. (3) Determine the change in time of the pressure inside the cable, so that the inflatable ...

1. Add a protective cover as much as possible, and clean up the chips and oil splashed on the ruler in time to strictly prevent any foreign matter from entering the inside of the grating ruler sensor housing. 2. When plugging and unplugging the grating displacement sensor and the plug holder of the digital display, the power should be turned off. 3. For the extension of the dust seal ...

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 ...

How to use the emergency stop button 1. When there is an emergency on the scene, press and lock the red mushroom head button switch or round button switch; 2. Use the safety lock to lock the emergency stop button cover. The role of the emergency stop button 1. Make the machine in any case, immediately ...

1. There is no display on the digital display after connecting the power supply (1) Check whether the power cord is broken and whether the plug contact is good. (2) Whether the power fuse of the digital display meter is blown. (3) Whether the power supply voltage meets the requirements. 2. The digital display table does not count (1) Passing ...

1. Fully 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 is not in the sensitive area, hold down the "SET" key for three seconds, there is a ...

(1) When the grating ruler displacement sensor is connected to the digital display table, the power must be cut off, and the power supply will be provided after the plug is linked. (2) The grating ruler displacement sensor should prevent foreign objects from entering its interior, including water, oil, dust, etc., so a protective cover should be installed as much as possible outside. (3) Periodic inspection ...

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. 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 ...

1. Use the 4 fixing screw holes at the bottom to install directly or add protection or other mechanical use according to the needs of the site and machine installation space facilities. 2. When installing the stainless steel cable, it is necessary to pay attention to the horizontal angle, that is, to make the mechanism of the steel cable from the outlet to the moving part as much as possible, and slide horizontally during work.
