Sick Sensors - Classification of RTD Sensors and Their Characteristics and Uses

1. The signal cable of the sensor should not be arranged in parallel with the strong current power line or control line (for example, do not place the sensor signal line in the same pipe as the strong power line and the control line). IF THEY MUST BE PLACED IN PARALLEL, THEN THE DISTANCE BETWEEN THEM SHOULD BE KEPT AT LEAST 50CM, AND THE SIGNAL ...

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 ...

Thermal resistance is used to measure the temperature of a substance when its temperature changes, and its resistance also changes with the characteristics of the change. When the resistance value changes, the working instrument will display the temperature value corresponding to the resistance value. RTD sensors use the resistivity of conductors or semiconductors to change with temperature.

The reader always gives an error, which can be found in the function block usage documentation. 01. How to download and view The public information of most of Sea's products can be downloaded from the official website without login, please find it in the download area at the bottom of the product homepage. For example, we make ...

It is possible to bypass small obstacles (such as dust) (photoelectric is completely not allowed in this environment). Liquid position can be measured. (e.g. for level monitoring) Transparent objects can be measured. (e.g. presence or displacement of glass) Not affected by the surface of the object ...

1. At present, SICK pressure sensors can be used in combination with computers and instruments to improve operation and reduce errors. The human-machine dialogue function is the main feature of SICK pressure sensors, and the display device and input keyboard equipped with it become the medium for human-machine dialogue. 2. SICK pressure sensing ...

1. Platinum thermal resistance The platinum metal is used as the temperature sensing element, and then together with the inner lead and the protective tube, the platinum thermal resistance temperature sensor is formed. It is also often connected to external measurement circuits, controls, and mechanisms to form a temperature sensor. This sensor has two main ...

In the application of inductive proximity sensors, customers are often trapped by the lack of space to install, and the small parts are too small to be effectively detected, and the IMM miniature proximity sensor provides a variety of application solutions in this type of application. IMM miniature proximity sensor with a richer ...

(1) Fork photoelectric sensor An optical transmitter and a receiver are mounted face to face on both sides of a trough to form a trough 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 ...

1. If the electronic ruler has been used for a long time, and the seal has been aged, and there are many impurities mixed with it, and the water mixture and oil will seriously affect the contact resistance of the brush, which will make the displayed numbers keep jumping. At this time, it can be said that the electronic ...

(1) Automatic calibration: When the workpiece enters the sensitive area of the probe, press and hold 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, hold and hold the "SET" button for three seconds, there is a ...

Photoelectric sensors that use optoelectronic components as sensitive components have a wide variety of types and applications. According to the nature of the output of photoelectric sensors, they can be divided into two categories: (1) The photoelectric measuring instrument made by converting the measured into a continuously changing photocurrent, can be used to measure the intensity of light and the object ...

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 ...

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 ...

Proximity sensors are divided according to their working principle: High-frequency oscillation type, capacitive type, induction bridge type, permanent magnet type, Hall effect type, etc. According to the principle of operation, it can be divided into three categories: High-frequency oscillation type using electromagnetic induction, magnetic force type using magnets, and ...

Overview Identification codes are easy and secure IDM's mobile handheld barcode scanner reliably recognizes 1D and 2D codes, including stacked codes such as PDF417. Depending on the field of application and environmental conditions, a standardized or rugged IP65 degree of protection can be provided.

1. Different definitions: A light sensor is generally a device that can sensitively sense light energy from ultraviolet light to infrared light and convert the light energy into an electrical signal. Photoelectric sensors are sensors that use an optoelectronic element as a detection element. It first converts the measured change into light ...

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) 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.
