Sensor selection criteria – Turck

1. Thermocouple Thermocouples are the most commonly used temperature sensors for temperature measurement. Its main benefits are a wide temperature scale and adaptability to a wide range of atmospheric environments, and it is robust, inexpensive, does not require electricity, and is also the cheapest. A thermocouple consists of two different metal wires connected at one end (metal A and ...

1. The AC contactor can be used as a substitute for the DC contactor in an emergency, and the suction time can not exceed 2 hours (due to the poor heat dissipation of the AC coil than the DC, which is determined by their different structures).

Turck's PT1000/2000 series pressure sensors are now available with an IO-Link interface and two programmable switching outputs. In addition to the series' ability to withstand shocks, pressures, and temperature changes, the new products also offer all the advantages of digital communication, including enhanced ...

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

1. According to the measurement target and measurement environment In order to carry out a detailed measurement work, it is necessary to first consider the principle of the sensor to choose, which needs to be analyzed and many elements can be confirmed. Because, even if the same physical quantity is measured, there are sensors with multiple principles to choose from.

1. Understand the circuit principle and determine the maintenance plan: when the electrical system of a piece of equipment is defective, do not rush to disassemble it, first of all, it is necessary to understand the phenomenon, process, planning and cause of the defect of the electrical equipment. Understand the fundamental operating principle of the equipment and electrical system, and analyze the ...

The operating principle of metal resistance strain gauge is the phenomenon that the resistance value changes due to mechanical deformation due to the strain resistance adsorbed on the matrix data, which is commonly known as the resistance strain effect. The resistance value of a metal conductor can be indicated by the following formula: where: ρ-- ...

To include a device with a new software channel, Turck is expanding the Q300 series. In addition to the CODESYS-based read/write heads developed for PLC integration, system integrators can now also use Linux-based versions. ...

On June 27, 2018, Turck's Uprox series inductive sensors were awarded the "AI User Praise Award" at the 2018 (18th) Advanced Manufacturing Skills and Car Manufacturing Industry High-Level Forum and Award Ceremony. The award was selected by readers in the car industry, and it took several months to select ...

1. The internal circuit of the sensor is open or short-circuited; 2. The output signal of the sensor cannot change with the change of the vacuum degree of the inlet pipe; 3. The voltage of the output signal of the sensor is too large or too small, and its value violates the stop range. ...

1. The proximity sensor cannot confirm how far the distance between the detected objects is. 2. The switch is installed within the detection interval range, and the signal is sometimes absent (sometimes detectable, sometimes undetectable) in practice. 3. Practice the detection interval and the ...

The load cell is a kind of electrical signal output device that converts the quality signal into a measurable electrical signal, and the load cell will inevitably make mistakes in use, so what is the reason for its error in daily life? 1. Characteristic error: ...

Temperature sensors are widely used in various occupational fields, such as: medical occupations, heavy industry, water treatment, wind power occupations, rail transit, HVAC occupations, energy and environmental protection, food occupations, hydropower stations, petrochemical industry, metallurgical industry, printing and dyeing pharmaceutical and other occupations are used. ...

Assuming that the power supply is normal, it is necessary to carry out simple pressurization to see if the output has changed, perhaps to observe whether the zero position of the sensor has output, assuming that it has not changed, the sensor has been damaged, and vice versa, it is the appearance of the damage or other links of the whole system. ...

The photoelectric effect can be divided into two categories: the external photoelectric effect and the internal photoelectric effect, and the internal photoelectric effect can be divided into the photoconductive effect and the photogenerated volt effect. It refers to the phenomenon that electrons in an object escape from the surface of the object under the illumination of light, resulting in photoelectron emission. Equipment made according to the external photoelectric effect ...

Since September 2020, Turck has expanded its portfolio of general-purpose products to include 2-wire general-purpose inductive sensors. Since the introduction of the universal 3-wire product, the general-purpose product family has been greatly developed, and the product is now used in various types of customers. Pass...

Pressure sensors have been widely used in recent years, many products are in use, according to different types of test pressure, pressure sensors can be divided into gauge pressure sensors, differential pressure sensors and absolute pressure sensors, what are the strain characteristics of pressure sensors? ...

The angular displacement sensor is a model of displacement sensor that uses a non-touch patent plan to effectively improve long-term reliability compared to other traditional angular displacement gauges such as synchronous analyzers and potentiometers. Its unique planning does not require the use of slip rings, blades, touch cursors...

1. Recognize the type of pressure sensor (1) Electromechanical: The internal mechanical structure of the product, the pressure sensor made of springs, levers, dispatching screws, metal housings, etc., and contact module equipment, does not contain processing circuits inside, and the output is the pressure switch side of the switching quantity.

Robots are chaotic machines controlled by computers with similar physical and sensory functions as human beings. Flexible action program; There is a certain level of intelligence; Able to work without relying on human manipulation. So in general, what are the primary sensors that robots contain? ...
