Turck's proximity switch fault phenomenon

Turck's linear displacement sensors have an additional measuring stroke of 100 to 4500 mm. It uses the magnetoelastic principle and non-touch measurement method, and provides a high accuracy of μm according to the 16-bit D/A conversion resolution. It can be changed according to the actual application needs through a very simple programming method.

1. Mechanical damage The most common problem in servo response encoder is a variety of mechanical damage, including hardware damage to the internal component structure of the encoder (code disc, shaft and bearing, etc.) due to mechanical oscillation, collision, impact, wear and tear. 1) Oscillation Pass...

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-- ...

For example, the number of the type: Ni12U-M18M-VP4X-H1141 is divided into 6 parts Part I: Ni12U Letter N: The device method of the sensor is (non-flush device method) Electricity...

Torque sensors are able to convert the physical change of torque into accurate electrical signals, which are mainly used in the power range, and have the characteristics of long service life, high accuracy and strong reliability. Torque sensors are not common in our daily lives, but their use is very important. Currently, the twist ...

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. ...

When there is a problem with the sensor, do you know what went wrong and what is the cause of the problem? There are four main types of sensor problems, namely complete failure problems, fixed error problems, drift error problems, and accuracy degradation problems. ...

1. Estrangement Do not press or touch the barrier as this may damage or alter its calibration, especially on low pressure scale types. 2. Accessories and hardware With the right pressure, additional fittings and hardware, make sure you have the right thread type and size. If the demand ...

In modern industrial production, especially in the process of automated production, it is necessary to use various sensors to monitor various parameters in the production process, so that the equipment is in normal or optimal condition, so that the product can reach the best quality. Therefore, it can be said that if there are many excellent sensors, modern ...

The selection of load cells mainly includes the following four aspects, namely, the sensitivity of the sensor, the accuracy of the sensor, the stability of the sensor, and the number and range of the sensor. 1. Sensitivity Usually, in the ...

(1) Long detection intervals If the detection interval of more than 10 m is maintained in the through-beam type, other inspection methods (magnetic, ultrasonic, etc.) can be completed. (2) There are few constraints on the detected object Because with ...

1. Avoid scum deposited in the conduit and touch the sensor with corrosive or overheated media. 2. When measuring the gas pressure, the pressure valve should be opened at the top of the process pipeline, and the sensor should also be installed in the upper part of the process pipeline, so that the accumulated liquid can be easily injected into the process.

(1) Whether the temperature of the measured target needs to be recorded, alarmed and automatically controlled, and whether it needs to be measured and transmitted at a distance. (2) The size and accuracy of the temperature measurement range. (3) Whether the size of the temperature measuring element is appropriate. (4) Tested ...

1. Durability The reason why the switch has such a long life is that the switch acts as elastic in the straight direction from the elastic membrane. Despite the millions of activities after the elastic membrane, due to the small creep rate, only 0.1 - 0.3m ...

Dispersion silicon pressure sensor: sophisticated, widely used, cost-effective, gauge pressure measurement is the mainstream, and a few absolute pressure, strong overload and impact resistance, but can only measure the medium below 120 °C. The micro-range accuracy is slightly lower; ...

Inductive sensors Inductive sensors are capable of detecting metal objects in a non-tactile and wear-free manner. To do this, they use high-frequency communication electromagnetic fields to interact with their targets. Their strengths are durability, robustness, high switching frequencies, and long service life. Cause...

The OPC UA communication standard is channel-agnostic, making TBEN-L OPC UA easy to integrate ERP, MES or cloud architectures as well as RFID architectures in controllers. In addition, authorization and integrated security protocols protect the system from unauthorized access and manipulation. ...

1. Composition of the sensor A sensor typically consists of a sensitive element, a conversion element, and a basic conversion circuit, as shown in Figure 1. A sensitive element is an element that can sensitively feel the scene being measured and respond to a definite relationship; The conversion element is to convert the measured touch of the sensitive element into ...

The Ethernet I/O module TBEN-LL-4RMC offers four Interroll EC5000 drum motor drive interfaces, which can control up to 48 motors and is capable of driving special motors up to 48V. In addition, the module provides 4 digital input channels and 4 general-purpose digital channels ( ...

1. For different viewing bodies and different viewing distances of different raw materials, different types of Turck proximity switches should be selected to make them have a high performance-to-price ratio in the system, for which the following criteria should be followed in the selection: ...
