Selection criteria for proximity switches

Strain gauge tension and compression load cells are available in two different input and output wiring methods: The first is the four-wire connection method. The load cell of the four-wire connection method has no special requirements for the secondary instrument panel, and it is very convenient to use, but when the cable is long, it is easy to be shaken by the operating temperature.

1. Selection of reliability The potential of a sensor to persist in its properties over a period of time is called reliability. In addition to its own structure, the key factor affecting the long-term reliability of the controller is the use of harsh environments. Evil...

Sensor calibration refers to the process of transmitting the standard value expressed by the norm to the indexing of the sensor's operating range, and the indexing is determined. The calibration of the sensor is based on the standard value generated by a standard device (e.g. a known standard force, pressure, torque, displacement, etc.).

Capacitive sensors have the advantages of simple structure, high temperature resistance, radiation resistance, high resolution, and good dynamic response characteristics, and are widely used in the measurement of pressure, displacement, acceleration, thickness, vibration, liquid level, etc. However, it is necessary to pay attention to the following aspects in the application of the influence on the measurement results: ...

Direction and fluid flow velocity sensors are essential for different industrial, medical, and environmental uses. Flow sensors quantify the direction and rate of gas and liquid flow in applications such as density measurement, viscosity measurement, flow pattern determination, and wall shear stress determination. In addition to the flow parameters to the direction, ...

In the field of engineering oscillation testing, there are various test methods and methods, but they can be divided into three categories according to the measurement methods of various parameters and the physical properties of the measurement process. 1. Mechanical quizzes Will the works oscillate ...

In the field of industrial automation, there is always the challenge of connecting the individual sensor components on movable machine components. Regardless of their mechanical structure, the use of e-chains® or slip rings tends to wear or crack slightly. As a result, their durability is limited, and together they cause ...

Eltra incremental encoders fall into three categories: Optical solid shaft incremental encoder Eltra. The couplings in these types are made of solid shafts. · EL-ER 30 E/H； · EH 38 A/B/D； · EL-E ...

Let's start with the conceptual difference, the sensor is a kind of detection equipment, can sense the measured information, and can sense the information, according to the law to change the information into electrical signals or other required information output, in order to satisfy the information transmission, processing, storage, display, recording and manipulation ...

1. The core is different: the core of the communication contactor will suffer eddy current and hysteresis loss, while the DC contactor has no core loss. Therefore, the core of the communication contactor is made of mutually insulated silicon steel sheets, and is often made into an E-shape; The core of the DC contactor is made of a single piece of mild steel, ...

The rotary incremental encoder outputs pulses when it rotates, knows its orientation by the counting device, and remembers the orientation by relying on the internal memory of the counting device when the encoder does not move or the power goes out. In this way, when the power goes out, the encoder can not have any movement, and when the call is working, the encoder ...

The inlet pressure sensor is abbreviated as MAP. It connects the intake manifold with a vacuum tube, and induces the vacuum change in the intake manifold with the different speed loads of the engine, and then converts the change of internal resistance from the sensor into a voltage signal, which is used by the ECU computer to correct the fuel injection amount and ignition timing angle. Other words...

Ultrasonic sensors are used for the inspection of printed circuit boards (PCBs): In this application, ultrasonic sensors are used to inspect printed circuit boards. So what factors need to be considered when installing and installing ultrasonic sensors ...

The isolated barrier can be adapted for PCL applications. If the working environment of the field equipment is relatively bad, resulting in the signal sensing line of the PLC breaking the skin and connecting with other lines of different voltages or shorting to the equipment at the same time, there will be strong electricity into the pIc input port, which will cause the whole module to be burned, resulting in ...

NBB20-L2-E0-V1/ NPN normally open NBB20-L2-E2-V1/ PNP normally open NBB20-L2-A2-V1/ PNP normally open + normally closed NBN40-L2-Z0-V1/ DC two-wire normally open NBN40-L2-E0-V1/ NPN normally open NBN40-L2-E2-V1/ PNP normally open ...

Under normal circumstances, a photoelectric sensor consists of two parts: a processing path and a processing element. Its basic principle is to use the photoelectric effect to convert the measured change into a change in the optical signal, and then use the optoelectronic components to further convert the non-electrical signal into an electrical signal. The "photoelectric effect" refers to the use of light ...

Proximity sensors are a general term for sensors that replace contact detection methods such as limit switches and do not require contact detection of the detected object. It is capable of converting information about the motion and presence of objects into electrical signals. The detection method of replacing the electrical signal includes: using an electromagnetic induction bow to ...

The operation principle and infection of the P+F encoder: it is a modified sensor that converts the change displacement into a series of digital pulse signals, these pulses can be used to control the angular displacement, if the P+F encoder is connected to the gear bar or spiral screw, it can also be used to measure the straight line.

A smooth production process is the policy that every production manager strives to achieve. In order to accomplish this policy, a high-performance automation system is required. With the new FDH-1 handheld bus diagnostic device, you will be on your way to maximizing the availability of your equipment.

Mechanical damage is common in servo response encoder problems, including hardware damage to the internal component structure of the encoder due to mechanical oscillation, collision, impact, wear and tear. Excessive mechanical oscillations may cause damage to the encoder disc, shaft and bearing.
