How to deal with the malfunction of the proximity sensor during work

Optical fiber sensor and photoelectric sensor are two typical sensors, which are widely used in production and measurement, so what is the difference between the two? Fiber optic sensor skills are developed on the basis of fiber optics, optical communications, and optoelectronic skills, and electromagnetic...

Proximity switch is a kind of azimuth switch that can be operated without mechanical direct touch with moving parts, when the sensing surface of the object proximity switch to the action interval, the switch can be operated without mechanical touch and any pressure, so as to drive DC electrical appliances or computer (PLC) ...

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, ...

The resistive sensor and the corresponding measuring circuit are composed of force, pressure, weighing, displacement, acceleration, torque and other measuring instruments for metallurgy, electric power, transportation, petrochemical, commercial, biomedical and national defense departments to carry out automatic weighing, process detection and realize the automation of the production process.

The use of angle sensors in practical manipulation is relatively common, and may be useful for the needs of different occupations and different fields. No matter how good the instrument is, there is a quality of the instrument itself, and in order to reduce the presentation of errors in the measurement process, users need to choose a good quality ...

According to the nature of the measurement, sensors can be divided into three categories: physical sensors, chemical sensors and biosensors. Physical sensors: It is the use of certain physical effects to convert the measured energy into energy that is easy to process.

1. The basic output method of torque sensor signal is: square wave signal and pulse signal. Voltage analog signal output or current analog signal output (unidirectional, static torque measurement) can be made according to user needs. 2. Twist ...

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, ...

Measurement accuracy generally refers to the affirmative accuracy of the measurement value of the analog output. Depending on the echo transmission moment, the measurement accuracy of the ultrasonic sensor relies on several physical parameters. These parameters are generally related to air and internal errors. Environment...

1. Classification according to the way of engraving the disc is different (1) Incremental type: that is, every time the angle of the unit is emitted, a pulse signal is emitted (there is also a sine and cosine signal, and then it is subdivided, and the pulse with a higher frequency is chopped), usually the output of phase A, phase B, phase Z, phase A and phase B are ...

1. How to estimate the standard detector body of photoelectric sensors? The thrift-beam type and the regressive reflection type are based on the diagonal length of the optical structure, and the scale of the opaque body with a large diameter is used as the standard object. The general through-beam type is based on the diagonal length of the projector and receiver as the standard detection ...

1. The interval from the launch surface of the probe to the liquid level should be smaller than the range of the purchased surface. 2. The interval between the launch surface of the probe and the highest liquid level should be greater than the blind area of the purchased surface. 3. The launch surface of the probe should be parallel to the surface of the liquid. ...

1. Single-point load cells should be handled with care, especially for small capacity sensors with alloy aluminum as elastomers, any vibration-induced impact or drop is likely to cause large output errors. 2. Design loading ...

First of all, the following points should be paid attention to when wiring the encoder: 1. It is necessary to use a metal cable bracket and ensure that the bracket connection is connected to the ground; 2. The cable should be arranged as close to the metal parts as possible, such as control cabinet panels, beams and metal rails, etc.

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 ...

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 ...

An encoder is a device that converts angular or linear displacement into an electrical signal. The former becomes the yardstick, and the latter is called the yardstick. According to the readout method, the encoder can be divided into two types: touch type and non-touch type. The touch type selects the brush output, and a brush touches the conductive area or the insulating area to represent the shape of the code.

Pressure sensors are used in all walks of life, especially in the industry, many pressure sensors, but the industry generally requires pressure sensors to be able to prevent corrosion, pressure sensor joints and cavities are imported stainless steel for all processing, as the pressure transmitter projectile body of stainless steel material resistance...

Rotary encoders are a class of sensors used to detect the angle of rotation and its derived mechanical parameters, including velocity and acceleration, etc., and can detect transmission movements such as rotation and linear lines. Due to its wide range of applications, rotary encoders convert mechanical inputs into electrical signals, which can be used by counters, tachometers, programmable ...

Photoelectric switches are what we generally call sensors. **Standard GB7665-87 defines a sensor as: a device or device that can sense the specified measured part and convert it into a usable signal in accordance with certain rules, which is generally composed of a sensitive element and a conversion element. The sensor is a ...
