ifm sensors detect objects contactlessly

The ifm O2I series of 2D barcode readers recognises 1D and 2D rectangular codes for product tracking, production control and product identification. It can be widely used in the automobile industry, photovoltaic equipment manufacturing, food industry, logistics and transportation, printing machinery and other industries. ...

Modern sensors are very different in principle and structure, how to reasonably select sensors according to the detailed measurement intention, measurement objectives and measurement environment, is the first problem to deal with when carrying out a certain quantity measurement. When the sensor is confirmed, the corresponding measurement method ...

The conversion of the pressure to the electrical signal is done by the physical deformation of the strain gauge, and the strain gauge is bonded to the diaphragm of the pressure sensor and wired into a Wheatstone bridge structure. The pressure exerted on a high-frequency pressure sensor causes the diaphragm to flex, which causes the strain gauge to strain. Strain will occur ...

1. Proximity switch selection Different types of proximity switches should be selected for different raw material detectors and different detection intervals to have a high-performance price ratio in the system, for which the following principles should be followed in the selection: 1. When the detector body is metal material, the high-frequency oscillation type should be selected.

The pressure sensor usually refers to the component-level product of non-standard mV signal output, which is the core component of the pressure transmitter. Due to the weak signal, the demand increases at longer intervals.

Programmable ifm controllers operate using a "sequential scan, continuous loop" approach. 1. Output rewriting stage: When the instruction is fulfilled, the on-off status of the output status register is sent to the input in the output rewriting stage.

In the food and beverage industry, level measurement of a wide range of tanks is critical, but there are many challenges. For example, steam, condensate, temperature changes, or various gases (maintenance gases such as nitrogen) above the level surface in some tanks can affect the accuracy of the measurement.

The magnetic switch is different from our common switching devices, it is also called a magnetic switch, which is a line switching device that uses magnetic field signals to control. Perhaps many people will be interested in this new type of switch, so let's make a detailed explanation of the operating principle of the magnetic switch. ...

There are two types of accelerometers: one is the angular accelerometer, which is improved from the gyroscope. The other is a linear accelerometer. It can also be divided into single-axis, dual-axis and three-axis accelerometers according to the measurement axis. ...

2.1 Inspection interval Detect the stop, start and orientation of elevators and lifting equipment; Detect the orientation of the vehicle to avoid collision between two objects; Detect the setting orientation of the operating machinery and the limit orientation of the moving machine or components; Detect the abort azimuth of the rotary body, the opening or closing of the valve; Detection of cylinders or hydraulic ...

The differential pressure transmitter is a transmitter that measures the pressure difference between the two ends of the transmitter, and outputs a standard signal (such as 4-20mA, 1-5V). The difference between the differential pressure transmitter and the general pressure transmitter is that they have 2 pressure interfaces, and the differential pressure transmitter is generally divided into positive pressure end and negative pressure end.

The operation of the barrier switch should focus on avoiding pulling and closing the knife switch with load, and avoiding closing the knife switch with grounding. The correct order of operation is: Power transmission operation sequence, check the circuit breaker in the open position, first close the bus (power supply) side knife switch ...

1. The scale of the sensor: (1) In normal use (static test or quasi-static test, the frequency of use is not high), the scale of the sensor should be selected to consider the force value of the measurement, but also consider the weight of the auxiliary tool (test fixture) and so on.

IFM sensor is a sensor with optoelectronic devices as the conversion element, which can be used to detect non-electric amounts that directly cause changes in light quantity, such as light intensity, illuminance, radiation temperature measurement, gas composition analysis, etc.; It can also be used to detect other non-electric charges that can be converted into changes in the amount of light, such as part diameter, surface ...

Pressure transmitter is the most commonly used sensor in industrial practice, which is widely used in various industrial automatic control environments, touching water conservancy and hydropower, railway transportation, intelligent buildings, production automation, aerospace, military industry, petrochemical, oil wells, electric power, ships, machine tools, pipelines and many other occupations. ...

Many people are stupid and can't tell the difference between the liquid level sensor and the liquid level switch, and even think that they are the same instrument. In fact, there is a big difference between them. The level sensor does not necessarily display the liquid level, but outputs the liquid level in the form of an electrical signal. The liquid level controller is based on the liquid level sensor ...

Not all damaged bearings can be corrected, but the cause and extent of the damage to each damaged bearing must be evaluated to prevent or reduce further damage before considering the correction or replacement of a new bearing. There are many reasons for bearing damage, such as improper equipment, dirt invasion, etc.

(1) When the strain limit increases with the strain, the nonlinearity of the output of the strain equipment increases, and the error reaches 10%, the strain limit of the strain equipment is general. (2) After the mechanical hysteresis sensitive grid, subbase and adhesive layer are subjected to mechanical strain, they will generally ...

With the continuous development of flow sensors, more and more types of flow sensors are gradually coming out, and they have their own advantages and disadvantages, flow sensors. 1. Advantages (1) The flow sensor can be used to measure industrial conductive liquids or slurries. （2 ...
