Precautions for P+F safety barriers

What is the reason for the detection signal when no metal object is close to the switch? The magnitude of the electromagnetically induced voltage is proportional to the current of the disturbance source, that is, the larger the disturbance current, the greater the disturbance voltage. If the proximity switch does not adopt any ...

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. ...

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.

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.

Positioning, Navigation, Sorting...... The completion of various functions of mobile robots can be said to be inseparable from the role of sensors, and with the continuous expansion of the scope of use of mobile robots, the environment they face is more complex and diverse, and the requirements for sensors are also constantly improving. ...

Auxiliary mechanical devices: commonly used are rack and pinion, chain belt, friction runner, rope reeling machinery, etc. Low-speed end device: installed behind the reduction gear, such as the shaft end of the winch wire rope drum or the shaft end of the next reduction gear ...

Sensors and transmitters are thermal surface concepts. A sensor is a general term for a device or equipment that can be measured by rules and converted into a usable output signal according to a certain rule, which is generally composed of an active element and a conversion element. When the output of the sensor is a regular canonical signal, then ...

1. Optical adjustment The factory setting of the sensor is the maximum range, and this setting is subject to change. Note: Only use your finger to press the button. ​ 2. Set the range (when aborted) Adjust the sensor with a reflector; ...

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 ...

1. Self-conditioning. At the beginning of use, please check whether the switch itself is defective and whether the appearance is defective. 2. When using the EL130 photoelectric switch to avoid obstructions, some goods such as colored goods. Less reflective goods. Goods with large gaps between small pieces ...

The pulse encoder is a rotary encoder that uses the rotation pulse for signal output, and the main characteristics are the standard shape and diversified shape structure; The internal coding is stable, the signal output qiang, and the pulse value and positioning value are clear. Therefore, when choosing this type of punching encoder, ...

P+F photoelectric proximity switch is called a photoelectric switch made of the photoelectric effect. The light-emitting device and the photoelectric device are installed in the same detection head in a certain direction. When a reflective surface (the object to be detected) is close to each other, the photoelectric device receives the reflected light and outputs it in the signal, so that it can be "...

There are two main types of encoders, incremental encoders and affirmative encoders. The incremental encoder reads the change in the viewpoint displacement, while the affirmative encoder reads the positive viewpoint of the encoding axis. They are done using three common skills, i.e., optical, mechanical, or magnetic. ...

1. If the electronic ruler has been used for a long time, and the seal is now aged, and there are many impurities mixed with it, and the water mixture and oil will seriously affect the contact resistance of the brush, which will make the displayed numbers keep jumping. At this time, it can be said that the electronic ...

1. Temperature Excessive temperature is one of the common causes of differential pressure sensor failure, as there are many components of the differential pressure sensor that can only function properly within the specified temperature scale. During installation, if the sensor is exposed to temperatures beyond these temperature scales, it may be exposed to ...

1) It is recommended to place the pressure sensor and its tee valve at the level of the axillary line, which is used for ventilation and sensor zeroing. 2) Approve the maintenance cap on the three-way valve to be perforated, connect the sensor with the monitor, and follow the instructions of the monitor to ...

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 ...

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 ...

Wiring method of weighing strain tension and compression sensor: Strain gauge tension and compression load cells can be wired 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.
