The selection of safety barriers

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...

The working principle of the straight line is the same as that of the sliding rheostat, it is used as a voltage divider, it is the actual orientation of the measured direction with the relative output voltage. There are the following requirements for the operation of this equipment: 1 ...

Now that the prevention and control of the new pneumonia epidemic has entered a critical period, how can it be useful to reduce cross-infection in hospitals and prevent the spread of the epidemic? Reduce the operational pressure of front-line medical personnel and help prevent and control the epidemic? All of them have become the key policies that have attracted wide attention. From long-distance medical care to intelligent robots ...

In order to select the best liquid level sensor, we need to understand not only the characteristics and conditions of the liquid to be measured, but also the advantages and limitations of different detection methods, and then we can select the most suitable sensor. Here are some of the most common inspection technologies on the market today. ...

Vibrating load cell: When an elastic element is subjected to a force, its natural vibration frequency is proportional to the square root of the force. By measuring the change in the natural frequency, the force of the analyte acting on the elastic element can be calculated, and then its mass can be found. There are two types of vibrating sensors: vibrating wire type and tuning fork type. ...

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...

An accelerometer is an electronic device that measures the force of acceleration and converts it into a signal. It is possible to calculate the skew angle of the device relative to the horizontal plane, and analyze the equipment movement method through the analysis of dynamic acceleration. The requirements for sensitivity are very high, in fact, no matter what type ...

Based on the characteristics of fixed force measurement, the sensor principle structure is selected as a resistance strain force sensor with mature technology and low requirements for the measurement circuit, and the elastomer of one of the key components of the sensor is selected S-beam structure, as shown in Figure 1. When subjected to pressure P, the ...

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 ...

With the gradual growth of demand for torque sensor shopping malls at that time, in recent years, manufacturers and brands producing torque sensors have shown a rapid upward trend.

1. Shielding skills Containers are made from metal materials. Wrapping circuits that require maintenance between them can effectively prevent the disturbance of electric or magnetic fields, which is called shielding. Shielding can be divided into electrostatic shielding, electromagnetic shielding and low-frequency magnetic shielding. 2. Electrostatic shielding ...

Points to note in the selection of proximity switches 1. The working voltage of the proximity switch output is selected, generally DC type DC24V or AC AC250V optional; 2. Proximity switch output method selection, generally NPN-normally open, NPN-...

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.

An encoder is a device that compiles or converts signals or data into signals that can be communicated, transmitted and stored – encoders can be divided into two categories: incremental and absolute. Incremental encoders are the most important way to convert bits ...

PRT (Pulse Ranging Technology) stands for Pulse Ranging Technology, which is currently the most accurate industrial-grade process used to measure intervals. By using this direct measurement method, the measurement range from a few centimeters to several hundred meters can be accurately recorded. ...

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.

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.

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 ...

Encoder: Laser encoder is a general term for encoders with laser as the light source. According to the published material, the principle can be broadly divided into two types, namely the use of the grating method and the use of the Fourier image method. Grating thousand-related method, where a laser of wavelength is projected on a periodic grating at a distance of p, ...

In the early application and selection of sensors, how to choose is a very important point, and the selection is smooth, and the following will briefly talk about how the sensor is selected in the early stage. The use of the sensor in practical operation is relatively common and may be practical ...
