The resolution of the industrial lens refers to the maximum resolution as a parameter, which is usually marked on the product. Because the resolution can be accurately calculated, through reasonable optical design and high-quality technology, lenses with different resolutions can be produced, matched with industrial cameras, and then applied to different fields that require image recognition.

Electric actuators are important devices in automatic control systems. Due to the limitation of use conditions, maintenance level and installation location, the control accuracy of electric actuators is generally about 3%, and some even exceed 5%, which seriously restricts the improvement of system adjustment quality. For fast-response control systems, it is even more important to improve the control accuracy of electric actuators. ATO various electric actuators are mainly used to control the working conditions of media such as gas, tar, steam, water, and waste gas. In production practice, according to different influencing factors, corresponding technical measures were taken, so that the control accuracy of electric actuators all reached more than 2%, and some exceeded 1.2%, which played a great role in improving the control system quality.

The photoelectric smoke detector is composed of a light source, a photoelectric element and an electronic switch. It is developed by utilizing the basic property that the smoke generated during a fire can change the propagation characteristics of light. The photoelectric smoke detector adopts a photoelectric sensor with a special structure design, which has the advantages of high sensitivity, stability and reliability, low power consumption, beautiful and durable, and easy to use. Its circuit and power supply can be self-tested, and analog alarm tests can be performed.

In order to make buildings safer and avoid the probability of fire, most people have installed smoke alarms in buildings, but many people don’t know much about smoke alarms. How can we solve the problem if it keeps beeping? Is the smoke alarm going off for no reason because formaldehyde exceeds the standard? In fact, this has nothing to do with formaldehyde, it may involve a variety of reasons.

Pressure sensors today are more rugged and reliable than ever. Made of stainless steel construction, they provide abundant overpressure protection, improved total error band, and offer negligible orientation and vibration effects. They are ideal for long-term use even in harsh environments of extreme temperature, humidity, and vibration. In the following, ATO industrial automation will introduce some of the common problems with the pressure sensors.

The use of strain gauges can be divided into two methods. One method is to attach the strain gauge directly to the surface of a loaded component. This method is simple, but not sufficiently accurate. The other method is to attach the strain gauges to an elastic element to make a sensor, which is then loaded to establish a functional relationship between the load and the change in resistance. The measured load value is obtained by means of a pre-determined load calibration curve. The result is a more accurate measurement. The results obtained are more accurate.

Globe valve refers to the valve whose closing piece moves along the center line of the seat. According to this form of movement of the valve disc, the change of the valve seat orifice is proportional to the valve disc stroke. As a result, this type of valve is well suited for use as a cutoff or adjustment and throttling. So how to use the globe control valve? In this article, ATO industrial automation will introduce to you.

In the PLC/DCS control system on the industrial site, the measurement signal is often unstable. One is caused by electromagnetic interference, and the other is the infiltration of high-frequency signals. For example, the current signal output controls the inverter, and the high-frequency interference of the inverter infiltrates the signal. Among them, such interference signals make the frequency converter and valves work unstable. Installing a signal isolator between the signal connections of the two devices is one of the methods to solve the influence of electromagnetic interference and high-frequency signal penetration.
