As one of the early participants and drafters of Industry 4.0z in Germany, we were involved in the discussion of the RAMI reference architecture model. Focusing on connectivity and data presentation, through exhibitions and market applications, we have achieved relevant results, collected effective feedback, guided the development of digital products, and further improved customer service quality. On February 1, 2019, the Germany Bejiafu Group officially launched the commercial acquisition of Comtrol. Comtrol, a pioneer in industrial Ethernet communications and IO-LinkGateway products in the United States, is best known for its RocketPort® product family. Comtrol's leading technologies will complement the product portfolio, such as sensor solutions from the Sensorik 4.0® series, as well as interface technologies including AS-Interface, IO-Link master and industrial connectivity.
Through digital transformation and innovation, we share our best practices in Industry 4.0 to better understand and respond quickly to customer needs, provide personalized and targeted services, and build customer application teams based on customer applications. It has become an industry leader among manufacturers of components for process automation. To provide users with a full set of electronic equipment as one, applicable system solutions. Main modules: isolated safety barriers, signal conditioners, fieldbus products, remote control I/O, HART interface, liquid level measurement, positive pressure ventilation and explosion-proof systems, display hazardous area terminals and HMIs, high-power power supplies and oil-water separator alarm systems.

No output problems with pressure transmitters – a blessing
1. Assuming that the pressure transmitter and the digital display are used together, and the digital display is not displayed at this time, then the user may say that the pressure transmitter has no output, but in fact, this problem is obvious, and it is unreasonable to hastily determine that the pressure transmitter has no output. Assuming the normal output of the pressure transmitter, ...

Zero drift of high-frequency pressure sensors – we are blessed
There are several reasons for the formation of zero drift of high-frequency pressure sensors:
1. There are bubbles or impurities in the adhesive layer of the strain gauge
2. The function of the strain gauge itself is unstable
3. There are virtual solder joints in the circuit
4. The stress release of elastomers is incomplete; In addition to the magnetic field, ...

Precautions for P+F safety barriers
First, it is necessary to pay attention to the capacitive and inductive resistance of cables and field equipment, explosion-proof is the explosion-proof system, in addition to the need for P+F safety barriers to reach the required explosion-proof level, the energy storage of cables and field equipment is also a key issue. Especially after parametric certification replaces system certification, engineering companies are especially ...

The role and classification of safety barriers
In electrical intrinsic safety explosion-proof (abbreviation: intrinsically safe explosion-proof), we generally divide the workplace into explosion-proof area and non-explosion-proof area. There is the transmission of electrical energy between the explosion-proof area and the non-explosion-proof area, for example, the switches, buttons, sensors, etc. in the explosion-proof area are connected to the non-explosion-proof area through the wires.

Introduction to laser encoders
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, ...

How to choose a pressure sensor – we are blessed
1. Recognize the type of pressure measurement, that is, to measure the gauge pressure, absolute pressure or differential pressure. Gauge pressure refers to the pressure value with atmospheric pressure as the zero point, which can have positive and negative values, positive above atmospheric pressure, and negative below atmospheric pressure. The absolute difference refers to the pressure value with the vacuum as the zero point, and the absolute pressure is as long as the value is positive ...

The wiring method of the photoelectric switch
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 "...

A brief introduction to our sensors
Proximity sensors are a general term for sensors that replace contact detection methods such as limit switches and do not require contact detection of the detected object. It is capable of converting information about the motion and presence of objects into electrical signals. The detection method of replacing the electrical signal includes: using an electromagnetic induction bow to ...

Introduction to the throttle azimuth sensor – Doubleblessed
What is the function of the throttle orientation sensor?
The primary function of the throttle azimuth sensor is to detect whether the starting motor is in the idle condition or the load condition, and whether it is in the acceleration condition or the deceleration condition. The shaft of the resistor is linked to the throttle, it has two contacts: a fully open contact and an idle ...

Fault detection of pressure sensors – we are blessed
First, the first component blocking may be the wrong way of the device, the pressure point is unreasonable, so we often emphasize that the device must be the correct device, once the installation is wrong, maybe the installation is not good, it will bury endless hidden dangers for the back. What are the primary components? Orifice plates, remote transmission measuring joints, etc.

Vibratory load cell performance – we are blessed
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.
