Eberspaecher electrical components Germany Eberspaecher model Eberspaecher price

Eberspaecher electrical components refer to the aggregate of service equipment provided for a specific group of traffic sources, such as trunk lines, switching devices, control systems, etc. The basic research content of traffic theory is to study the relationship between traffic volume, call loss, and bundle capacity; therefore, the line bundle is an important basic concept in traffic theory. A traffic source is the service object of the line bundle, usually referring to user equipment; in a broad sense, the upper-level equipment is the traffic source for the lower-level equipment. In telephone communication, the traffic source is also called the call source, and the number of service devices contained in the line bundle is called the bundle capacity. Figure 1 is a schematic diagram of the line bundle. The capacity of this line bundle is V, and it provides service for N traffic sources. Any traffic source initiating a call can occupy an idle service device in the line bundle.

Eberspaecher electrical component features

Among various types of switches, there is a component with the ability to "sense" objects approaching it—the displacement sensor. Utilizing the sensitivity of the displacement sensor to approaching objects achieves the purpose of controlling the switch to turn on or off; this is the proximity switch. Only when an object moves toward the proximity switch and approaches within a certain distance does the displacement sensor "sense" it, causing the switch to actuate. This distance is usually called the "detection distance." Different proximity switches have different detection distances. Sometimes the detected object moves toward the proximity switch one by one at certain time intervals, and leaves one by one, repeating continuously. Different proximity switches have different response capabilities to the detection object. This response characteristic is called the "response frequency."

Eberspaecher electrical component characteristics

Resolution refers to the ability of a sensor to detect the smallest change in the measured quantity. That is, if the input changes slowly from a non-zero value, when the input change does not exceed a certain value, the sensor output will not change, meaning the sensor cannot resolve the change in this input. Only when the input change exceeds the resolution will the output change. Usually, the resolution at each point within the full-scale range of a sensor is not the same; therefore, the maximum change in input that causes a step change in output within the full scale is commonly used as the indicator for measuring resolution. If the above indicator is expressed as a percentage of the full scale, it is called resolution. Resolution has a negative correlation with sensor stability.

So-called dynamic characteristics refer to the output characteristics of a sensor when the input changes. In practical work, the dynamic characteristics of a sensor are often represented by its response to certain standard input signals. This is because the sensor's response to standard input signals is easy to obtain through experimental methods, and there is a certain relationship between its response to standard input signals and its response to arbitrary input signals; often, knowing the former allows inference of the latter. The most commonly used standard input signals are step signals and sinusoidal signals, so the dynamic characteristics of sensors are also commonly represented by step response and frequency response.
