MAX MueLLER electrical components Germany MAX MueLLER models MAX MueLLER prices

MAX MueLLER electrical components are tools that can accurately determine and measure temperature, divided into pointer thermometers and digital thermometers. Depending on the temperature-sensing substance used and the temperature measurement range, there are kerosene thermometers, alcohol thermometers, mercury thermometers, gas thermometers, resistance thermometers, thermocouple thermometers, radiation thermometers and optical pyrometers, bimetallic thermometers, etc. Digital thermometers can accurately determine and measure temperature, displaying it digitally rather than with a pointer or mercury. Hence they are called digital thermometers or digital temperature gauges.

MAX MueLLER electrical component classification

Based on structural differences, they are classified into full-availability trunks, partial-availability trunks, and link systems; based on service methods, they are classified into loss-system trunks and waiting-system trunks (see stochastic service systems); based on the number of traffic sources served, they are classified into infinite-traffic-source trunks and finite-traffic-source trunks. In telecommunication systems, equipment directly used for communication between users is mostly an infinite-traffic-source loss-system full-availability link system, while equipment used to control the connection process of communication devices is mostly an infinite-traffic-source waiting-system full-availability system. When the number of traffic sources is not very large relative to the trunk capacity, a finite-traffic-source full-availability system or partial-availability system is generally adopted. Based on the call behavior of traffic sources, i.e., whether new call attempts are made after a user's call fails, trunks can be divided into repeated-call systems and non-repeated-call systems. Actual communication systems all have repeated calls; non-repeated-call systems are an approximation of repeated-call systems. ① Full-availability trunk. If any service device (trunk line or selector) in the trunk can be used by any traffic source in the traffic source group it serves, such a trunk is called a full-availability trunk. ② Partial-availability trunk. If any traffic source in the traffic source group can only use part of the service devices in the trunk, such a trunk is called a partial-availability trunk. Partial-availability trunks divide the traffic source group into several subgroups, performing grading and multiple connections between the outlets of the traffic groups. This structure can be described by the example shown in the figure below.

MAX MueLLER electrical component classification

Printed circuit boards are broadly classified into three categories by layer count: single-sided boards, double-sided boards, and multilayer boards. First, single-sided boards: on the most basic PCB, components are concentrated on one side, while conductive traces are concentrated on the other side. Because traces appear on only one side, this type of PCB is called a single-sided printed circuit board. Single-sided boards are usually simple to manufacture and low in cost, but their disadvantage is that they cannot be applied to overly complex products. Double-sided boards are an extension of single-sided boards; when single-layer routing cannot meet the needs of electronic products, double-sided boards must be used. Both sides have copper cladding and traces, and vias can be used to connect circuits between the two layers, forming the required network connections. Multilayer boards refer to printed boards formed by laminating more than three conductive pattern layers with insulating materials in between, with the conductive patterns interconnected as required. Multilayer printed circuit boards are the product of the development of electronic information technology toward high speed, multifunctionality, large capacity, small volume, thin profile, and light weight. Printed circuit boards are classified by characteristics into flexible boards (FPC), rigid boards (PCB), and rigid-flex boards (FPCB).

MAX MueLLER electrical component applications

Photoelectric sensors that use photoelectric elements as sensitive elements come in many types and have wide-ranging applications. Photoelectric sensors can be divided into two categories based on the nature of their output: (1) Photoelectric measuring instruments that convert the measured quantity into a continuously varying photocurrent, which can be used to measure physical quantities such as light intensity, object temperature, light transmittance, displacement, and surface condition. Examples include illuminance meters for measuring light intensity, photoelectric pyrometers, photoelectric colorimeters and turbidimeters, photoelectric alarms for fire prevention, and automatic inspection devices and instruments for checking the diameter, length, ellipticity, and surface roughness of machined parts, all of which use photoelectric elements as their sensitive elements. Semiconductor photoelectric elements are not only widely used in civil industrial fields but also hold an important position in military applications. For example, lead sulfide photoresistors can be used to make infrared night vision devices, infrared cameras, and infrared navigation systems; (5) Converting the measured quantity into a continuously varying photocurrent. Various photoelectric automatic devices are made using the characteristic of photoelectric elements to output "present" or "absent" electrical signals when exposed to light or no light. Photoelectric elements are used as switching photoelectric conversion elements. Examples include photoelectric input devices for electronic computers, switching temperature control devices, and digital photoelectric tachometers for speed measurement.
