Moeller electrical components Germany Moeller model Moeller price

Moeller 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.

Moeller electrical component characteristics

Sensitivity refers to the ratio of the change in output to the change in input of a sensor under steady-state operating conditions. It is the slope of the output-input characteristic curve. If the relationship between the sensor's output and input is linear, then the sensitivity S is a constant. Otherwise, it will vary with changes in the input. The dimension of sensitivity is the ratio of the dimensions of the output and input quantities. When the dimensions of the sensor's output and input quantities are the same, sensitivity can be understood as the amplification factor. Increasing sensitivity can yield higher measurement accuracy. However, the higher the sensitivity, the narrower the measurement range, and stability is often poorer.

Moeller electrical component types

1, Classification by mounting type: As thermocouples are a primary means of temperature measurement and are widely used, there are various requirements for their mounting devices and technical performance. Therefore, thermocouple mounting devices are divided into six types: no mounting device, threaded, fixed flange, movable flange, movable flange angle form, and tapered protection tube. 8, Classification by assembly and structural configuration: Based on the performance and structural configuration, thermocouples can be classified as: detachable thermocouples, explosion-proof thermocouples, armored thermocouples, and spring-loaded fixed thermocouples for special applications.

Moeller 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 telecommunications 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 users make new call attempts after a failed call, trunks can be divided into repeated-call systems and non-repeated-call systems. Actual communication systems all involve repeated calls; non-repeated-call systems are an approximation of repeated-call systems. ① Full-availability trunks. If any service device (trunk line or selector) in the trunk can be used by any traffic source in the group of traffic sources it serves, such a trunk is called a full-availability trunk. ② Partial-availability trunks. 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.
