Measuring instruments are technical devices that can measure, monitor and visualise physical, chemical or electrical quantities. They are indispensable for precisely recording data and optimising processes in science, industry, medicine, technology and everyday life. Measuring devices provide precise measured values, often with a defined measurement uncertainty. Most measuring devices can and must be calibrated regularly to ensure that the results remain correct. The most important areas of application include industry and manufacturing, research and development as well as medicine and health.
Electrical measuring devices measure electrical quantities such as current, voltage, resistance, power, capacitance, inductance, etc. These devices include, for example, multimeters for measuring current, voltage and resistance as well as oscilloscopes (showing voltage curves over time), resistance meters and data loggers for electrical quantities that record voltage, current and energy consumption over a longer period of time. Electrical measuring devices often use measuring amplifiers to amplify weak signals. Examples include differential amplifiers for precise voltage measurement. They are often used in electronics, electrical engineering and energy technology to analyse and monitor electrical systems.
These devices measure physical quantities such as temperature, pressure, mass, length, time, speed, force, energy, etc. These include thermometers, barometers, scales, force gauges and data loggers. Physical measuring amplifiers amplify signals from strain gauges, force sensors or acceleration sensors. They are used in physics, engineering, meteorology and many other areas in which physical properties need to be analysed.
Both types of measuring devices are used to obtain precise data and to monitor and analyse processes or phenomena. Electrical measuring devices measure quantities within the electrical system, while physical measuring devices focus on physical properties outside the electrical context. Electrical measuring devices often require a power source, while physical measuring devices are often mechanical in nature. In practice, the categories often overlap, as physical quantities (e.g. temperature, pressure) can also be measured using electrical signals, for example by using sensors, data loggers and measuring amplifiers.

Data loggers are electronic devices that record physical or chemical measured variables (such as temperature, humidity, pressure, light, voltage, current, etc.) continuously or at specific intervals, store them and make them available for later analysis. They consist of sensors, a memory unit and often a software interface for analysing the data.
Data loggers record physical or chemical variables using special sensors, store the recorded values and enable them to be analysed later. The sensors measure the desired parameters, such as temperature, humidity or pressure, continuously or at specific time intervals. The collected data is saved in the device's internal memory or on external storage media such as an SD card. Many data loggers also have a real-time clock to precisely time the measurement results. The stored information can then be transferred to an end device via various interfaces - such as USB, WLAN or Bluetooth - and analysed and visualised using special software. This makes it possible, for example, to recognise trends, create diagrams and document reports.
Regular calibration of data loggers is necessary to ensure the accuracy and reliability of the measured data. Over time, the properties of the sensors can change due to ageing or external influences such as temperature fluctuations, mechanical stress or contamination, causing measurement deviations. Calibration is carried out by comparing the measured values of the data logger with a high-precision reference device. Possible deviations are detected and, if necessary, corrected by adjustment. Particularly in areas with high quality requirements or legal specifications - such as in industry, medicine or food monitoring - regular calibration is crucial in order to comply with standards such as ISO or FDA guidelines and to ensure reliable measurement results.
Measuring amplifiers are electronic components or devices that amplify weak electrical signals from sensors or measuring transducers in order to make them usable for further processing, display or storage. These amplifiers play a central role in measuring systems, as the signals from sensors are often very small and susceptible to interference. A measuring amplifier ensures that these signals are reliably recorded and converted into an amplified, low-interference form.
Measuring amplifiers take the weak output signals from a sensor or transducer, amplify them proportionally and prepare them for downstream devices or systems. They usually consist of precise operational amplifiers and electronic filters that amplify the signal and reduce interference signals (such as noise or interference). A differential amplifier is often used, which amplifies the difference between two inputs and eliminates interfering DC voltage components. The output of the measuring amplifier then provides an amplified signal that is passed on to a display, a data acquisition system or a control system, for example.
An important part of the function is the adaptation to different sensors and measuring ranges. Measuring amplifiers therefore often offer setting options to adjust amplification factors (gain) or offset corrections and to optimally amplify the signal.
The calibration of measuring amplifiers is necessary to ensure that they amplify signals correctly and with the desired precision. Ageing of the components, thermal influences or mechanical loads can lead to deviations in the amplification or zero point shifts that impair the measuring accuracy.
During calibration, the measuring amplifier is tested with a reference signal whose amplification factor is precisely known. The output signals of the measuring amplifier are compared with this reference value in order to detect deviations and adjust them if necessary. This regular check is particularly important in order to fulfil the requirements for accuracy and reliability in industrial and scientific applications.
Measuring amplifiers are used in numerous applications and industries, especially where small signals need to be precisely recorded and processed..
