Machine thermometers
For precise measurement of temperature in industrial environments, machine thermometers are the traditional solution. Thermometers in this category operate on the expansion principle and allow you to accurately read the prevailing temperature on an analog scale.
Machine thermometers have been established for generations in the temperature measurement and control of various machines and equipment. Due to their effortless installation and simple way of reading, they can be attached to various machines with their sensors. They are suitable for basic measurement of temperatures in liquids and gases. The graduation of the scale depends on the temperature and is usually in one-, two- or five-degree increments. They are therefore not suitable for measurements in the tenths or hundredths range. In addition to the industrial sector, this measurement technology is also used for classic heating systems. The principle of representing temperatures by the expansion of liquids is also used in mobile glass thermometers. In addition to fixed mounting on a machine or plant, free measurements are thus also possible in any application areas.

A machine thermometer is an indispensable instrument in many industrial applications where accurate temperature measurements are required. It consists of a thermometer that has been specially developed for use in machines. The machine thermometer is usually equipped with a robust protective cover that protects it from damage and environmental influences. This means it can also be used in extreme environments such as near machines with high heat or vibrations. The accuracy of a machine thermometer is of crucial importance, as even minor deviations in temperature measurement can have serious consequences. For this reason, machine thermometers are regularly calibrated to ensure that they deliver precise results. Another advantage of machine thermometers is their versatility. They can be used for various applications, such as in the food industry, in the chemical industry or in metal processing. There are also special machine thermometers that are suitable for use in potentially explosive atmospheres, making machine thermometers indispensable tools for accurate temperature measurement in industrial environments. They offer precision, robustness and versatility and help to ensure quality and safety in various industries.
What is a machine thermometer and what is it used for?
A machine thermometer is an instrument used to measure the temperature of machines or other mechanical equipment. It consists of a thermometer, which is usually protected by a metal sleeve to protect it from damage. The metal sleeve is inserted into the machine to be measured in order to record the temperature directly at the point where the measurement is required.
Machine thermometers are used in various branches of industry, particularly in the mechanical engineering, automotive and aviation industries. They are used to monitor the temperature of machines or mechanical systems to ensure that they operate within certain limits. Overheating or overcooling can cause damage to the machines, so it is important to keep an eye on temperatures and take measures to regulate the temperature if necessary. Machine thermometers can also be used to monitor the efficiency of machines, as certain temperatures can indicate potential problems or wear.

How does a machine thermometer work and how accurate is it?
A machine thermometer is a device that is used to measure the temperature of machines or industrial processes. It consists of a temperature sensor probe, a display unit and, if necessary, a connection unit.
The temperature sensor probe is attached to the machine or process and takes the temperature measurements. There are different types of sensors, such as resistance thermometers or thermocouples, which are selected depending on the application and accuracy requirements.
The measured temperature data is then transmitted to the display unit, which displays the temperature values in digital or analog form. The display device can also offer functions such as saving measured values, monitoring temperature limit values or displaying trends and diagrams.
The accuracy of a machine thermometer depends on various factors, such as the quality of the temperature sensor, the calibration of the device and the environmental influences. High-quality machine thermometers can achieve an accuracy of a few degrees Celsius or even better.
It is important to note that accuracy may decrease over time, especially if the device is not regularly calibrated or maintained. It is therefore advisable to carry out regular calibrations to ensure that the machine thermometer provides reliable measurement results.

What types of machine thermometers are there and what are the differences between them?
There are various types of machine thermometers, including:
1. Bimetal thermometer: This type of thermometer consists of two metals with different expansion coefficients that are bonded together. When the temperature changes, the different expansion of the metals causes the bimetal to bend, allowing the temperature to be measured.
2. Gas-filled thermometers: These thermometers use a gas, usually mercury or alcohol, which expands as the temperature rises. The expansion of the gas is then used to measure the temperature.
3. Resistance thermometer: This type of thermometer is based on the principle that the electrical resistance of a metal changes with increasing temperature. The best known and most commonly used resistance thermometer is the platinum resistance thermometer (PT100), which measures the resistance of platinum.
4. Thermocouples: Thermocouples consist of two different metals that are joined together at one end. When the temperature at the connection points changes, an electrical voltage is generated that is proportional to the temperature difference. This voltage is then measured and converted into a temperature.
The main differences between the various types of machine thermometers lie in their accuracy, measuring range, response time, stability and areas of application. Bimetal thermometers, for example, are generally less accurate than resistance thermometers, but have a wider measuring range. Gas-filled thermometers are generally inexpensive, but can be inaccurate in certain environments due to the expansion of the gas. Resistance thermometers are very accurate and stable, but they usually have a limited measuring range. Thermocouples have a large measuring range and are also suitable for use in harsh environments, but have a lower accuracy compared to other types. Therefore, the choice of the right machine thermometer depends on the specific requirements and conditions of the application.

How are machine thermometers calibrated and how often should this be done?
Machine thermometers are usually calibrated by comparison with a reference thermometer. Both thermometers are placed in a measuring medium, such as water or oil, and brought to a certain temperature. The measured values from both thermometers are then compared and any deviations corrected.
Calibration of machine thermometers should be carried out regularly to ensure that temperature measurements are accurate and reliable. The exact intervals for calibration may vary depending on the specific requirements and regulations of the respective industry or application. In some cases, annual calibration may be sufficient, while in other industries more frequent calibration may be required, for example every six months or even monthly. It is important to follow the manufacturer's recommendations and, if necessary, consult with a specialist to determine the correct calibration intervals.
