Guide and selection support
Temperature probes are used in laboratory applications to accurately record temperature trends and provide digital or analog measurement values. They are utilized in various fields such as process monitoring and analytics. When selecting temperature probes, factors like measurement principle, medium (solid, liquid, gas), installation conditions, and calibratability are essential to find suitable sensors for specific laboratory requirements. LabFinder provides a clear overview of temperature probes, their variants, and applications, enabling users to quickly identify technically relevant products and suppliers for their measurement tasks.
Applications and Benefits
Temperature probes are used to detect and monitor temperature values in various media, including solids, liquids, and gases. They play a central role in analytics and process control, such as monitoring temperature parameters in reactions, incubation processes, or storage. The sensors record temperature changes and convert them into electrical signals that can be evaluated by measuring instruments or controllers.
Selection Criteria
The choice of temperature probes depends on the specific application and requirements for measurement accuracy, medium, and temperature range. Important factors include the measurement principle used (e.g., resistance thermometer Pt100 or thermocouple), design (immersion probe, surface probe, penetration probe), as well as size and protection class. The type of connection and compatibility with existing measuring devices are also crucial for procurement.
Variants and Measurement Principles
Temperature probes rely on different measurement principles. Classic types include resistance thermometers (Pt100, Pt1000), which operate on the temperature-dependent resistance of metals, and thermocouples, which generate thermoelectric voltages in relation to temperature. Besides analog probes, digital sensors are also common, providing direct digital output signals. Designs range from immersion to surface and penetration probes.
Calibration and Maintenance
For precise measurements, temperature probes should be calibrated regularly to detect and correct measurement deviations. Calibration is usually carried out in accredited laboratories or by comparison with reference sensors. Maintenance activities include checking cables, connections, and housings for damage as well as cleaning, especially when exposed to liquids or aggressive media.
Application Limits
The limits of use for temperature probes are determined by temperature range, chemical compatibility, and mechanical durability. Some probes are not suitable for very high temperatures or highly corrosive media. Extreme mechanical stress or vibration can also impair sensor function. Choosing the appropriate probe type considering these limitations is essential for reliable measurements.

Frequently asked questions
How does a temperature probe basically work?
A temperature probe measures temperature changes by altering its physical properties, such as electrical resistance or thermoelectric voltage, and converts these changes into signals that are detected by measuring instruments.
What types of temperature probes are used in laboratory settings?
Common types include resistance thermometers (e.g., Pt100), thermocouples, digital temperature sensors, and various designs such as immersion, surface, and penetration probes.
What should I consider when selecting a temperature probe?
Key criteria include the measurement principle, temperature range, medium and application condition, as well as compatibility with existing measurement systems and requirements for accuracy and response time.
How often should temperature probes be calibrated?
The calibration frequency depends on the application but is often recommended annually to ensure measurement accuracy and reliability.
What are the limitations of using temperature probes in the laboratory?
Temperature probes can be limited by excessively high temperatures, aggressive media, or mechanical stresses. Selecting the right sensor type is crucial to address these limitations.
