What is an immersion temperature sensor?
Immersion temperature sensors are primarily used to measure the temperature of liquids and solids. During use, if the probe temperature is lower than the actual object being measured, the principle of energy conservation dictates that heat energy will be transferred from the object to the probe. If the probe temperature is higher than the actual object being measured, heat energy will be transferred from the probe to the object being measured.
In this case, the object being measured will be heated, and the measured temperature will be the object’s temperature after heating. In this case, the probe-to-medium ratio must be considered. The better the probe-to-medium ratio, the more accurately the energy absorbed by the object can be measured, minimizing measurement errors.
It is important to understand that the temperature measured by the instrument is not the medium temperature, but the sensor temperature. Key ways to minimize measurement errors include ensuring the immersion depth is 10 to 15 times the probe diameter. When the medium being measured is a liquid, keep it as still as possible.
How to install an immersion temperature sensor?
Immersion installation is recommended for measuring liquid or gas temperatures.
The sensor probe is directly immersed in the liquid or gas, typically with a protective sleeve. This installation method is commonly used for measuring the temperature of liquids in liquid storage tanks, fluids in pipelines, gas pipelines, or gases in reactors.
Notes:
- The protective sheath material must be compatible with the medium (e.g., corrosion-resistant and high-temperature resistant).
- Ensure sufficient immersion depth to prevent the probe from being exposed to air.
- Regular inspection for protective sheath damage or blockage.
Which temperature sensor has the highest accuracy?
Based on Sino-Inst’s years of experience in temperature measurement, digital temperature sensors offer the highest accuracy. Sino-Inst’s temperature sensors are suitable for most operating conditions. The high accuracy of our temperature sensors is due to the following factors:
We improve the accuracy of our temperature sensors through temperature compensation, linearization, nonlinearity correction, and environmental interference suppression.
- Temperature compensation eliminates the effects of the sensor’s own temperature on measurement results. It ensures stable performance across various operating temperatures.
- Linearization creates a linear relationship between the sensor’s output signal and temperature, facilitating subsequent processing and calculations.
- Nonlinearity correction corrects for the inherent nonlinear characteristics of the sensor, further improving measurement accuracy.
- Environmental interference suppression technology can resist interference from external factors such as electromagnetic interference and thermal radiation on measurement results.
