How to Evaluate Submersible Pressure Transducers?

August 07, 2020

Modern industrial transducers are usually developed based on the measurement principles of submersible pressure transducers and traditional pressure transducers. If you think about it, if you don't have an submersible pressure transducer, where does the idea for non-contact sensors and wireless sensors come from? If the medium of various working conditions are not considered, how to develop different sensors according to different medium? If we do not understand the principle of static pressure measurement, how can we know the importance of submersible pressure transducers?

To sum up, I think the research and development of the submersible pressure transducer points out the direction for the design of the new sensor. Starting from his basic theory, investment type pressure sensor is a kind of measuring the pressure of level sensor, based on the static pressure of the measured medium and medium height proportional principle, and the spread of the silicon core body for pressure sensor with high precision, thus static pressure can be converted to electrical signals, after temperature compensation function and linear correction, and finally into a standard electrical signals (such as: 4-20 ma).

From the above analysis, we know that the submersible pressure transducer must be used for static water level measurement. At the same time, it also tells us from the side that whether the submersible pressure transducer, static pressure level sensor or submersible level sensor, they are all used for level measurement. If an submersible pressure sensor must be used to measure the dynamic water, this can be done by fixing the sensor or adding a bypass pipe, but it must be done within a small range.
