Monocrystalline silicon pressure transmitter vs diffused silicon pressure transmitter
Monocrystalline silicon and diffused silicon pressure transmitters are the two mainstreams in the field of pressure measurement. It is favored by more and more enterprises and engineers. Next let’s take a look at their differences.
1. Sensing components
The sensing element of the monocrystalline silicon pressure transmitter is a monocrystalline silicon wafer, which is made by micromachining technology. Monocrystalline silicon wafers have good mechanical properties and stability. Able to withstand high pressure and temperature changes. And has high accuracy and sensitivity.
The sensing element of the diffused silicon pressure transmitter is a resistance strain gauge formed by diffusion doping on the silicon wafer. Diffused silicon technology is relatively simple and low cost. However, its stability under high temperatures and harsh environments may not be as good as that of monocrystalline silicon.
2. Performance characteristics
Accuracy and stability are important indicators of pressure transmitters.
Monocrystalline silicon pressure transmitters generally have higher accuracy and better stability, providing more accurate measurements. It maintains good performance over a wide range of temperatures and pressures.
Diffused silicon pressure transmitters are relatively more economical, but their performance may be affected under certain extreme conditions. For general industrial applications, diffused silicon pressure transmitters still meet most needs.
3. Application occasions
Due to the high accuracy and stability of monocrystalline silicon pressure transmitters, they are widely used in fields with strict measurement requirements, such as aerospace, petrochemical, semiconductor and other industries.
Diffused silicon pressure transmitters are more suitable for some general industrial measurement occasions, such as process control, machinery manufacturing, etc. Its cost advantage makes it attractive in some price-sensitive projects.
4. Price factors
The manufacturing cost of monocrystalline silicon pressure transmitter is relatively high, so the price is also relatively expensive. However, in applications where accuracy and reliability are critical. The performance advantages often offset some of the price difference.
Diffused silicon pressure transmitters generally have a lower price. Making it a viable option if you are on a tight budget.
5. Installation and maintenance
There are no significant differences in installation and maintenance between the two pressure transmitters. However, monocrystalline silicon pressure transmitters may require more careful handling and protection. to ensure that its accuracy and stability are not affected.
In short, when selecting a pressure transmitter, comprehensive considerations should be made based on specific application requirements, budget, and working environment. For some critical applications, such as areas involving safety and precise control. Monocrystalline silicon pressure transmitters may be a better choice. In some general industrial scenarios, diffused silicon pressure transmitters can provide cost-effective solutions.
How accurate are pressure transducers?
Accuracy refers to the error between the pressure transmitter output signal and the actual pressure value. Usually expressed as a percentage or absolute value, such as 0.5%FS, 1%FS, etc. FS refers to the full scale, which is the maximum pressure value that the pressure transmitter can measure.
Generally speaking, the accuracy of our commonly used pressure transmitters is 0.5%FS. The accuracy of high-precision pressure transmitters is 0.1%FS, 0.075%FS.
Which transducer is used for high pressure measurement?
Different types of pressure transmitters have different upper pressure limits that can be measured. The measurement upper limit of our conventional pressure transmitter is 100MPa, or 160MPa. If you need to measure a higher pressure range, such as 300MPa, 700MPa, etc., then you can use Sino-Inst’s customized high-pressure pressure transmitter.
