According to the different pressure sensing components, the pressure transmitter can be divided into metal pressure transmitter, ceramic pressure transmitter, diffusion silicon pressure transmitter, monocrystalline silicon pressure transmitter, sapphire pressure transmitter, sputtered film pressure transmitter, etc. Metal pressure transmitters have poor accuracy, ceramic pressure sensors are greatly affected by temperature, and monocrystalline silicon pressure transmitters are expensive. Let’s take a look at the main features of the most widely used diffusion silicon pressure transmitters.
The diffusion silicon pressure transmitter is highly accurate and needs to be temperature compensated. At room temperature, the sensitivity coefficient of the diffusion silicon pressure transmitter is 5 times that of ceramic, with high accuracy and fast response speed.
As a high-performance primary pressure transmitter measurement product, it can be easily amplified and assembled into a standard signal output device, and the diffusion silicon pressure transmitter is widely used in pressure process control in petroleum, chemical, metallurgy, electric power, aviation, medical equipment, automotive, HVAC and other industries.
In the process of using the diffusion silicon pressure transmitter, we need to pay attention to the fact that the core sensing side of the diffusion silicon pressure transmitter is not allowed to be touched by fingers or subjected to impact, otherwise in addition to the linearity will be destroyed, it will also cause permanent failure.
Diffusion silicon pressure transmitters have excellent performance. It has strong anti-interference, overload and impact resistance, small temperature drift, high stability, and high measurement accuracy, making it an ideal pressure measuring instrument in the field of industrial automation.
