Key points for selection of diffused silicon pressure transmitter-1

- Sep 16, 2020-

The diffused silicon pressure transmitter for industrial applications mainly includes three parts: pressure sensor, measuring circuit and process connection. It can convert the physical pressure parameters of gas, liquid, etc., felt by the sensor into standard electrical signals, which can be supplied to the secondary instruments of industrial automation equipment, petroleum, chemical, metallurgy, power and other control platforms for measurement, indication and process adjust. The selection should be done before specific applications. Compared with other capacitive pressure transmitters, what special attention should be paid to the selection of diffused silicon pressure transmitters UPB13?

First of all, like other pressure transmitters, we must first understand what kind of pressure to measure, the measured medium and the application industry. First determine the max value of the measured pressure in the system. Generally speaking, you need to select a transmitter with a pressure range that is about 1.5 times larger than the max value; second is the physical and chemical properties and state of the measured medium, such as strong acid, strong alkali, viscous, easy solidification and crystallization, and gasification, the general diffused silicon pressure transmitter can measure the air pressure, oil pressure, and hydraulic pressure. However, because the diffused silicon core is made of 316L stainless steel, for gases that can corrode stainless steel, viscous media and media that are easy to crystallize cannot be measured. If it is the food, medicine, and health industries, you need to select a flat membrane pressure transmitter UPB2. Diffused silicon pressure transmitter with 2088 housing can be used outdoors.

The second is the temperature range. The diffused silicon pressure core has a fixed temperature resistance range. If it exceeds this range, measures need to be taken to choose a pressure tube or add a heat sink to reduce the temperature of the pressure transmitter UPB8.
