PC11-BQ Fully Welded Pressure Sensor
Product overview
The PC11-BQ pressure sensor has provided customers with four designs, and it has successfully provided over a hundred customers with such a solution: welding the pressure core body and interface pressure head together, fundamentally eliminating the problem of "O" ring sealing leakage. It has high reliability, and is compact in size, making it the best choice for making highly reliable and high-quality pressure and liquid level transmitters. In order to provide a clearer description of this model of product, the information clearly defines which designs cannot be changed and which personalized designs are made by customers based on their actual needs. By integrating the advantages of Wotian with the needs of your company, a perfect product is formed.
