High precision diffused silicon pressure sensor

Model: WCPS300-U73 series
  • Product Introduction

The WCPS300-U73 series high-precision diffused silicon pressure sensor/transmitter adopts an integrated pressure chamber without leakage, with room temperature accuracy better than 0.25% FS and up to 0.1% FS. The output mode is 4~20mA/0.5~4.5V~5V/0~10V/RS485 and other options are available. This sensor adopts a unique filtering algorithm and temperature compensation algorithm, compensating for temperatures of -20~85 ° C, and has the advantages of high accuracy, stability, and reliability.
 
The WCPS300-U73 series high-precision pressure sensor/transmitter is widely used in military/aerospace test benches, automotive test benches, calibration equipment, high-precision applications, fixed motor fuel control, high-end industrial machinery and other fields. It not only improves safety and energy efficiency, but also realizes automation and data-driven management, providing enterprises with more efficient, safe and sustainable security solutions.
