Description
The 23SX series pressure sensors were developed for industrial applications where special requirements for measurement accuracy and stability are demanded.
In this series, temperature dependence and nonlinearity are compensated with high precision thanks to the mathematical model embedded in the sensor electronics. In addition to the RS485 interface with Modbus RTU protocol, this device offers an option for outputting a scalable analog signal via a built-in digital-to-analog converter. The fully welded design without internal seals is suitable for applications with dynamic pressure. Only stainless steel is in contact with the measured medium.
Features
- RS485 interface possible together with analog interface
- Analog interface can be reconfigured or disabled via RS485 interface
- Modbus RTU protocol for measurements, configuration, zero and span adjustment
- Excellent long-term stability
