The KELLER 20SX series pressure transmitter heads with thread connection were specially designed and optimized for OEM applications. The pressure transmitter head is a hybrid of the 20S pressure transmitter and KELLER X-line electronics. This combination means the highest level of accuracy, long-term stability, and an equally high proof pressure can be achieved.
Along with a compact, fully welded design, the 20SX series boasts highly precise and scalable digital compensation electronics. Unwanted inaccuracies, including thermal inaccuracies, can be minimized or compensated for using a mathematical model. The result is maximum accuracy and an extremely narrow TEB (total error band).
With the 20SX series, KELLER is offering a further design in the OEM product range for the industrial, oil, and gas sectors.
The KELLER 20SX series offers the following features:
- RS485 interface can be combined with analog interface
- Analog interface scalable by RS485 interface (turn-down)
- Modbus RTU protocol for process values and configuration
- Optimum long-term stability
