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, extraordinary long-term stability and an equally high proof pressure can be achieved. Features that many pressure transmitter manufacturers offer only as optional extras come as standard with KELLER products. Along with a compact, fully welded design, the 20SX series also boasts highly precise and scaleable 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 now 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 scaleable by RS485 interface (turn-down)
- Modbus RTU protocol for process values and configuration
- Optimum long-term stability
