KELLER 20SX – Piezoresistive Pressure Transmitter Heads With the Highest Level of Accuracy

The KELLER 20SX series pressure transmitter heads with thread connection were specially designed and optimised 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 minimised 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
