Precont® TM

Delivery Time: not specified

With capacitive ceramic measuring cell for rugged industrial use

  • Highly accurate and long-term stable ceramic measuring elements
  • Mechanically massive design
  • Overvoltage protection

 

Description

The Precont® TM is a very rugged overload resistive pressure transmitter for gases, steams, liquids and dusts in hard industrial applications. By use of a dry capacitive ceramic measurement sensor in combination with high-grade steel 1.4571 (V4A), this pressure transmitter can be also used in very aggressive substances. The ceramic membrane has also an extreme overload resistance, highest measurement precision, long life time and no need for maintenance.
