The pressure transmitter PASCAL CV is suited for measuring the relative and absolute pressures of gases, vapors and liquids. The type series CV3110 has been developed to meet the stringent demands of food processing, pharmaceutical technology, and biotechnology. Special attention has been given to good surface quality. Thus, for instance, roughness values to Ra 0.4 µm can be guaranteed for wetted parts (for welds: Ra < 0.8µm) or the system can be electropolished as well.
The modular design of the pressure transmitter allows users to choose the best possible device for his specific operating requirements.
PASCAL CV is equipped with a variety of process connections and uses smart module technology for display, switching and communication purposes.These functional modules can be exchanged or extended with ease without having to remove the transmitter from the process.Other designs available
●PASCAL CV 3100 for general application
●PASCAL CV 3120 for chemical/petrochemical industry
