Introduction

2.4 Document history

With the appropriate configuration and the necessary add-on parts (e.g. limiters and remote
seals), you can also use the pressure transmitter for the following measuring tasks:
• Level
• Volume flow
• Mass flow
• Volume
• Customized characteristic curve
The output signal for all measuring tasks is a direct current of 4 to 20 mA or a process-based,
digital signal (e.g. with PROFIBUS PA).
You can install the "intrinsically-safe" or "flameproof enclosure" version of the pressure
transmitter in hazardous areas. The devices have a test certification and comply with the
corresponding directives.
Pressure transmitters with remote seals of various shapes can be provided for special
applications. For example, measuring high-viscosity substances is a special application.
Operate the device in accordance with the specifications in section Technical data (Page 63).
