1.5 Purpose
Overview
Depending on the version, a transmitter measures corrosive, non-corrosive and hazardous
gases, vapors and liquids.
You can use the transmitter for the following types of measurement:
● Gauge pressure
● Absolute pressure
● Differential pressure
With appropriate parameter settings and the necessary add-on parts (e.g. flow orifices and
remote seals), the pressure transmitter can also be used for the following measurements:
● Level
● Volume
● Mass
● Volume of flow
● Mass flow rate
The output signal is always a load-independent direct current between 4 and 20 mA.
You can install the "intrinsically-safe" or "explosion-proof" version of the transmitter in
hazardous areas. The devices have an EC type examination certificate and comply with the
appropriate harmonized European CENELEC directives.
Transmitters with remote seals of different shapes can be delivered for special applications.
For example, measuring high-viscosity substances is a special application.
