The output signal is a process-based, digital PROFIBUS PA/FOUNDATION™ Fieldbus FF
signal.
You can install the transmitter with the type of protection "Intrinsic safety" or "Flameproof
enclosure" in hazardous areas. The devices have an EC-Type Examination Certificate, and
comply with the corresponding harmonized European directives of the CENELEC.
The transmitter is available with various designs of remote seal for special applications. A
special application, for example, is the measurement of highly viscous materials.
Gauge pressure
This version measures the gauge pressure of corrosive, non-corrosive and toxic gases,
vapors and liquids.
The smallest measuring range is 1 bar g (14.5 psi g), the largest is 700 bar g (10153 psi g).
Absolute pressure
This version measures the absolute pressure of corrosive, non-corrosive and toxic gases,
vapors and liquids.
There are two series: A "Differential pressure" series and a "Gauge pressure" series. The
"Differential pressure" series features a high overload capacity.
The smallest measuring range of the "Differential pressure" series is 250 mbar a (3.63 psi a),
the largest is 100 bar a (1450 psi a).
The smallest measuring range of the "Gauge pressure" series is 250 mbar a (3.63 psi a), the
largest is 30 bar a (435 psi a).
Differential pressure and flow rate
This version measures corrosive, non-corrosive and toxic gases, vapors and liquids. You can
use it for the following types of measurement:
● Differential pressure
● Gauge pressure, suitable for small positive or negative pressure value
● In combination with a primary element: flow rate q ~
The smallest measuring range is 20 mbar (8.03 inH
2
O), the largest is 30 bar (435 psi).
