Application range
Overview
The pressure transmitter is available in versions like gauge pressure, differential pressure
and absolute pressure. The output signal is a process-specific digital measured value. The
measured value is displayed with the associated status. The pressure transmitter measures
corrosive, non-corrosive and hazardous gases, vapors and liquids.
You can use them for the following measurement types:
•
Gauge pressure
•
Differential pressure
•
Absolute pressure from the gauge pressure breaker range
•
Absolute pressure from the differential pressure breaker range
With appropriate parameterization, you can also use it for the following additional
measurement types:
•
Level
•
Volume
•
Mass
•
Flow
You can install the transmitter of the appropriate version having the "intrinsically safe" type of
protection EEx ia, EEx ib or "flameproof enclosure" EEx d in hazardous areas, on zone 0
and in zones 1 or 2. Devices have an EC-type examination certificate and fulfill the
corresponding harmonized standards, e.g. European CENELEC.
Gauge pressure
This version measures the gauge pressure of corrosive, non-corrosive and hazardous
gases, vapors and liquids.
Differential pressure
This version measures:
•
Differential pressure
•
Positive or negative gauge pressure
•
A flow rate with q ∼
S
GLII
, together with a throttling device
It measures the pressure of corrosive, non-corrosive and hazardous gases, vapors and
liquids.
