3.6.3
Measuring cell operation
In the following sections, the process variable to be measured is called general input
pressure.
Overview
The following modes of operation are described:
• Gauge pressure
• Absolute pressure
The following process connections are available, for example:
• G½
• ½-14 NPT
• Front-flush membrane:
SITRANS P300 with HART communication
Operating Instructions, 06/2005, A5E00359579-02
– F&B and pharma flange
– Bioconnect/Biocontrol
Caution
If the measurement signal fails because of sensor breakage, the seal diaphragm may
also be destroyed.
In the worst case, the process medium escapes at the process connection in devices for
gauge pressure with a span of ≤ 63 bar.
