Pressure transmitters are digital pressure transmitters featuring extensive user-friendliness and high accuracy. The
parameter assignment is performed using input buttons or the HART interface.
The comprehensive functionality makes for precise adjustment of the pressure transmitter to the requirements of the plant. Operation is very user-friendly in spite of the numerous setting options.
Due to their advanced diagnostic functionalities according to NAMUR NE107, the pressure transmitters are very
suitable for use in chemical plants. Thanks to the advanced diagnostic
functions and the process value storage, the is “Ready
for Digitalization”.
The “Remote Safety Handling” function saves customers significant
amounts of time and money, because the SIL function can be
switched on and validated remotely via SIMATIC PDM. This eliminates
travel times and on-site operation via the local display or keyboard.
Parameter assignment using the HART protocol is very easy and quick
thanks to the innovative EDD with integrated Quick Start wizard.
The transmitters can be equipped with various types of remote
seals for special applications such as the measurement of highly
viscous substances.
pressure transmitters are available in various
versions for measuring:
• Gauge pressure
• Absolute pressure
• Differential pressure
• Level
• Volume flow
• Mass flow
A Differential Pressure (DP) Transmitter measures the difference in pressure between two points and converts it into a standardized electrical signal (typically 4–20 mA, HART, Foundation Fieldbus, etc.).
