High-temperature processes need a transmitter that can withstand the heat while providing intelligent, multi-protocol communication. This intelligent pressure transmitter measures up to 0-100 MPa with HART, Foundation Fieldbus and PROFIBUS protocols, making it ready for modern smart-plant integration. With a CL150 (DN25) connection and multiple thread options, it delivers precise, digitally-connected pressure measurement for high-temperature process and utility applications.
The transmitter measures process pressure with a high-accuracy sensing element and converts it to a 4-20 mA signal with superimposed digital communication (HART, Foundation Fieldbus or PROFIBUS). The intelligent electronics provide advanced diagnostics, remote configuration and multi-variable data. The high-temperature design, with appropriate diaphragm materials and connection options, allows measurement in elevated-temperature process conditions.

Q: What is an intelligent pressure transmitter?
An intelligent pressure transmitter is a microprocessor-based instrument that provides digital communication, advanced diagnostics and remote configuration in addition to the standard 4-20 mA signal. Intelligent transmitters can report device status, perform self-diagnostics and be configured remotely, reducing maintenance effort and improving plant asset management.
Q: What protocols does it support?
It supports HART, Foundation Fieldbus (FF) and PROFIBUS protocols. HART overlays digital communication on the 4-20 mA loop, while FF and PROFIBUS are full digital fieldbus protocols. This multi-protocol support lets the transmitter integrate with a wide range of DCS and asset-management systems.
Q: What is the measurement range?
The measurement range is -0.1 to 0 to 100 MPa, covering a very wide span from slight vacuum to high pressure. This breadth allows one transmitter platform to serve many process, power and chemical applications with a single instrument design.
Q: Is it suitable for high temperature?
Yes, the transmitter is designed for high-temperature process measurement, with appropriate materials and connection options for elevated temperatures. The specific temperature limit depends on the configuration and materials, and for the highest temperatures a remote-seal or cooling-extension design may be specified.
Q: What power supply does it need?
It operates on a 24 V DC supply (with 5 V DC and 15-30 V DC options for certain configurations), the standard for industrial instrumentation. The low-voltage supply integrates with standard control panels and power systems.
Q: What process connections are available?
The transmitter offers a CL150 (DN25) flanged connection and threaded options including G1/2, G1/4 and M20×1.5. The choice depends on the vessel or pipe fitting and the process pressure and temperature.
Q: What pressure types are available?
It offers gauge, absolute and sealed gauge pressure types. Gauge references atmosphere, absolute references vacuum, and sealed gauge uses a fixed internal reference. The correct type is selected based on the application's reference requirements.
Q: What are the benefits of intelligent diagnostics?
Intelligent diagnostics continuously monitor the transmitter's health and can detect issues such as sensor drift, electronics faults or out-of-range conditions before they cause process problems. This enables predictive maintenance, reducing unplanned downtime and improving reliability.
Q: How does it integrate with a DCS?
The transmitter connects to a DCS either through its 4-20 mA analog signal with HART, or directly through Foundation Fieldbus or PROFIBUS digital networks. Digital fieldbus integration reduces wiring and provides richer data, while HART preserves compatibility with existing analog infrastructure.
Q: Where is it used?
It is used in high-temperature process reactors, power plant steam lines, high-pressure chemical processes and district heating systems. It provides intelligent, multi-protocol pressure measurement for demanding process and utility applications.
