Benefits of Agent Brand Include
- The compact design of these transmitters help with their easy connection to the process unit, which also eases the installation process.
- The two-wire 4-20 mA transmitter offers the user the option to choose the type of output— linear or square root.
- They come with advanced diagnostic features which help detect critical issues, and on-scale failures due to loop issues.
- These transmitters are capable of measuring multiple types of pressures upon adjusting their configuration, such as differential, gauge, and absolute pressure.
- Their construction material could be Hastelloy or 316L stainless steel for sensor wetted parts, while the process flange could be made of either carbon steel or stainless steel.
- They come with a remote display and interface, which makes it easy to access useful process-related information from the device.
- They help minimize shock, vibration, and temperature fluctuations, and are designed to work in harsh environments.


- Patented Rosemount Coplanar technology offers optimized performance as a pressure, Differential Pressure Flow or Differential Pressure Level solution.
- Application specific configuration allows you to transform your pressure transmitter into a flow meter with a totalizer or a level transmitter with volume calculations.
- Complete pressure, level, or flow assemblies are leak-tested and calibrated to reduce leak points up to 70% and simplify installation.
- 10-year installed stability and 150:1 rangedown produce reliable measurements and wide application flexibility.
- Bluetooth® wireless connectivity unlocks a far simpler process to perform maintenance and service tasks without the need for a physical connection or separate configuration tool.
- The graphical, back-lit display allows for easy operation in 8 different languages in all lighting conditions.
- Loop Integrity and Plugged Impulse Line diagnostics detect electrical loop issues and plugged impulse piping before it impacts the quality of the process for increased safety and reduced downtime.
- Quick service buttons offer built-in configuration buttons for streamlined commissioning.
