Product Overview
The SUP RTX2400-G is an in-line gauge pressure transmitter in the RTX2000 series, developed for accurate and configurable pressure measurement in industrial process systems. Six pressure-range codes are available to cover different gauge-pressure requirements, from low-pressure measurement through upper range limits of 700 bar.
The transmitter combines two-wire 4-20 mA transmission with HART® 7 digital communication. An optional LCD display and local 3-button user interface allow on-site indication and configuration, while HART communication enables integration with compatible configuration and process-control systems.
The RTX2400-G can be configured with multiple process connections, wetted-material options, electrical connections, mounting brackets and two-valve manifold arrangements to suit different installation requirements.
