The Pressure Indicator Transmitter with Capillary is designed for accurate pressure measurement in high-temperature or inaccessible locations. It uses a remote diaphragm seal connected via a capillary filled with transmission fluid to isolate the sensing element from the process. The system provides local indication along with a 4–20 mA output for remote monitoring. It ensures reliable performance, minimizes process contamination, and is ideal for viscous, corrosive, or high-temperature applications.
