In-Line 3051T Diaphragm Seal Pressure Transmitter
Product introduction:
The Rosemount™ 3051T Diaphragm Seal Pressure Transmitter is a high-accuracy device designed for reliable gauge and absolute pressure measurements in challenging environments. When paired with a diaphragm seal system, it safely isolates the sensor from corrosive, high-temperature, or viscous process media, maintaining excellent performance and long-term stability. It offers multiple output protocols, a wide pressure range of up to 10,000 psi, and is ideal for industries like chemical, oil & gas, and food processing where sensor protection and precise measurement are critical.
