Applications:
Packing:
The 3051CG measures gauge pressure using a sealed reference, making it ideal for closed systems like steam lines or pressurized vessels.
It offers a standard accuracy of ±0.075% of span, with optional enhanced accuracy depending on configuration.
The transmitter supports 4–20 mA HART, FOUNDATION Fieldbus, and WirelessHART protocols for flexible integration.
Yes. It is available with ATEX, IECEx, FM, and CSA certifications for use in hazardous areas, including explosion-proof and intrinsically safe installations.
Depending on the sensor range, the 3051CG can handle up to 2000 psig (137.9 bar). Always verify with the model’s datasheet for specific limits.
Factory calibration is provided, but field calibration is recommended for optimal accuracy, especially in critical applications.
It supports Coplanar™ flange, traditional flange, and inline mounting, offering flexibility for integration into existing systems.
It provides ±0.2% URL stability over 10 years, reducing maintenance and recalibration needs.
Yes, but only with Rosemount-approved spare parts to maintain pressure integrity and safety compliance.
Absolutely. The 3051CG can be paired with Rosemount 1199 diaphragm seal systems for harsh or sanitary process conditions.
