Rosemount Pressure Transmitter 2051

Detailed Product Description

Confidence in your measurement
The 2051 capabilities are designed to meet a wide
range of applications. Combining 0.075% reference
accuracy, 100:1 rangedown, and extended two-year
stability provides confidence in your pressure
measurements.
Output protocols enable easy integration
The 2051 is available in 4-20mA HART, Low Power
HART, or FOUNDATION fieldbus output protocols.
Easily integrate the 2051 into existing or new
installations.
Coplanar platform enables integrated
solutions
The versatile Coplanar platform design enables the
best process connection for pressure, flow, and level
applications. The final 2051 assembly arrives factory
calibrated, pressure-tested, and ready to install. The
flexible design reduces engineering and inventory
costs.
Complete pressure offering
The 2051 family of pressure transmitters offers
differential, gage, and absolute pressure
measurements. The complete offering ensures the
2051 meets your measurement needs.
