Meeting Your Pressure Measurement Needs
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.

Failure Mode Alarm
2051C Process Wetted Parts
If self-diagnostics detect a sensor or microprocessor failure, the
analog signal is driven either high or low to alert the user. High or
low failure mode is user-selectable with a jumper on the
transmitter. The values to which the transmitter drives its output in
failure mode depend on whether it is factory-configured to
standard or NAMUR-compliant operation. The values for each are
