Emerson FB2200 Flow Computer Temperature Input (RTD/PRT)

Temperature Input (RTD/PRT)

With industry-leading measurement accuracy, the

temperature measurement of the FB2200 ensures that

you minimize your measurement uncertainty in all

operating conditions. The input accepts 2-, 3-, or 4-wire

connections reducing any field wiring induced errors

and also supports sensor curve matching using the

optional Callendar-Van Dusen constants to define the

unique characteristics of the RTD/PRT to further

improve process temperature measurement uncertainty.

The FB2200 flow computer’s superior static pressure,

DP, and temperature measurement performance and

stability ensures you meet standards and regulations

so you can avoid fines, penalties, leaseholder disputes,

and lost revenue.

Inputs and Outputs

Base I/O

In addition to the integral pressure sensor, the FB2200

includes the following I/O points in the base unit:

▪ Two analog channels – individually software

selectable analog inputs (AI) or analog outputs (AO)

▪ Two discrete channels – individually software

selectable discrete inputs (DI), discrete outputs

(DO), or pulse inputs (PI)

▪ One RTD/PRT (2-, 3-, or 4-wire)

Analog Inputs (AI) are individually software

configurable for either 4 to 20mA or 1 to 5 Vdc

operation.

To keep measurement uncertainty at a minimum when

external transmitters are being used, both the AI and

AO channels have industry-leading measurement

accuracy with an excellent performance over a wide

ambient temperature range.

Each Discrete Input (DI) channel can also be software

configured to function as a latched DI.

The Discrete Output (DO) channels are solid-state,

normally open switches rated at 500 mA, enough to

directly drive most samplers. Each DO channel can be

software configured as a latched, toggled, momentary,

timed duration output (TDO), or scaled pulse output.

The PI channels are most commonly used to interface

with turbine meters, Coriolis meters, ultrasonic meters,

and Positive Displacement (PD) meters. The high

speed input supports signal up to 10.5 KHz.
