The XC-3D55 3-D Flow Measurement console is factory-configured for 120VAC/60Hz and
240VAC/50Hz electrical power. The Electrical Schematic for the console is presented on page 5.
A front panel-mounted circuit breaker rocker switch activates the Main Power and power supply. The
power supply energizes the velocity pressure and pitch differential pressure transducers, the
inclinometer (yaw measurement device) and the temperature display.
A 4-pin amphenol-style circular connector is mounted on the side of the console is used to provide
power to and signal from the remote inclinometer sensor. The standard size, female, Type K Stack
Temperature thermocouple jack is also mounted on the side of the console.
Output signals are included for the Stack Thermocouple, Velocity Pressure, Yaw Angle and Pitch
Angle. All signals are direct current, voltage-based. The specific outputs are listed on the electrical
schematic and in the specifications listed in Table 2.
Process meters are utilized to convert the direct current voltage (VDC) output pulses from the various
sensors into appropriate engineering units, such as inches/millimeters of water or degrees of rotation,
etc. The process meters display the P1-P2 velocity pressure and the P3-P4 pitch angle pressure. The
standard units of measurement are English units in “ H
2
O and
°
Fahrenheit. Metric units will be
displayed in mm H
2
O and
°
Celsius are available. The Yaw Angle is displayed via a high resolution
indicator where 1 pulse equals 0.1
°
.
The process meters, transducers and counter have been setup and calibrated at Apex
Instruments utilizing appropriate standards. Read this Operators Manual before making any
adjustments to the process meters, transducers or inclinometer.
