Pneumatic Connections
Clean all pipelines to remove dirt and scale before instal-
lation.
Apply a minimum amount of pipe compound to the male
threads of the fitting only. Do Not use teflon tape as a
sealant. Start with the third thread back and work away
from the end of the fitting to avoid the possibility of
contaminating the transducer. Install the transducer in the
air line.
NOTES: Instrument quality air, per ISA Standards
D7.3-1981, is required. Use a filter to re-
move dirt and liquid in the air line ahead of
the transducer for correct performance. If
an air line lubricator is used, it MUST be
located downstream, beyond the trans-
ducer.
The user is responsible for insuring that the
environment in which the unit will be
installed, and the operating gas, are com-
patible with the materials in the trans-

Electric Connection
For the T5220 Transducer, make connections to theTermi-
nal Block through a 1/2 NPT Conduit Connector (not
supplied) and a plastic sleeve as shown below in Figure 7.
“Electrical Connections”.
For the TXPD5220Transducer, make connections from the
Sealed Connector Wires to an externalTerminal Block. The
TXPD5220 Transducer has an additional ground wire that is
used. For more information, see Figure 7. “Electrical
Connections” below.
NOTE: The T5220 & TXPD5220 should be wired in
accordance with the wiring diagram inside of
cover.
Wiring in Hazardous Areas
Wiring in hazardous areas should be performed in accor-
dance with the Table 1. and any local codes that apply.

CALIBRATIONS / ADJUSTMENTS
Equipment Required for Calibration:
• Pneumatic Supply capable of delivering up to 150 psig.
• Current Supply capable of delivering up to 50 mA.
• Voltage Supply capable of delivering up to 10 VDC.
• Pressure Gage capable of a digital readout up to 50 psig
with an accuracy of .1%.
• Digital Volt Meter capable of a readout up to 30 mA or
10 VDC with an accuracy of .02%.
The following adjustments are provided:
Full Range Operation
Forward/Reverse Mode
Calibration - Zero and Span
FULL RANGE OPERATION
Forward Acting Mode Adjustment
NOTE: Air Supply must be on before adjustments are
made.
1. Connect the input signal to the transducer as shown
in Figure 6. “Electrical Connections.”
• Forward Acting Calibration-Zero
2. Apply the minimum input signal and adjust the Zero
screw for minimum output pressure. Turn screw
counterclockwise to increase pressure and clock-
wise to decrease pressure.
• Forward Acting Calibration-Span
3. Apply the maximum input signal and adjust the Span
screw on the potentiometer for maximum output
pressure. Turn screw clockwise to increase pres-
sure and counterclockwise to decrease pressure.
4. Repeat steps 2-3 until the desired output range is
obtained. For more information, see Figure 7. “T5220/
TXPD5220Calibration Configuration.”
Reverse Acting Mode Adjustment
NOTE: Intrinsically safe units cannot be set for re-
verse acting mode in field.
5. Connect the input signal to the transducer as shown
in Figure 6. “Electrical Connections.”
• Reverse Acting Calibration-Zero
6. Apply the minimum input signal and adjust the Zero
screw for maximum output pressure. Turn screw
counterclockwise to increase pressure and clock-
wise to decrease pressure.
• Reverse Acting Calibration-Span
7. Apply the maximum input signal and adjust the Span
screw on the potentiometer for minimum output pres-
sure. Turn screw counterclockwise to increase pres-
sure and clockwise to decrease pressure.
8. Repeat steps 6-7 until the desired output range is
obtained. For more information, see Figure 8. “T5200/
TXPD5200 Calibration Configuration.”
