Mounting - Model 224 pressure transducers can be installed with Face Seal
Fittings or can be butt welded into place.
When installing units with Face Seal Fittings:
a.) Align piping system to transducer connections
b.) Hand tighten nuts
c.) Torque nuts by placing wrenches on nuts only (or on nut and wrench flats
of transducer body for units with fixed male face seals) Never hold the unit
by the electronics housing during installation.
NOTE: Welding purge gases are very hot! It is important to flow hot purge gases away from the
transducer. Disconnect all electrical connections to transducer when welding.

2.4 Venting
Model 224 transducers are vented through the electronics housing.
3.0 ELECTRICAL INSTALLATION
3.1 Voltage Output Units
The Model 224 voltage output transducer is supplied with a 6ft. multiconductor
cable, Bayonet style connector, Mini Din connector, or D-Sub style connectors.
The voltage output is either 5 VDC FSO or 10 VDC FSO. Diagram 1 shows electrical
connection wiring for voltage output transducers, and the excitation required.
Diagram 1
Note: Model 224 can be wired as a 3-wire device by connecting – OUTPUT and –EXCITATION and drain
wire to a common ground. However, accuracy may be reduced due to increase in resistance.
3.2 Current Output Units
The Model 224 is a two-wire loop-powered 4 to 20mA current output unit and
delivers rated current into any external load of 0-800 ohms. The Model 224 is
available with 6ft. of multiconductor cable, Bayonet, Mini Din, or D-Sub style
connectors. Diagram 2 shows electrical connection wiring for current output
transducers.
The power supply must be a DC voltage source with a voltage range between
10 VDC and 30 VDC measured between the + and - terminals. The unit is calibrated
at the factory with a 24 VDC loop supply voltage and a 250 ohm load.
Current must flow in one direction only - Please observe polarity. (See
Diagram 3.) We suggest that the cable shield Drain Wire be connected to the
system’s loop circuit ground for optimum electrical noise rejection. On transducers
with integral connectors (e.g., on Bayonet,D-sub, or MiniDin Connector types),
connection to transducer case ground can be achieved by connecting the cable
drain/shield wire to the mating cable-mounted connector shell (see Note 1).

4.0 CALIBRATION
The 224 transducer is factory calibrated to the specific input pressure range vs.
output voltage or current and should require no field adjustment. For absolute
pressure ranges, the zero can be adjusted with full vacuum applied to the
pressure port. For compound ranges, the zero should be adjusted with the unit
at atmospheric pressure and the output adjusted as noted in Diagrams 5 & 6 on
pages 5 & 6. Zero and span adjustments can be made by removing the zero and
span hole plugs and washers and adjusting the zero and span potentiometers.
Be certain to replace the zero and span hole plugs and washers after adjustments
are made.Hole plugs and washers are installed in potentiometer holes to keep
contaminants out of the unit.

4.1 Voltage Output Zero Adjustment
While monitoring the voltage between the positive output (+OUT) and common
(COM), and with the pressure port open to atmosphere, or with zero pressure
applied,the zero may be adjusted by turning the zero potentiometer screw.
For the 5 VDC Full Scale Output, the tolerance on zero and span settings is
±25mV. For the 10 VDC Full Scale Output, the tolerance on zero and span
settings is ±50mV. For absolute pressure ranges, the zero should be adjusted
with a full vacuum applied. See the chart below for nominal“installed”output at
atmospheric pressure for compound pressure ranges.

4.2 Voltage Output Span Adjustment
(Complete the zero adjustment before setting span.)
Span or full scale output adjustments should only be performed by using an
accurate pressure standard (electronic manometer, digital pressure gauge,etc.),
with at least comparable accuracy to the 224 transducer (±0.25% FS). With full
range pressure applied to the pressure port, the span may be adjusted by
turning the span potentiometer screw. The span (full scale) output is factory set
to within ±25mV for 5 VDC FSO or ±50mV for 0 to 10 VDC FSO.
4.3 Current Output Zero Adjustment
While monitoring the current output, and with the pressure port open to
atmosphere or with zero pressure applied, the zero may be adjusted by turning
the zero potentiometer screw. The factory setting is 4mA (±0.08mA). For absolute
pressure ranges, the zero should be adjusted with a full vacuum applied.
For compound pressure ranges, the zero should be adjusted with the unit at
atmospheric pressure and the output adjusted as noted in Diagram 6 below.
Note: When it is not possible to vent input pressure for zero adjustment (i.e., hazardous
gasses), zero may be adjusted by pulling a vacuum and setting the unit to 4.0 mA (±0.08
mA). This method may result in a small zero setting error due to variations in barometric
pressure.
4.4 Current Output Span Adjustment
Span or full scale output adjustments should only be performed by using an
accurate pressure standard (electronic manometer, digital pressure gauge, etc.)
with at least comparable accuracy to the 224 transducer (<0.25% FS). With full
range pressure applied to the pressure port, the span may be adjusted by turning
the span potentiometer screw. The span (full scale) output is factory set to within
±0.08mA.
