The Series 2900 Current to Pressure Transducer delivers reliable
high performance for the toughest applications in the most hazardous
environments. Its NEMA 4X housing is designed and FM and CSA
approved for both intrinsically safe and explosion-proof operation. This
unit has advanced circuitry which includes electronic feedback control
for superior vibration protection and highly accurate output. The Series
2900 is not position sensitive and the easily accessible zero and span
adjustments make field calibration quick and easy. For ease of
installation, this model has input and output ports on both the front and
back. It is also not vibration sensitive, which makes the Series 2900 ideal
for field mounting on a valve. These features coupled with the unit’s
compact size help make set-up and installation simple.

t
Mounting
The Series 2900 has been designed to mount inline, to a standard valve
yoke with the A-180 valve mounting kit.
Pneumatic Connections
Clean all pipe lines to remove dirt and scale prior to installation. Supply
air must be filtered to 40 microns and free of moisture and lubricants.
Two 1/4˝ NPT ports are provided for supply air connections. Either port

OPERATION
Calibration
All units are shipped from the factory calibrated, direct acting. If the user
requires a different mode of operation (i.e. reverse acting, split range) it
is necessary to reposition internal electrical dip switches located on the
circuit board (see Figure 1) as indicated in Figure 3.
Though the units are factory calibrated for direct acting operation, it is
suggested that the user check the calibration to ensure that settings and
operation match the application requirements.

NOTICE
It is not necessary to remove the plastic cover of the unit for
calibration if the Direct Acting mode is desired.
Direct Acting Calibration
In direct acting operation the unit is calibrated so that minimum input
signal corresponds to minimum output pressure and increasing input
signal results in increasing output pressure.
Apply the minimum input signal of the range being used (e.g. 4 mA).
Observe the output pressure. If necessary, adjust the zero screw until
reaching minimum output pressure setting. Turn zero screw clockwise to
decrease and counter-clockwise to increase.
Apply the maximum input signal of the range being used (e.g. 20 mA).
Observe the output pressure. If necessary, adjust the span screw until
reaching maximum output pressure setting. After setting the span it will
be necessary to recheck the zero. Repeat steps until both end points are
at required values.
Reverse Acting Calibration
When calibrating to operate in the reverse acting mode the minimum
input signal produces the maximum output pressure and increasing the
input signal results in decreasing the output pressure. Setting the unit to
operate in the reverse acting mode is accomplished by positioning
internal electrical dip switches located on the circuit board (see Figure
1).
WARNING
Transducer fails in direct mode regardless of operating mode selected.
Do not touch any components on circuit board except dip
switches. Do not reverse the input leads. Damage may occur.
Access circuit board by first removing the die cast cover of the unit. Then
remove plastic cover by taking out two screws. Position the dip switches
as illustrated in Figure 4. Set the input signal to the minimum value being
used. Turn the zero screw to set the maximum output pressure. Turn
screw clockwise to decrease and counter-clockwise to increase. Set the
span by applying the maximum input signal. Turn the span screw to set
the minimum output pressure. Turn screw counter-clockwise to decrease
and clockwise to increase. It may be necessary to repeat steps until both
end points are at desired values. Replace both covers.

s
When calibrated to operate in the split range mode a full input signal (i.e.
4-20 mA) will operate the unit at one half the normal output span (i.e. 39 psig, 9-15 psig). Setting the unit to operate in the split range mode is
accomplished by positioning internal electrical dip switches. Access
circuit board by first removing the die cast cover of the unit. Then remove
plastic cover by taking out two screws. Position switches as illustrated in
Figure 5. Replace both covers. After replacing covers, refer to the
appropriate calibration procedure (Direct Acting or Reverse Acting) to get
to desired output range (i.e. 3-9 psig, 9-15 psig).

MAINTENANCE
NOTICE
Under normal circumstances, no maintenance should be
required.
Failures due to instrument supply air contamination are not covered by
warranty. Use of oil and/or water saturated instrument air can cause
erratic operation. Poor quality instrument air can result in unit failure. It
is recommended that a filter regulator (such as Dwyer Series AFR) be
placed upstream of each unit where oil and/or water laden instrument air
is suspected. If clean, dry air is not used the orifice can become blocked.
To clean, first turn off supply air, then remove the screw located on the
side of the unit above the “out” port. Unplug the orifice using a wire that
has a smaller diameter than 0.012˝ (0.30 mm). Replace screw tightly into
unit.
WARNING

The Series 2900 Current to Pressure Transducers are not field

not be attempted and may void warranty). Be sure to include a brief
description of the problem plus any relevant application notes. Contact
customer service to receive a return goods authorization number before
shipping.
