FUNCTION
Pressure sensor CPS-D-A-9500 has an inte-
grated differential pressure element that is tem-
perature compensated for high accuracy and
linearity. The pressure element and the output
signal has high resolution which means that the
pressure value is presented in increments of
max 2 Pa over the entire measurement range
(-100 till +9500 Pa).
Via a backlit display, the desired function is set;
differential pressure sensor, volume / flow sen-
sor or pressure regulator. The output signal
(0-10V or 4-20 mA), K factor for volume flow
calculation, measrurement range / set point and
required signal damping are also set via the dis-
play. Zero calibration of the pressure element
is also carried out via the display. Basic display
mode shows the current measured value (pres-
sure or volume / flow), current output in volts or
milliamps and set point at regulator function.
MOUNTING
CPS-D-A-9500 is wall-mounted with the hose
connectors pointing downwards. See figure
2. Install the CPS-D-A-9500 on a level sur-
face. The terminal block and enclosure cable
port (with a pre-mounted M16 cable gland) are
removable for easier installation. See figure 1.
The enclosure cover is hinged at the top, has a
snap fastener at the bottom and catches to keep
the cover in raised position.
INSTALLATION
Open the cover on the CPS-D-A-9500 to access
the programming buttons on the display card.
Press ENT (Enter) to access the settings menu
and use the up and down arrows to navigate the
submenus. Select your submenu and confirm by
pressing ENT.
MAINTENANCE
CPS-D-A-9500 is normally maintenance free.
Use zero pressure calibration when necessary.

CPS-D-A-9500 comes factory set for differential
pressure measurement of ranges 0-5000 Pa, 0-10V
output signal and signal damping 10 sec. To change
ranges, go to the Range submenu and set the
desired start and max. values. You can adjust these
values using the arrow keys in increments of 50 Pa,
from -100 Pa to 9500 Pa.
Via the K factor settings, CPS-D-A-9500 can mea-
sure the volume / flow over, e.g., fans or orifice
plates. Select Volume from the Function menu. Here
you can set the k factor and volume unit.
The selectable conversion formulas from differential
pressure to volume are: q=Kx√∆p (default), 1/Kx√Δp,
√Δp/K and Kx√(2/ρ)x√Δp. [ρ=1.2].
K factor can be rounded up to two decimal places.
The following units can also be set: m³/h, m³/s or
l/s. The unit setting is only a "display label" and not
a mathematical calculation of the value. To select
ranges, go to the Range submenu and set the
desired start and max. values. These values are
adjusted optionally with arrow buttons 0-32000, in
increments of 100 up to 9500 and in increments of
500 above.
Example: K factor: 100.00 and Differential Pressure:
500 Pa. The root of 500 = 22.36 multiplied by 100.00
= 2236. The volume flow is 2236.
The volume unit of
the calculation (m³/h, m³/second or liters/second) is
specified by the manufacturer of the fan/orifice plate.
The measurement range determines at which mea-
sured value the output signal will start and when the
maximum output signal will be given. If the current
measurement is above the set range, the display
flashes and shows > Range under the measurement
value. For differential pressure measurement, a
range starting with negative numbers can be set (-50
or -100 Pa). If the current measurement is under the
set range, the display flashes and shows < Range
under the measurement value.
Output signal damping (averaging) is adjustable at
3 levels: 3, 10 and 20 seconds. To adjust, select the
Damping submenu from the Settings menu.
For pressure regulation, select “Regulator” in the
“Function" menu. The set point is adjustable from
0-9000 Pa. To avoid overthrow, adjust the regulation
speed (1-10) in the “Reg.speed” submenu, where 10
is the fastest regulation speed. The regulator output
is 0-10V DC. Adjust the minimum and maximum out-
put (0-100%) in the “Out range” submenu.
Hose connections:
There are two hose connections marked plus (+) and
minus (-) on the outside of the enclosure. Connect
the positive pressure hose to plus (+) and the nega-
tive pressure hose to minus (-). See figure 2.
Electrical installation:
Connect the CPS-D-A-9500 with a three-wire con-
nection with common signal and supply ground. See
figure. 3.
Test function:
When the display is in basic display mode, the sensor
emits max. and min. output (0/10V or 4/20 mA) when
you press the up button (↑) or down button (↓). The
current output signal (0-10V or 4-20 mA) is shown
next to the text "Out:" in the display.
ZERO PRESSURE CALIBRATION
When commissioning, a zero pressure calibration is
recommended. Allow the pressure sensor to reach
its operating temperature before the zero calibration.
Remove all external hoses and select the 0-Calibr
submenu from the Settings menu. When the calibra-
tion is completed it will show on the display.
