EXTSEN operational bulletin 4
Introduction
The EXTSEN units connect a pressure controller (with no internal pressure
sensor) to an end-user supplied external pressure transducer. The EXTSEN
combines the sensing ability of an existing pressure transducer with an
Alicat electronics package and an internal PID algorithm.
Example setup
The EXTSEN receives a linear analog signal from the external transducer.
This analog signal corresponds to a full scale range that is specified by the
user at the time of order, and corresponds to the scale of the external
transducer. The EXTSEN device interprets this analog signal as its sensed
pressure.
Please refer to the PC-Series or PCD-Series operating manual for complete
information regarding use and tuning of your pressure controller.

Pinouts
Primary Connector Pinout
If ordered only with a standard Alicat 8-pin mini-DIN, M12, 9-pin D-SUB, or
15-pin D-SUB connector, the sensor input pin will replace the secondary
analog output pin, unless otherwise specified in the part number or the
device is ordered with a secondary sensor input connector.

Secondary Connector Pinout
EXTSEN pressure controllers may be ordered with a secondary connector
specifically for communication and powering the external transducer. Any
EXTSEN device that is configured with the industrial protocol board for
EtherNet/IP, EtherCAT, MODBUS TCP/IP, etc., will need to use a secondary
connector for the sensor input.
Caution: When using a secondary connector as a dedicated
connection to the transducer
, do not wire any signal input into the
primary connector of your device.

Setup Menu
The EXTSEN SETUP Menu provides additional configuration and calibration
of the EXTSEN pressure controller. The EXTSEN device can adapt to
multiple transducers and ranges in the field.
The EXTSEN will be configured for a specific full scale pressure range,
input signal, and signal type out of the box. Here are some reasons why
you would want to use the EXTSEN SETUP Menu:
1. Pairing an external transducer with a
different full scale pressure range than
the preconfigured range for the EXTSEN
device.
2. Changing the pressure controller's
settings to match an external
transducer's signal calibration. The
transducer could have previously been
configured for a 4–20 mA current signal,
or a 0.5–4.5 V signal, while the
controller was calibrated for a 0–5 V
transducer.
3. Modifying the slope for a paired transducer after the pressure/volt
has been characterized.
MENU ADV SETUP SENSOR SETUP EXTSEN SETUP
This is the base menu for configuration and calibration. This is how you
adjust the range and calibrate the input for your EXTSEN device.
The values in the middle of the screen are your pressure readings and your
input signal read by the Alicat in volts (V) or current (mA).
•LIVE CAL calibrate an attached pressure transducer
•TYPE/RANGE set the type and range of the attached transducer
•CAL VALUES enter in previously collected calibration data
•BACK go back to the Advanced Setup Menu
•INTRNL VALUES contain the internal offset and gain calculated from
either LIVE CAL or CAL VALUES
•MAIN go back to Main Display

EXTSEN operational bulletin 9
LIVE CAL
This menu allows you to perform a live
calibration when a pressure transducer or
process calibrator is connected the EXTSEN
device. Press SET AS ZERO to set the zero
point, the pressure reading should go to zero
regardless of the transducer input. Then use
CAL GAIN to ensure the device reads the
desired pressure value at another signal
level. The device will calculate a new gain
value for the transducer input.
•SET AS ZERO set the current signal level
as zero pressure
•CAL GAIN ensure the device pressure reading matches the
reference transducer value
•BACK go back to EXTSEN Setup Menu
•MAIN go back Main Display
There will be a warning when CAL GAIN is pressed to ensure everything is
configured properly before setting your reference pressure.
✓
Note: Ensure the transducer type (absolute, gauge, or differential),
transducer range, and signal type and range are configured before
performing a live calibration.

EXTSEN operational bulletin 10
TYPE/RANGE
This menu configures the type and range of
the connected pressure transducer.
•TYPE configure the EXTSEN with the
type of pressure (absolute, gauge, or
differential)
•RANGE configure the full scale range of
the pressure transducer
•BACK return to the EXTSEN Setup Menu
•MAIN go back Main Display

Note: Pressure engineering units are set in BASIC CONFIG under
DEVICE UNITS.

This menu allows you to input known
information about an external pressure
transducer. The EXTSEN device will calculate
new gain and offset values for the input
values in these menus.
•OFFSETset the reading of the pressure
transducer when at minimum signal
•SLOPE set the slope of the transducer in
terms of pressure / (V or mA) of the
pressure transducer
•BACK return to the EXTSEN Setup Menu
•SIGNAL enter in the nominal signal range of the pressure

SIGNAL MENU
This is where the nominal signal range is
entered. Common values for signal range are
0–5V, 0–10V, 0.5–4.5V, and 4–20 mA.
If the EXTSEN device is calibrated in volts
and current is chosen in the SENSE Menu, a
sub-menu is shown to specify the sense
resistor being used. The sense resistor would
be integrated into the pressure transducer or
the cabling used; it is not internal to the Alicat
device.
•MIN SIGNAL minimum signal value
•MAX SIGNAL maximum signal value
