Description:

Congratulations on your purchase of the Omega
PX663/665 low differential pressure transmitter.
These transmitters utilize a highly reliable variable
capacitance sensor. A selection of both uni­directional and bi-directional pressure ranges are
offered with accuracy of 0.5% and 1-5Vdc or 4­20mA output signals. The DIN rail-mounting
package offers a new and efficient use of mounting
space for enclosure mount applications. Features
such as the process valve actuator, and front access
test sockets provide value when validating a process
on line or calibrating the unit.

Media:

The PX663/665 series are designed to measure
clean, dry non-corrosive gases. Not for use on
liquids.

Mounting:

The unit can mount to three types of Din rail sizes
including EN50022, EN50035 & EN50045 (not
included). When securing to EN50022 rail first hook
the top portion of the rear clip onto the top of the
rail and push gently into place. To remove simply
place finger behind lower rear lever and pull
forward. To remove from the EN50035 rail, grasp
the unit, push up and rotate the bottom out. For the
EN50045, pull down and rotate the bottom out.
Multiple units can be stacked accross the rail. Tag
holes are fabricated into the lower rear lever and the
housing below the terminal strip for calibration re­ference tagging and/or ID location. Refer to Drawing 1.

Power requirements:

The PX663/665 is wired (3 wire) (2 wire) for
Voltage and Current output respectively. Refer to
Drawing 2.

Voltage Output

The PX663/665 will operate on any unregulated
supply voltage from 12-36Vdc drawing less than
6mA excitation 12–36 Vdc unregulated.

Current Output

The voltage required for a 4-20mA PX663/665 output
is dependent on the loop resistance of the circuit.
Refer to Drawing 3 showing the minimum supply
voltage (Vmin)requiredfor given Loop Resistance(RL).

Front Access Test Jacks:

Provides on-line process reference signal or
calibration signal without disconnecting power
supply wiring. Measurements can be made using a
standard multi-meter or data collection instrument.
Reference signals through the test jacks are made
in series for 4-20mA output and in parallel for
voltage output. Gold plated contacts accept
standard 0.08˝ microtip test leads, snapping in
place for secure measurements.

Process Valve Actuator Features

The rotating process valve actuator in conjunction
with the PX663/665 actuator tool provides two
types of tests including Calibrate (CAL) and Monitor
(MON) through the appropriate Hi and Lo Port of
the process valve actuator tool. In the (CAL) mode
the PX663/665 is isolated from the process and
allows externally generated test pressure input for
calibration. In the (MON) mode system pressures
can be monitored with another instrument without
physically unplugging the process tubes. In this
mode an on-line measurement can be captured.

The valve kit includes an actuator tool and 7˝ of
silicon tubing. The actuator tool identifies the above
positions and tests, including high (HI) and low
(LO) differential pressure reference.

From the (OFF) position the actuator tool can be
inserted and removed. The following tests can be
performed:

Calibration (CAL):

Both zero and Span adjustment pots are non­interactive and accessible from the front of the unit.
Note: Due to the sensing technology used rarely are

actual zero and span adjustments needed. Zero and
span pots are available on the transmitter.

• Insert actuator key.

• A 90-degree clockwise rotation isolates the sensor
from the process.

• Apply zero pressure. This can be best produced by
shorting the HI and LO ports on the actuator key
using the silicon tubing supplied. Verify or make
zero adjustment.

• An external pressure generator can be used to
produce the required span pressure and verify or
make span adjustment, pressure is provided to the
instrument using the 2 ports (HI/LO) on the
actuator tool.

• Measure record signal via front access test jacks.

Monitor (MON):

Provides on line or uninterrupted measurement point
capability when used with the front access test jacks.

• Insert actuator tool

• A 90-degree counterclockwise rotation tee’s the
process to both the sensor and out through the key,
to provide external measurement or recording
capabilities.
