SS2043 02/26/99 Rev.A

General Information
The PX2300 Series pressure transmitters have been carefully tested and calibrated

before shipment. Specific performance information is listed on the specification bulletin
for the transmitter. The PX2300 is designed to be used as a wet-to-wet differential
pressure transmitter with a 4 to 20 mA output and is contained in a NEMA 4 housing
enclosure.

Environmental Conditions
The PX2300 is designed to be operated and be stored under the following environmen-

tal conditions:

Temperature

Operating: 0 to 1750F (-18 to 800C)
Storage: -65 to 2500F (-54 to 1260C)

Media Compatibility

The media exposure to the wetted parts of the PX2300 Series pressure transmitter must
be compatible with 17-4 stainless steel, 300 series stainless steel, and Viton (Silicone).

Induced Environments

The PX2300 Series can withstand the following environments for vibration, shock and
acceleration. Keep in mind that the unit accuracy is affected during each of these
conditions and, although no permanent changes to performance will occur, means
should be taken to avoid these induced environments to the best extent possible to
provide the most accurate measurement:

Vibration: 2g from 5 to 500 Hz
Shock: 50g operating, 1/2 sine 10 ms
Acceleration: 10g maximum

Electrical Connections

Current Output Transmitters

The current output transmitters are true 2-wire (see Figure 1A), 4-20mA current devices
and deliver rated current into any external load of 0-800 ohms. The 4-20mA current
output units are designed to have current flow in one direction only – please observe
polarity.

We suggest that any electrical cable shield be connected
to the system’s loop circuit ground to improve electrical
noise rejection.
To access electrical connections remove cover on top of
the PX2300 Series transmitter (See Figure 1).

The PX2300 can operate over a voltage range of 9 to
30 VDC. It has been factory calibrated at 24VDC into a
250 ohm load. The minimum and maximum power
supply must be capable of delivering these voltages to
the PX2300. Thus, the minimum and maximum power
supply calculation is shown below and is depicted in
Figure 2.

MIN Supply Voltage: 9 + 0.02 x (resistance of receiver plus line)
MAX Supply Voltage: 30 + .004 x (resistance of receiver plus line)

The PX2300 Series comes with a 7/8” diameter port intended for a 1/2” I.D. conduit
connection. Contact factory for suggested fittings.
