Overview
INTRODUCTION
Thank you for choosing the XP2i-DP Digital Test Gauge from Crystal Engineering Corporation. The XP2i-DP is a combination of leading edge
technology, double-sided isolated dierential pressure sensing, and rugged industrial design.
Overview 1
Based on the XP2i S
0.1% of reading accuracy wet/wet dierential transducer
•
Excellent performance in long term high vacuum applications

OPERATING INSTRUCTIONS
The XP2i-DP operates just like all the XP2i Series products. The uniqueness of the dierential pressure capability comes from the integration of the dieren-
tial sensor and process tting system. The keypad and remote functions are the same as on all XP2i Series products. For further details about these common
eatures, refer to the XP2i Operation Manual (P/N 4870).
f
eries platform, the –DP has all the key features of the product line with additional capabilities that include:

An XP2i-DP will indicate pressure up to 10% above its stated pressure rating. Above 110%, the XP2i-DP display will ash, indicating that the applied pressure

exceeds the calibrated pressure range. If the calibrated pressure range is exceeded, the pressure displayed may not be accurate.
Overpressure is the maximum pressure the gauge can withstand without damage. The gauge will not indicate pressure up to this value.

Applications
DIFFERENTIAL PRESSURE
The XP2i-DP may be used to determine accurate dierential pressure measurements across a range of applications or installations such as lters,
orice plates, valves, etc. For example, in a piping system with an upstream static pressure of approximately 80 psig, the XP2i-DP may be used to
determine the 10 psid pressure drop across the device under test (DUT). In this case, the product would be connected as shown below.

PSI
The pressure measurement accuracy of the gauge in this example is a combination of the standard accuracy statement and the static line pres-
sure eect. The 10 psid pressure, when compared to the 100 psi full scale product used, will require the 0 to 20% of Full Scale, ± (0.02% of Full
Scale) accuracy statement. The static line pressure eect relates to the lowest test pressure applied in the test, or in this case 70 psi.
The pressure measurement accuracy for this test condition is as follows:
(0.02% x 100 psi) + (0.0003 psi x 70 psi) = ± 0.04 psi.
±
When using a 15 psi full scale gauge, this will require the 20 to 100% of Full Scale, ± (0.1% of Reading) accuracy statement.
± (0.1% x 10 psi) + (0.0003 psi x 70 psi) = ± 0.031 psi.
XP2i-DP Operation Manual
CONTINUOUS VACUUM
Vent Vacuum
The unique design of the dierential pressure sensor integrated into the XP2i-DP allows for long term vacuum use without fear of permanent damage to the
sensing chip or package. When measuring high vacuum gauge pressures continuously it is recommended to connect the static line pressure to the right ()
port marked "Vacuum this side". To achieve gauge measurements, the left (+) port is left vented to atmospheric pressure.
Note: When connected in this orientation, the XP2i-DP display will invert the sign on the gauge display. For example, a pressure of -12 psi on the negative
port will display +12 psi. To invert the sign to read -12 psi, use CongXP Software (V 2.4 or later).
Applications 7
Select Enable Vacuum Mode and update the gauge to properly display a negative pressure value.
WARNING: Pressure applied to the + sensor port must be greater than or equal to the pressure applied to the – sensor port.
!
The vacuum accuracy of the gauge will be calculated the same as a dierential measurement. Therefore, the 12 psi measurement, when compared to a 100
psi full scale gauge used, will require the 0 to 20% of Full Scale, ± 0.02 % of Full Scale accuracy statement.
The vacuum accuracy for this test condition is as follows:
(0.02% x 100 psi) = ± 0.02 psi.
±
When using a 15 psi full scale gauge, this will require the 20 to 100% of Full Scale, ± (0.1% of Reading) accuracy statement.
± (0.1% x 12 psi) = ± 0.012 psi.

•
Do not mix battery types or manufacturers.
•
T4 or T3 Temperature Class is based on selection of approved battery. See Approved Batteries on page 4.

Special conditions for safe use:
•
T4/T3 Ga
Intrinsically Safe and Non-incendive for Hazardous Locations: Class I, Division 1,
Groups A, B, C and D, Temperature Code T4 or T3C.
• The equipment shall not be installed in a location where external conditions are conducive to the buildup of electrostatic charge.
• Because the enclosure of the XP2i and XP2i-DD is made of aluminium, if it is mounted in an area where the use of category 1 G apparatus
is required, it must be installed such that, even in the event of rare incidents, ignition sources due to impact and friction sparks are excluded.
