Approved Batteries The XP2i-DP is Intrinsically Safe only if powered by one of the following battery types: Approved Battery Type Rayovac Max Plus 815 Energizer E91* Energizer EN91* Duracell MN1500 Replace batteries with approved type in non-hazardous locations only * Energizer is manufactured by Energizer Holdings, Inc., and the Eveready Battery Company, Inc. Many other battery types and models have been tested but failed to meet the requirements for Intrinsic Safety—do not assume other models are equivalent. The XP2i-DP can be operated from an external power supply (P/N 2984). Do not mix battery...

| PRESSURE RANGES, DISPLAY SCALES, AND RESOLUTION psi • Unneeded pressure units may be disabled via the RS-232 connector using ConfigXP software. • An XP2i-DP will indicate pressure up to 10% above its stated pressure rating. Above 110%, the XP2i-DP display will flash, 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. • kPa and MPa models can display...

Applications    DIFFERENTIAL PRESSURE The XP2i-DP may be used to determine accurate differential pressure measurements across a range of applications or installations such as filters, orifice 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. Digital Test Gauge Device Under Test (DUT) The pressure measurement accuracy of the gauge in this example is a combination of the standard...

   CONTINUOUS VACUUM The unique design of the differential 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...

Safety & Certifications    HAZARDOUS LOCATIONS Every XP2i-DP pressure gauge includes the following Intrinsic Safety approvals: Intrinsically Safe and Non-incendive for Hazardous Locations: Class I, Division 1, Groups A, B, C and D, Temperature Code T4 or T3C. !!WARNINGS: The following warnings apply to the XP2i: • • • • • Do not use the RS-232 connector in hazardous locations. Replace batteries in non-hazardous locations and with approved types only. Do not mix battery types or manufacturers. T4 or T3 Temperature Class is based on selection of approved battery. See Approved Batteries on page...

Support    SOFTWARE ConfigXP Configuration Software Use ConfigXP to disable unwanted pressure units, set default pressure units, change water density, adjust calibration, and more via the RS-232 interface. DataLoggerXP Software DataLoggerXP is an optional upgrade to transform the XP2i-DP into a pressure datalogging device.    REPLACEMENT PARTS The only user-replaceable parts are the batteries.    OPTIONS Panel Mounting (Option F4) A panel mount flange allows an XP2i-DP to fit in a 4½" gauge cutout. An XP2i-DP with the F4 option can also be adapted to 6 or 8½" gauge cutouts. Rear Port Fitting...
