Crystal Engineering’s XP2i-DP Differential Pressure Test Gauge features the most innovative technology and double-sided isolated differential pressure sensing, all encompassed in a durable design. In addition to all the features of the Crystal XP2i Pressure Gauge, the intrinsically safe XP2i-DP offers expanded capabilities, including 0.1% of reading accuracy wet/wet differential transducer and an incomparable level of performance in long term high vacuum applications. The XP2i-DP is also customizable, meeting a greater range of application requirements, for either portable or panel mounting configurations.
For even more benefits, the DataLoggerXP upgrade offers an Ultra Low Power (ULP) Mode, the capacity to data log pressure to 32,000 data points and more than an entire year of unremitting recording time.
DIFFERENTIAL PRESSURE ACCURACY | |
20 to 100% of Full Scale | ±(0.1% of Reading + Static Line Effect) |
0 to 20% of Full Scale | ±(0.02% of Full Scale + Static Line Effect) |
Static Line Effect: 0.0003 psi/psi of lowest static pressure. Includes all effects of linearity, hysteresis, repeatability, temperature, and stability for one year | |
