Specifications

Pressure Test and Measurement
| DPI 800 Pressure Indicator | The ideal tool for pressure test and measurement |
|---|---|
| Pressure Ranges | 10 in H2O to 10,000 psi (25 mbar to 700 bar) including vacuum options |
| All-Inclusive Accuracy | Can be relied on from one year to the next, even in tough environmental conditions (see specifications) |
| Dual Sensor Configuration | Extended measurement range and simultaneous two channel reading (P1 and P2 or P1 – P2) |
| Stainless Steel Sensor Construction | Available for compatibility with a wide range of fluids and gases (refer to range table) |
| Programmable Leak Test | Reports the pressure drop and leak rate |
| Advanced Features | Hold, maximum/minimum/average, alarm, and tare facilitate troubleshooting |
Pressure Instrument and Loop Maintenance
| DPI 802 Pressure Loop Calibrator | Provides simultaneous pressure and mA measurement for transmitter and loop maintenance |
|---|---|
| Dual Readings | Simultaneous measurement of pressure and mA for transmitter calibration and loop maintenance |
| 24V Loop Power Supply | Energizes transmitters and control loops |
| Automatic Switch Test | Captures open/closed trip values providing a fast and highly accurate “safety system” check |
| HART Resistor | Can be switched into the loop when required by a HART digital communicator and avoids the inconvenience of carrying a 250 O resistor |

IDOS™ Flexibility
| Intelligent Digital Output Sensor (IDOS) | Universal Pressure Modules are available from 10 in H2O to 10,000 psi (25 mbar to 700 bar). |
|---|---|
| Total Flexibility | IDOS modules can be used with any compatible instrument; for example, a DPI 812 RTD loop calibrator can become a fully featured pressure calibrator. |
| Plug and Play | Modules are interchangeable between instruments, requiring no set-up or instrument calibration. |
| Range Expansion | Achieved by adding modules (please refer to the IDOS Universal Pressure Module datasheet). |

| *S_Standard Accuracy | Total accuracy over 32°F to 122°F (0°C to 50°C), including one year stability and calibration uncertainty |
|---|---|
| *P_Premier Accuracy | Precision over 65°F to 82°F (18°C to 28°C) For operation over 41°F to 113°F (5°C to 45°C): 0.014% FS for ranges above 10 psi (700 mbar) 0.075% FS for ranges below 15 psi (1 bar) Stability over a year: 0.01% reading ranges above 5 psi (350 mbar) 0.03% reading ranges below 10 psi (700 mbar) Calibration uncertainty: 50 ppm of reading |
| Single or Dual Range | One or two internal sensors can be selected. For dual range instruments, G/D ranges will be configured as G (gauge). Only one of the two sensors can be 1500 psi (100 bar) or above. |
| Overpressure (maximum transient/intermittent pressure) | 5 psi (350 mbar) and below 4 x FS 10 to 10,000 psi (700 mbar to 700 bar) 2 x FS Maximum working pressure: 1.1 x FS |
| Pressure Connections | 1/8 NPT female or G 1/8 female |
