Specifications
Instrumentation Test and Loop Maintenance
| DPI 832 Electrical Loop Calibrator |
Measures or sources mA, mV, V and captures switch trip values. It is the ideal instrument for process technicians to check and maintain transmitters, control loops, DCS, PLC input cards and signal conditioners. |
| Programmable Step and Ramp Outputs |
Simplify calibrations and facilitate system diagnostic checks. The ramp output provides a stimulus for rate of change indicators. |
| Adjustable “Nudge” Value |
Provides an incremental output for accurately setting valve positioners and testing switches, relays, trips and alarms |
| Simultaneous Dual Readings |
Simplify transmitter set-up and calibration; for example, source mV, V or mA and measure mA |
| Advanced Features |
Hold, maximum/minimum/average (with time stamp), scaling, tare (offset) and damping filter facilitate system checks and troubleshooting |
| Two Independent 24 V Power Supplies |
Energize 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 for 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 832 electrical loop calibrator can become a fully featured pressure calibrator. |
| Plug and Play |
Modules are interchangeable between instruments, requiring no set-up or instrument calibration.
Please refer to IDOS Universal Pressure Modules data sheet. |
