The Druck DPI 832 electrical loop calibrator is a lightweight and convenient hand-held
instrument for testing control loops and for setting up distributed control systems (DCS),
programmable logic controllers (PLCs), and signal conditioners in process and industrial
control systems.
The multifunctional GEDruck DPI 832 electrical loop calibrator provides the ability to source
and measure millivolts, milliamps, or volts while simultaneously measuring milliamps or capturing
switch trip values. With dual reading capability and a large display, the Druck DPI 832
electrical loop calibrator is the ideal solution for process technicians to check and maintain
transmitters, control loops, DCS, PLC input cards, and signal conditioners.
Every Druck DPI 832 electrical loop calibrator has an IDOS (Intelligent Digital Output Sensor)
compatible port for connecting remote IDOS measurement modules. For example, a Druck DPI 832
electrical loop calibrator can become a fully functional pressure calibrator by adding a universal
pressure module. IDOS measurement modules are interchangeable between any IDOS compatible
instruments without calibration or set-up. They are true "plug and play" modules.
Applications for the Druck DPI 832 Electrical Loop Calibrators
- Process instrument test and maintenance
- Control loop setup and diagnostics
- Set-up DCS, PLC, and signal conditioners
- Valve positioner adjustment
In addition, Druck DPI 832 electrical loop calibrators have multiple advanced features to increase
their versatility and reliability:
-
Advanced Features: Hold, maximum/minimum/average (with time stamp), scaling, tare
(offset), and damping filter facilitate system checks and troubleshooting.
-
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.
- 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 250Ω resistor.
