GE's Druck DPI 880 is an ultra-compact and simple-to-use multifunction calibrator for testing, configuring and calibrating virtually all process parameters. It is 35% smaller than competitive models and it’s interactive display means a more simple, easier-to-understand interface.

Users no longer need to carry additional recording tools using the data logging capability, can obtain high precision data and address any issue in as much time as it takes to press a button, saving valuable operating time.
 

Applications

• Test and maintenance
• Transmitter calibration
• Loop set-up and diagnostics
• Switch, trip and alarm verification

The DPI 880 Multi-function Calibrator is an ultra compact and simple to use tool for testing, configuring and calibrating virtually all process parameters. It measures, sources and simulates mA, mV, V, RTDs, thermocouples, ohms, frequency, pulses and pressure, captures switch values and provides 24 V loop power.
 

Simultaneous dual readings

Reads both input and output parameters simplifying calibrations and system diagnostics. Calibration values are captured on one screen and adjustments are seen in real time, for example, when making zero and span adjustments.

• Programmable step and ramp outputs
  Quickly step through calibrations with the %Step output or make zero and full scale adjustments using Span Check. The Ramp output is ideal for delicate analogue meters, rate of change indicators and checking valve travel and slew rates.
• Adjustable nudge output
  Provides small incremental output changes for accurately setting valve positioners, switches, trips, and alarms.
• 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 avoiding the inconvenience of carrying a 250 Ω resistor.
• 24V loop power supply
  Energises transmitters and control loops.

Temperature

Measures or simulates RTD or thermocouple sensors and is the ideal tool for checking probes, transmitters, process loops, indicators and controllers. Use with a temperature probe to provide a versatile thermometer.

Unique thermocouple cold junction compensation
Virtually eliminates errors caused by changing environmental conditions on test instruments used outside.
 

Automatic detection of 2, 3 and 4 wire RTDs
Quickly detect damaged sensors and faulty wiring that could otherwise be missed or cause system inaccuracy.

Thermometer with wide probe compatibility
Compatibility with 8 RTDs and 12 thermocouples allows probe selection for any thermometer application, e.g. general purpose, high temperature, hygienic and aggressive media.

Frequency

Measures or sources Hz, kHz, CPM and CPH providing a highly accurate calibration standard and versatile test tool for process technicians and electronic engineers. Dedicated features facilitate test and maintenance of electronic circuits, frequency/flow meters, batch counters, tachometers, and motion pickups.

Automatic trigger
Detects the best value regardless of waveform or amplitude.

Pressure

Intelligent Digital Output Sensor (IDOS) Pressure Modules are available from 10 in H2O to 10,000 psi (25 mbar to 700 bar). IDOS modules are Plug & Play requiring no instrument calibration or set-up to provide a fully featured pressure calibrator.

Standard and Premier accuracy
Standard accuracy from 0.05% FS includes operation over 32°F to 122°F (0°C to 50°C), one year stability and calibration uncertainty. The Premier range provides laboratory grade precision to 0.01% FS.

Total flexibility
IDOS modules can be used with any compatible instrument carrying the IDOS logo; for example, the DPI 800 series and DPI 150.
