Mô tả Sản phẩm

The DPI 800 Series is a complete range of advanced, robust and simple to use hand-held instruments. Highly cost effective, these tools are ideal for test/calibration of many popular process parameters. Advanced features and technical innovations address more applications in less time and deliver results you can rely on.

 The DPI 841/842 is the ideal instrument for process technicians and electronic engineers, providing a highly accurate calibration standard and versatile test tool. It measures Hz, kHz, CPM, CPH and pulses. Dedicated features facilitate test and maintenance of electronic circuits and frequency instruments including frequency meters, batch counters, tachometers, motion pickups, integrators and flowmeters.


  • Advanced frequency meter and generator with three output waveforms from 0.1 V to 24 V amplitude
  • Measure or source 0.01 Hz to 50 kHz
  • CPM, CPH and totalizing counter
  • Sine, square and triangular waveforms mA measure, switch test and 24V loop power
  • Large backlit display, menu driven interface
  • HART® loop resistor
  • Robust and weatherproof
  • Compact, simple to use, easy to carry
  • Convenient, one-handed operation
  • Secure grip, impact resistant, elastomer protected
  • Plug/play connector for Intelligent Digital Output Sensors™(IDOS) Universal Measurement Modules

DPI 841 Frequency Loop Calibrator

Automatic Trigger Detects the best value regardless of waveform or amplitude
Frequency Scaling Reads in process units; e.g. flow or revolutions/minute
Programmable Step and Ramp Outputs Simplify calibration and diagnostics
Adjustable “Nudge” Value Provides an incremental output for setting switches, relays, trips and alarms
Advanced Features Hold, maximum/minimum/average (with time stamp), scaling, tare (offset) and damping filter facilitate system checks and troubleshooting

DPI 842 Frequency Loop Calibrator

Dual Readings Provides simultaneous frequency output and mA measurement for transmitter and loop maintenance
24 V Power Supply 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 inH2O to 10,000 psi (25 mbar to 700 bar)
Total Flexibility Means IDOS modules can be used with any compatible instrument; for example, a DPI 842 frequency loop calibrator can become a fully featured pressure calibrator
Plug and Play Modules are interchangeable between instruments, requiring no set-up or instrument calibration.
