The GE Druck DPI 822 Thermocouple Loop Calibrator provides simultaneous T/C output and mA measurement for transmitter and loop maintenance. The GE Druck DPI822's 24 V Loop Power Supply energizes transmitters and control loops. An Automatic Switch Test captures open/closed trip values providing a fast and highly accurate "safety system" check. Also a HART Resistor can be switched into the GE Druck DPI-822's loop when required by a HART digital communicator and avoids the inconvenience of carrying a 250Ω resistor.

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.
Cold Junction Error 0.4°F (0.2°C) maximum error for 86°F (30°C) change inambient temperature.
