The Druck DPI 822 thermocouple loop calibrator provides simultaneous T/C output and mA measurement for transmitter and loop maintenance.
The Druck DPI 822 thermocouple loop calibrator has a 24 V loop power supply to energize transmitters and control loops. An automatic switch test captures open / closed trip values to provide a fast and highly accurate "safety system" check. The Druck DPI 822 thermocouple loop calibrator can be switched into the loop when required by a HART digital communicator and avoids the inconvenience of carrying a 250 ohm resister.
Every Druck DPI 822 thermocouple loop calibrator has an IDOS (Intelligent Digital Output Sensor) compatible port for connecting remote IDOS measurement modules. These include pressure sensors with ranges available from 1psi to 10,000 psi. This feature provides users with a number of unique advantages, for example, a Druck DPI 822 thermocouple 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.
Please consider these optional accessories.
