The Druck DPI 812 is an RTD loop calibrator.
The Druck DPI 812 RTD calibrator contains multiple advanced features to increase its versatility and reliability:
The fully programmable automatic outputs available on the Druck DPI 812 RTD calibrator allow single-handed testing of control loops. By leaving a Druck DPI 812 RTD calibrator at the end of the control loop to generate a pre-programmed step or ramp sequence, the technician is free to go to the control room to observe the DCS and system indicators. Two technicians communicating by radio are required for this test when using conventional equipment.
Every Druck DPI 812 RTD calibrator has an IDOS (Intelligent Digital Output Sensor) compatible port for connecting remote IDOS measurement modules. These include pressure sensors with ranges available from 1 psi to 10,000 psi. This feature provides users with a number of unique advantages, for example, a Druck DPI 812 RTD 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.
A 247 ohm resistor, selected from the menu, is switched into the circuit when testing and setting HART ® transmitters in conjunction with a communicator. It allows reading of the HART ® digital signals by the communicator. Some competitors provide such a feature but more often than not, opening of the instrument case is necessary to change a link on the PCB. This is very inconvenient and results in a broken calibration seal, which is usually unacceptable.
The Druck DPI 812 RTD loop calibrator includes an optional loop calibrator which further increases its versatility. New functions include:
Please consider these optional accessories.
