Highly cost effective, the GE Druck DPI 812 is 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 GE Druck DPI 812 RTD Loop Calibrator provides simultaneous RTD output and mA measurement for transmitter/loop maintenance.

The fully programmable automatic outputs available on the GE Druck DPI 812 RTD calibrator allow single-handed testing of control loops. By leaving a GE 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 GE 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 GE 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.
