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.
Features:
Measure and source thermocouples
Advanced Cold Junction compensation virtually eliminates errors due to ambient temperature changes
