Temperature Test and Measurement

DPI 821 Thermocouple Calibrator Measures or simulates thermocouple sensors and is the ideal tool for checking probes, indicators and controllers
Unique Cold Junction Compensation Virtually eliminates ambient temperature errors. (Patent pending)

DPI 821/822 - Thermocouple Graph

Advanced Features Step, ramp, scaling, maximum/minimum/average, and hold facilitate system checks and troubleshooting

Temperature Instrumentation and Loop Maintenance

DPI 822 Thermocouple Loop Calibrator Provides simultaneous T/C output and mA measurement for transmitter and loop maintenance
24 V Loop Power Supply Energizes transmitters and control loops
Automatic Switch Test Captures open/closed trip values providing a fast and highly accurate “safety system” check
HART Resistor Can be switched into the loop when required by a HART digital communicator and avoids the inconvenience of carrying a 250 O resistor

IDOS Flexibility

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 822 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.
Please refer to IDOS UPM data sheet.
