Loop Maintenance

DPI 812 RTD Loop Calibrator

Provides simultaneous RTD output and mA measurement for transmitter/loop maintenance

24V 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 S resistor

Temperature Test and Measurement

IDOS™ Flexibility

DPI 811 RTD Calibrator

Measures or simulates RTD sensor and is the ideal tool for checking probes, indicators, recorders and controllers

Automatic Detection of Two-, Threeand Four-Wires

Quickly detects faulty sensors and wiring

Pulsed RTD Transmitter Compatibility

Simulation mode

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 812 RTD loop calibrator can become a fully featured pressure calibrator.
