Specifications

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-, Three- and Four-Wires

Quickly detects faulty sensors and wiring

Pulsed RTD Transmitter Compatibility

Simulation mode

Temperature Test and Measurement

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 Instrumentation and
Loop Maintenance

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

Advanced Features

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