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
