SPECIFICATIONS
Model 60—DO Transmitter Specifications
Input: NanoAmp input from polarographic DO sensor accepts industry standard 22K temperature compensator.
Output: One isolated 0/4–20 mA outputs with superimposed HART digital signal.
Calibration and Measurement: Will accept manual input of process pressure in mm Hg, inches Hg or bar. Measures partial pressure of oxygen and displays it as % saturation or ppm. Can set the zero point electronically or with inert gas.
Relays: Three programmable relays, activated according to setpoints. Each handles up to 5 amps.
Security: Option to set a passcode allowing “read only” or full access to all functions: Calibrate, Program and Display.
Configuration: Clear alphanumeric display with text prompts. User selectable automatic and manual temperature compensation. Easy to configure and program.
Physical Characteristics: Two-line, 16-character, back-lit LCD display. NEMA 4X (IP65) housing, weatherproof and corrosion resistant. CE approved.
Mounting Hardware: Available in either pipe or panel mount versions. Cable grips not included.
Power Supply Requirements: 24 Vdc.
Top Considerations:
• Clear, easy-to-read, back-lit display
• Full text prompts
• Easy programming
• Passcode protected menus

What is HART?
• Digital signal superimposed over a conventional analog 4-20 mA signal
• Two channels of communication to the control room, one analog and one digital
• 4-20 mA signal carries the primary variable, digital signal carries secondary variables
• Bi-directional communication between the device and the control system
Features and Benefits
HART Provides two data channels
One analog 4-20 mA channel and one superimposed bi-directional digital channel link the field device to the control system. The analog 4-20 mA signal carries the primary variable while the digital signal carries secondary variables, device configuration data, and diagnostic alerts.
Advanced Sensor Diagnostics
Digital channel provides secondary variables for implementation of advanced sensor diagnostics which allows for improved performance and greater reliability.
Remote Viewing of Data
Remote viewing of measurement data and remote reconfiguration of field device made possible over the bi-directional digital channel by any PC based workstation with an interface software package such as Asset Management Solutions (AMS).
Compatible with 21 CFR Part 11 Compliant Software
The HART digital signal enables the recording of measurement variables into a 21 CFR Part 11 compliant software package, reducing labor hours in the collection and documentation of measurements by operators. |
