• Comprehensive pH sensor diagnostics warn user of the need for calibration, maintenance, or sensor replacement.

• Easy to use menus with plain language prompts guide the user through calibration and programming procedures.

• INTRINSICALLY SAFE DESIGN allows the transmitter to be used in hazardous environments (with appropriate safety barriers).

• REMOTE COMMUNICATION IS SIMPLE; use the hand-held infrared remote controller or Foundation™ fieldbus host.
Model 50 pH Transmitter

FEATURES AND APPLICATIONS

FOUNDATION FIELDBUS:
The Model 50 is the DO solution for biotech installations requiring Foundation fieldbus communication. This solution offers:

• Speed - 31.25 kbit/s
• Bidirectional Communication of Process Data
• Pure Digital Format for Data Transmission
• Automatic Device Detection and Addressing
• Remote Configuration and Calibration
• Active Measurement, Monitoring and Control

REMOTE COMMUNICATIONS:
The push button infrared remote controller works from as far away as six feet. The Model 50 also communicates via any Foundation fieldbus host.

DIAGNOSTICS:
The internal diagnostics can detect:
• Calibration Error
• High Temperature Error
• Line Failure
• ROM Failure
• Low Temperature Error
• Sensor Failure
• CPU Failure
• Input Warning
Once one of the above is diagnosed, the LCD will display a message describing the failure/default, and an alarm will display at the remote monitoring workstation.

 CALIBRATION:
To reduce errors the Model 50 does not accept calibration data until programmed stability limits have been met. If the data is not acceptable, the transmitter displays an error message and does not update the calibration.

DISPLAY:
The 0.8-inch high LCD main display means values are easy to read even at a distance.

SECURITY:
Access to configuration and reconfiguration modes may be restricted via three levels of user selected security codes.

CASE:
Epoxy painted aluminum.

POWER:
A power supply voltage of 9 VDC to 32 VDC at 22 mA is required.

What is Foundation™ fieldbus

• Purely digital bi-directional communication network connecting field devices and control system

• Field devices transmit multiple variables which enable advanced control and diagnostics

• Plug-and-Play enabled field devices connect to control network and allow ease of configuration

• Field devices utilize a single standard cable for data transfer and to provide power

Foundation fieldbus is a fully digital, bi-directional, communications protocol used for communications between field devices and control systems. The protocol allows for these devices to be drop connected along one field network and loop powered. Additionally they transmit multiple measurement variables to the control system and to other devices for true distributed control. Remote PC workstations can view data trends, perform diagnostics, view alarms, and reconfigure the field device without having to enter the fermentation or cell culture suite.
