FEATURES AND APPLICATIONS:

HART: The Model 40 is the pH solution for biotech installations requiring HART communication. This solution offers:
• Speed - 1.2 kbit/s
• Bidirectional Communication of Process Data
• Digital Information Riding on 4-20 mA Signal
• Remote Configuration & Calibration

Clear Back-lit DISPLAY:
Clear, easy-to-read, back-lit dot-matrix LCD display, with fully descriptive diagnostic messages and easy-to-use interface, spells out each operation in English, French, German, Italian, or Spanish. The display continuously indicates the measured variable in large numerals, along with the temperature, output value and two user selectable process parameters.

Automatic CALIBRATION:
The automatic buffer recognition feature uses stored buffer values and their temperature curves for the most common buffer standards available worldwide.

Advanced DIAGNOSTICS:
The state-of-the-art, continuous diagnostic capability of the Model 40 transmitter eliminates troubleshooting guesswork by alerting the user to the following problems:

• Cracked or broken pH electrode
• Aged glass
• Non-immersed electrode
• Poisoned reference (offline only)
• Faulty temperature element
• pH electrode slope error (offline)
• Analyzer electronics failure

In the event of one of these conditions, the transmitter will display a descriptive message of the problem, illuminate a red LED on the front panel, and alarm at the remote monitoring workstation.

Compatible with 21 CFR 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.

A natural evolution of the 4-20 mA protocol, HART is a digital protocol that is superimposed over a conventional 4-20 mA signal, which still carries the primary variable. This digital signal allows the simultaneous transmission of additional measurements to the control system that will enable advanced sensor monitoring and diagnostics. The digital signal is bi-directional which allows the remote monitoring and configuration of the field device by the use of Asset Management Solutions (AMS) software on any networked PC and thus enables remote troubleshooting and reduces false alarms which waste valuable time.
