PRO Series Transmitter,Electrodeless Conductivity
The economical PRO-E3 Transmitter is easy to use with its menu-guided user interface. The NEMA 4X enclosure can be panel, wall, pipe, or integral sensor mounted. The interface is identical to GLI33-series analyzers. Versatile 2, 3, or 4-wire hookup capability. Isolated 4 - 20 mA output.
Introduction
The economical PRO-E3 Transmitter is easy to use with its menu-guided user interface. The NEMA 4X enclosure can be panel, wall, pipe, or integral sensor mounted. The interface is identical to GLI's 33-series analyzers. Versatile 2, 3, or 4-wire hookup capability. Isolated 4 - 20 mA output. The transmitter is also passcode protected.
Benefits
Menu-guided Operation
The simple keypad and logical menu structure make this analyzer easy to use. Menu screens guide you through setup, calibration, operation, and test/maintenance functions.
Multiple Language Capability
All screens can be selected for display in English, French, German, or Spanish.
Versatile Hookup Capability
PRO-series transmitters can be wired in a two, three, or four-wire hookup arrangement to meet your application requirement.
Isolated 0/4 - 20 mA Analog Output
The isolated analog output can be set to 0 - 20 mA or 4 - 20 mA, and assigned to represent the measured parameter or temperature. During calibration, the output is automatically held at the last measured value and, upon completion, returned to its active state.
Passcode-protected Access
For security, use the passcode capability to restrict access to configuration settings and calibration to authorized personnel only.
