The Right Sensors

The Hach si792 E Inductive (Electrodeless) Conductivity 2-wire Transmitter is designed for use with Hach GLI world-class 3700-series inductive conductivity sensors. The innovative technology of electrodeless sensors reduces polarization and electrode coating problems in harsh environments. Sensors are available in sanitary (CIP) flange and convertible styles in PFA®, PEEK®, PVDF, and polypropylene.

Multiple Communication Protocols

The si792 E transmitter is available with digital communication functionality to connect easily to a communication network of choice, including HART®, PROFIBUS PA, or Foundation® Fieldbus.

Area Rate to Suit Your Needs

The si792 E transmitter is available as Class I, Division 2 (C I, D 2) with HART communications only or as intrinsically safe, Class I, Division 1 (C I, D 1) with HART, PROFIBUS PA, or Foundation Fieldbus. FM, CSA, and ATEX certified.

Easy-to-use Intuitive Interface

A logical menu structure, combined with icon based messages allows for intuitive operation. The large, clear liquid crystal display shows the measurement value, process temperature, and sensor and transmitter status. A transmitter or sensor error is indicated by a bright red LED and a message is displayed.

Sensor Diagnostics

The si792 E transmitter performs self-diagnostics and sensor monitoring such as asymmetry potential, slope, response time, cable integrity, glass, and reference impedance.
