1 TURBIDITY MEASUREMENT SYSTEMS
1.1 Introduction
An ABB Turbidity System comprises a 4670 wall-mounted, or
4675 panel-mounted, analyzer, together with one of five sensor
models 7997 200 to 7997 405.
The
analyzer
provides
communications to other devices.
The signal from the sensing system is converted by the analyzer,
and the information is presented on a large, custom-designed,
easy-to-read, backlit liquid crystal display (LCD).

Table 1.1 Coding System
The analyzers can be programmed to work with any of the 7997
sensors, and the operating range can also be configured to
meet users' requirements.
Available in a wall-mount or
analyzer is protected to IP66, ensuring reliable operation in the
and
most demanding situations. The same level of protection is
maintained during programming and calibration.
Details of the individual sensors are given in Table 1.1 below:
