Rams can determine colour and turbidity, or be used as a limit switch for detecting phase transitions.
It lends itself to a variety of applications in the brewery, wine, dairy, and sugar industries, as well as the chemical and pharmaceutical industry processes.
As a simple limit switch, Rams is used for phase separation during cleaning processes, and to detect product change before the filling station.
Depending on the parameter settings, this detection is based on colour or turbidity.
The output of the relevant parameter takes the form of a current signal; limit formation can be handled externally in the DCS.
As a turbidity meter, it can measure medium to high turbidity values, by means of infrared absorption.
This makes the results virtually independent of product colouration.
For example, in brewery applications, in the hot wort or to control the separator.
For product identification, a fingerprint is first taken and then stored in the Rams.
When a product exhibits these figures in the pipe, it will be identified and signalled.
This is possible for up to eight products via the Rams or unlimited via DCS/PLC.
Installation of the Rams is simple.
It has a compact hygienic design, and is fitted into the product pipe with a standard in-line housing.
It allows CIP and simple calibration correction with tap water.
Other features include a humidity sensor for monitoring condensation; one 4.20mA output free allocatable to one parameter.
A PC-software package is available for configuration and data evaluation and is used by connecting the PC to the Rams with an RS232 interface.
