System signals

Analogue signals:

Each In-Site ' Channel' can accommodate up to 10 separate analogue signals, all being monitored simultaneously. The Graph and Verification Reports detail the values of each signal during each processing or cleaning operations.

Typical instrument probes/sensors monitored being:

CIP delivery and return:

CIP return (dairies):

CIP tank farm:

CIP systems:

Process plant:

Effluent flume/plant

Temperature, Conductivity, Flow, pH

Turbidity or Suspended Solids

Temperature, Conductivity, Volume

Proportional valves and pumps

Temperature, volume/weight

pH, Conductivity, T.S.S. Volume, Flow

Digital signals:

Each Channel monitors numerous digital signals, typically

Per channel

Selection type

Clean type

Group type

Selections

Storage tanks, Pipe lines, Pasteurisers, etc.

1-100 or 1-500

Stages

CIP/Process stages or cycles

1-10

e.g. pre-rinse, detergent, line purge, etc.

Status Signals

plant items

1-32 or 1-64

e.g. pumps, valves, level probes, etc.

Meters

pulse units

1-5

measuring water, chemicals, etc.

Most sites have CIP process controllers that confirm specific tasks were carried out correctly or set parameters were achieved.

The In-Site system also does this but is specifically configured to provide telegraphic information on what was not done correctly.
