CRATOS - Controller, Transmitter, Analyzer
High Quality - Superior Functionality
Part of a range of controllers, the CRATOS is the big brother of the CRIUS® and offers more sensors, more functionality and more flexibility with a touch screen as standard and optional built in GSM modem, the CRATOS offer a very low cost per measuring point. Optional comms packages allow Profibus, Modbus ASCII, Modbus RTU, Modbus TCP, HART and others.
CRATOS is equipped with the capability to control up to twelve sensors of any type with appropriate analogue outputs and relays. Equipped with PID control capability and datalogging as standard, the CRATOS is very able to control the most complex water treatment processes at a fraction of the cost of other controllers.
CRATOS plus Sensor =
- Free Chlorine Analyzer (HaloSense)
- Total Chlorine Monitor (HaloSense)
- Chlorine Dioxide Analyser (DioSense)
- Ozone Monitor (OzoSense)
- Dissolved Oxygen Meter (OxySense)
- Suspended Solids Monitor (SoliSense®)
- Turbidity Meter (SoliSense®)
- pH Analyser (pHSense)
- ORP Analyser (ORPSense)
- External inputs
- Choose from Standard Configurations or "Build Your Own"
Customers requiring the same functionalities but less than seven sensors or a no-frills controller such as datalogging, on-screen graphical reporting, or remote access via the internet should consider CRIUS® or CRONOS controllers.
Overview
CRATOS is equipped with the capability to control up to 12 sensors of any type with appropriate analogue outputs and relays. Equipped with multiple PID channels and practically infinite datalogging as standard, CRATOS is very able to control complex water treatment processes at a fraction of the cost of other controllers. Customers requiring fewer sensors or a no-frills controller should consider the CRATOS or CRIUS® controllers.
Datalogging
The CRATOS controller (as well as the CRIUS®) has a significant datalogging capacity without the use of an expansion card. On board datalogging consists of two chunks of memory that are filled up one following the other. When the second memory chunk is full it either copies the first memory chunk data to the mini SD card (if present) or starts to overwrite it. This means that the data available on the instrument will vary depending on where you are in the cycle. The minim number of data storage points is c.4000 and the maximum is c.8000 This corresponds to a minimum of 13 days of data for one channel at 5 minute averages. On a two gigabyte micro SD card this corresponds over 1000 years for a single channel at 5 minute averages. In order to get the instrument to copy all data from the onboard datalog to the micro SD card the user simply goes to the appropriate part of the memory and presses the button 'save all'.
