25.1. TDS + SWSG 4 – 20mA
25.1.1. Specification
Digital technology for optimized measures
Applications
 Urban wastewater treatment
 Industrial effluent treatment \
 Surface water monitoring
 Drinking water
 Sea water
The “smart” Digital CS7 sensor stores calibration and history data
within the sensor. This allows you a “plug and play” system without
re-calibration. Thanks to the Universal Modbus RS485 protocol, the Digital
CS7 can be connected to all devices commonly used (Datalogger,
Controller, Automat, Remote System…)
