Linea Torbidita

Products for the measure of Turbidity

The measure of turbidity is typically used in wastewater treatment plants, drinking water plants, in food & beverage industry, in the breweries, in paper mills and in many other industries.
The turbidity sensors developed by CLR are nephelometric type, side scattering 90°, and are designed for through-flow, immersion and direct installation in pipeline; they can withstand different conditions of process temperature and pressure.

We can supply process instrument suitable for panel mounting and for in-field installation (IP65 protection degree):
among  these, the uP transmitter-indicator-controller  is available in two versions: the complete version uP and the light version uPLT.

Main features for both units:
. local indication of measured parameter
. power supply to the cell optical system
. isolated 4-20 mA output (not available in the uPLT version),
. 4 programmable digital control outputs (2 for the uPLT version),
. self diagnostic and sensor diagnostic functionality,
. capability to drive the cleaning sequence for the sensor.
. freely programmable linearization curves

In the same family the PID controller, suitable for panel mounting and for in-field installation (IP65 protection degree), has the same features of the uP transmitter, and additionally allows PID process control either through contact control output or analog control output.
The line now includes a transmitter-controller with RS485 serial interface and MODBUS RTU communication protocol, Mod.TX  and the Transmitter Indicator Controller c/w local keyboard and diplay Mod.TX-HMI.
Main features for these units:
. display indication of  analysis  values (TX-HMI)
. power supply to the cell optical system
. RS 485 serial interface with MODBUS RTU communication protocol
. 2 analog output 4-20 mA for measure and tempertaure
. 2 digital outputs from relay, programmable
. 2 digital inputs, programmable
. remote calibration capability
. isolated 24 Vdc power supply; 24 Vac power supply
. suitable for rear panel mounting (DIN bar)  and for outdoor installation (IP 65 protection degree)
. freely programmable linearization curves
