Products for the measure of chlorine, chlorine dioxide, chlorites, peracetic acid, hydrogen peroxide, ozone, bromine, iodine, permanganate and other oxidizing substances
Selective measure of oxidising substances is very difficult when the concentrations to be detected are very low or very high.
CLR has recently developed a self-cleaning cell, with low sample consumption, for selective and reliable measure of chlorine, chlorine dioxide, chlorites, peracetic acid, hydrogen peroxide, ozone, bromine, iodine, permanganate and other oxidizing substances at low concentrations (0-2000 ppb and 0-10 ppm) and at high concentrations (0-2000 ppm).
Other measuring cells, simple and reliable, suitable for reasonably clean waters, complete the line.
All the cells for oxidising substances measure are selective, linear, assure a long-term reliability and very low maintenance requirements.
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 Cl2, ClO2, ClO2-, O3, PAA, H2O2, Br2, I2, O3, KMnO4
. local indication of process temperature
. temperature compensation of the measure through dedicated algorithms,
. selectable measuring ranges
. polarisation voltage specific for each parameter to be measured,
. 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 both analysis and temperature values (TX-HMI)
. automatic thermo compensation of the measure via software through specific algorithms
. 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
