Description

The ORAKEL range of Conductivity sensors measure conductivity from 0 to 2,000,000 µS/cm2 (range selectable). You can choose between a standard graphite sensor and a more sophisticated toroidal sensor, or stainless steel ‘special’ sensors for high temperature, high pressure applications.

How it Works


Electrodes encourage microorganisms to grow on the surface of the probe before they would grow on the surfaces of a pipe or a vessel. The biological activity of the biofilm creates a signal. The controller collects and monitors that signal continually. An increasing trend in the signal indicates the onset of biofilm activity on the probe.

The controller can then take remedial action automatically by, for example, increasing or decreasing the biocide levels, triggering email or text alarms and data logging.

TDS

Total Dissolved Solids (TDS) and salinity are both measured with conductivity sensors, and the ORAKEL controllers can provide outputs and on screen displays of calculated TDS and salinity readings from the conductivity sensors. ORAKEL controllers come with standard user adjustable, factors for calculating TDS and salinity.

Applications

Graphite

Our light industrial conductivity sensor utilises Graphite technology. The durable epoxy body construction provides a rugged and dependable sensor for potable water and clean water. Mount them in-line, in a pipe “T” fitting, or submerse them into a tank. For many applications, the epoxy body conductivity sensors are the lowest cost, most reliable conductivity sensor to use, especially for process applications. Rugged epoxy bodies make the sensors virtually unbreakable. These are an excellent choice to use as standard online conductivity electrodes in the water and related industries.

Toroidal

The toroidal inductive conductivity sensors  feature a wide measurement range and dependable toroidal technology over the range 0-2,000,000 µS/cm2. Resistant to corrosion, coatings and fouling common to contacting conductivity sensors, this probe is designed for a trouble free and long service life. Noryl is the standard material of construction and has a wide solvent tolerance and temperature stability to 105ºC.  All models can be submersed by utilising the 3/4” MNPT threads on the sensor or installed in 2” NPT tees for in-line deployment. A temperature sensor is built into the conductivity sensor for automatic temperature compensation.
