Toroidal Conductivity Controllers
The Walchem Electrodeless Conductivity Controllers measure conductivity of a solution via an encapsulated, non-contacting sensor to control replenishment pumps and alarms.
They may be installed in a variety of very harsh chemical control applications, including oily cleaner baths, chromates, rinse tanks, fume scrubbers and other concentrated chemicals up to a conductivity of 1000 mS/cm.
Several conductivity ranges may be selected to configure the controller over a wide range of applications.
PEEK sensors for higher temperature, more aggressive chemical applications, or CPVC sensors for lower temperature, less aggressive chemical applications
Both available for in-line or submersible applicationsControls / Monitors baths with control and alarm relay for each
Time proportional and control option selectable on front panel keypad
Varies the pump or valve on time depending on deviation from set pointMonitor performance without taking the unit off-line, permitting faster troubleshooting and less downtime
Choice of measurement units in µS/cm, mS/cm, ppm or % concentration
% Concentration allows the user to enter up to 5 calibration data pointsUSB Flashstick Support standard for data logs, event/relay and reset logs, and user configuration file import/export
