The
new four-electrode sensors have been designed to provide highly
accurate measurement across a very wide range: a single UniCond 4-E
measures from pure potable water to acid or base concentrations.
Applications
for the UniCond 4-E series include Clean-in-Place and desalination
processes, deionization regeneration, industrial processing, and
wastewater treatment.
Analog
conductivity sensors are prone to signal degradation caused by
sensor-to-transmitter cable resistance and capacitance. METTLER TOLEDO
Thornton has solved this issue by incorporating technology into the
UniCond sensors that converts the analog signal into a robust and
reliable digital signal. In addition, the sensors contain METTLER
TOLEDO's Intelligent Sensor Management (ISM?) concept.
Features of ISM include Plug and Measure start up at the measurement
point and sensor diagnostics for proactive maintenance. In addition, the
UniCond 4-E can be calibrated without extraction from the process. This
makes the sensors compliant with United States Pharmacopeia (USP)
guidelines.
