Digital Conductivity Sensors Monitor a Wide Range of Chemical Concentrations

Sept. 11, 2013
New four-electrode sensors have been designed to provide highly accurate measurement across a very wide range.

Mettler Toledo Thornton announces the expansion of its conductivity sensor portfolio with the UniCond 4-E digital sensors. 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 says it’s 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 guidelines.
