FAQs
What is a UniCond conductivity sensor?
A UniCond conductivity sensor is a special type of digital conductivity sensor designed for conductivity and resistivity monitoring in water systems. UniCond sensors come in a wide range of different process connections and wetted materials. All UniCond conductivity sensors have a built-in, integrated circuit that provides a digital output.
What is the advantage of a UniCond conductivity sensor?
UniCond conductivity sensors contain both the physical sensor and the measuring circuit in a single, compact unit. The main advantage with an integrated sensor and measuring circuit is that the wiring distance from the sensor’s electrodes to the measuring circuit is reduced to less than 5 cm (2 in.) and is fixed in place without using connectors or terminals. This is in contrast to traditional installations which must handle various lengths of analog signal cable, typically from 5 to 50 m from sensor to transmitter with terminations on at least one end. This integrated digital circuit also allows the UniCond sensor to be used across a wide range of conductivity concentrations, from pure water to brackish water.
How do I set up a UniCond conductivity sensor?
All UniCond sensors are factory calibrated. Furthermore, UniCond conductivity sensors carry their own identification and calibration data. When connected to an ISM transmitter, this data is automatically uploaded and the transmitter configures itself automatically without any operator intervention. The factory calibration of the complete measurement system is unaltered at installation, so factory accuracy can always be achieved in the field.
