OTT PLS-C temperature/level/conductivity sensor

The OTT PLS-C unit provides basic water quality indicators by measuring water level, temperature and conductivity. The probe is suitable for measuring both surface water and groundwater, with its high-quality and robust equipment ensuring easy operation and long-term precise readings. Low power consumption makes the product suitable for long-term deployment, particularly at solar-powered measuring stations.

The precise ceramic capacitive pressure cell withstands mechanical impacts and aggressive media. It is also stable over the long term, virtually drift-free and protected against overloads of up to at least four times its measuring range. Influencing factors such as temperature or changes in atmospheric pressure are compensated so that the probe provides precise water-level data.

For conductivity measurement, a four-graphite electrode measuring cell is incorporated. It is unaffected by polarisation effects and immune to any contamination. With its sealed-in waterproof electronics, saltwater-resistant stainless steel housing and Kevlar-reinforced longitudinally stable probe cable, the unit can also be deployed in harsh operating conditions.

The Windows-based operation software makes it easy to calibrate the conductivity cell and step-by-step instructions guide the inexperienced user safely through the process. Flexible connection options, available for communication by PC, make it easier to handle.

The SDI-12 interface enables the probe to be connected to any SDI-12 compatible data logger. When longer distance communication is required, the RS485 interface allows cable lengths of up to 1000 m when used with an OTT data logger.
