Ott PLS-C Pressure Level Sensor, Conductivity, 0 - 40 m, RS-485
Product Number: 63.038.001.9043Measurement Range EU
Interface
Overview
The Ott PLS-C measures water conductivity, level, and temperature in both surface and groundwater applications with a robust ceramic pressure cell and 4-electrode conductivity cell. Its extremely low power consumption makes it ideal for long-term deployment, particularly at solar powered measuring stations for ground-and surface waters.
Benefits
The robust ceramic pressure cell offers industry-leading accuracy and does not deform over time like membrane technology, providing long-term measurement stability
Ceramic pressure cell resistant to physical force (4 x burst pressure) and enclosure made of high-quality saltwater resistant steel for use in coastal environments.
Vented pressure probe, automatically compensates for changes in barometric pressure.
Built-in microcontroller – compensates for temperature effects and applies correction values for gravitational acceleration or water density.
Simple setup and connection to external dataloggers using SDI-12.
4-electrode conductivity cell.
