Ott PLS Pressure Level Sensor, 0 - 40 m, 4 - 20 mA
Product Number: 63.037.001.90B3Measurement Range EU
Interface
Overview
The Ott PLS measures water level, depth to water, or pressure by means of an integrated controller and ceramic pressure-measuring cell. Design features such as multiple communication outputs (SDI-12 or 4-20 mA), stainless steel housing, and a rugged cable make this sensor ideal for monitoring water level in a variety of applications.
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 (5 x burst pressure) and enclosure made of high-quality saltwater resistant steel for use in coastal environments.
Built-in microcontroller – compensates for temperature effects and applies correction values for gravitational acceleration and water density.
Vented pressure probe, automatically compensates for changes in barometric pressure.
Simple setup and connection to external dataloggers using SDI-12 or 4-20 mA interfaces.
Water temperature output in addition to water level (for SDI-12 output).
