OTT – PLS Pressure Level Sensor

Description

OTT – PLS Pressure Level Sensor

Robust ceramic pressure transducer for water level measurement

• Application: Surface water, Groundwater
• Measurement technology: Vented pressure cell
• Parameters measured: Water level, Pressure, Temperature
• Product Highlights: Water level and temperature measurement – for use with external data logger
• Measurement range: 0 … 4, 10, 20, 40, and 100 m
• Accuracy: ± 0.05% FS
• Internal data logger:    No
• Interface: SDI-12, RS-485 (using SDI-12), or 4 … 20 mA
  

Advantages:

• The robust ceramic pressure cell offers industry-leading accuracy and does not deform over time like membrane technology, providing long-term measurement stability
• Rugged design: 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
• Robust cable with Kevlar core for length stabilization and capillary tube for venting
• Simple setup and connection to external dataloggers using SDI-12 or 4 … 20 mA interfaces
• Optimized resolution is achieved by assigning the 4 … 20 mA to that part of the measuring range that is actually required
• Water temperature output in addition to water level (for SDI-12 output)

 

Measuring water level in surface and groundwater, including:

• Stations with sloping bottom, e.g. water banks
• Small diameter pipes or holes (from 1″ Ø)
• Dams, weirs, irrigation systems
• Waterways that occasionally ice over
• Brackish water, saltwater
• Waterways that do not contain water throughout the year (e.g. retaining basins)
