OTT PLS

Pressure transducer with integrated logger

pls

The OTT PLS measures water level, depth of 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.

Features

  • 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)

What's the Easiest and Quickest Way to Start Collecting Data and Access it Anywhere?

The Answer's in the Cloud.

eTracker is a cellular modem and "virtual" cloud-based data logger in one (meaning you don't need to install a separate data logger). Simply connect your sensor and a power source to eTracker and you're done. Configure (or reconfigure) anytime from any Internet-connected device, and use Stevens-Connect to retrieve your data, or forward it to your favorite software system.
