OTT Orpheus Mini

Pressure transducer with integrated logger

orpheus mini

The OTT Orpheus Mini has been designed for the reliable monitoring and storage of water level and temperature. The main application of the Orpheus Mini is the installation in ground water pipes and wells for groundwater monitoring. In addition, applications in open waters and tanks are possible.

OTT Orpheus Mini is equipped with a rugged, ceramic-capacitive measuring cell and a precise temperature sensor. A data logger, which can be configured individually, stores and manages the monitored measured values in a 4 MB non-volatile memory (corresponds to approx. 500,000 measured values). The power supply of the Orpheus Mini as well as the connection for downloading data and start-up are provided by the communication unit.

The infrared interface allows the data to be conveniently read out or transferred from the device with a laptop. A well structured, intuitive operating program with all the necessary functions for data output and export, configuration and calibration is supplied.

Features

  • Easy installation in observation wells of 1" diameter and larger by adapter plates or suspension bracket
  • Power supply can optionally be provided by Lithium or Alkaline batteries
  • The batteries can easily be changed on-site
  • Longitudinally stable pressure probe cable by Cevlar core
  • Potted, hermetically sealed pressure probe
  • Saltwater resistant casing material

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.
