Overview

The TempVue™50 is a high-precision digital water and soil temperature sensor that extends the high performance of the TempVue product line into the water. The TempVue 50 is a rugged and reliable sensor that exceeds United States Geological Survey (USGS) Office of Surface Water (OSW) specifications. The sensor is also plug-and-play with the Aspen ecosystem of Internet of Things (IoT) edge devices.

This featured product was part of the Aconcagua expedition to install a weather station on South America’s tallest peak. Learn more about the expedition on our Extreme Application Series: Aconcagua page.

Key Advantages

Rugged and Reliable
For years of scientific-grade water and soil temperature measurements

Technical Description

The TempVue 50 is a fully digital water temperature sensor that uses the latest silicon bandgap technology to provide the market's highest level of accuracy and repeatability. The all-digital design minimizes self-heating, reduces complexity, and can be used to measure scientific-grade temperatures in both water and soil. The measurement electronics are surge protected and environmentally sealed with a fully encapsulated Delrin™ housing to provide years of reliable measurements in all environments.

Benefits

  • Submersible and watertight sensor and cable
  • Highly accurate silicon sensor providing reliable and stable measurements in all conditions
  • Strong anchor loop to pull through conduit or secure to weights
  • Calibration certificate provided
  • Simplified installation and programming with SDI-12 outputs
  • Calibration information stored within the sensor and automatically applied to raw values to eliminate the need for coefficient calculations
  • Intelligent, digital sensor offering less complex wiring and fewer data logger channels
  • Compatible with all SDI-12 data loggers
