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
