  • Rugged Construction
  • SDI-12 for Versatility
  • Low Power Consumption

 


 

DESCRIPTION:

The Frost Depth Probe - Model 5450-00 is a highly accurate, low power, temperature sensor system for determining ground frost depth. The Frost Depth Probe assembly is installed vertically underground and provides highly accurate temperature readings at various depths below the road surface. The Frost Depth Probe's rugged design is ideal for long term deployment below the road surface for determining the frost depth.

The Frost Depth Probe communicates via the open-architecture SDI-12 data protocol. This allows the Frost Depth Probe to be connected to HSE's line of dataloggers and many other industry standard dataloggers and telemetry options.

The Frost Depth Probe is of one piece construction made out of polyurethane to prevent any water intrusion to the sensor elements. Energy conductive aluminum elements are positioned with the Frost Depth Probe's temperature sensors to provide accurate soil temperatures without transferring energy along the sensor probe.

The Frost Depth Probe is available in various configurations and can be customized for length and sensor intervals. A standard configuration provides 12 temperature elements encapsulated within a 5 foot Frost Depth Probe length. The temperature elements are positioned with 3 inch spacing for the first foot and 6 inch spacing thereafter.
