Grain Watch™ Temperature line – GWSL2100

Temperature line GWSL2100 is part of Grain Watch’s patented temperature monitoring system. All temperature lines are made of durable and conductive material to protect the digital sensors. This enables a thin and strong construction with minimal weight.

The GWSL2100 is developed for tall silos where the pressure on the stored material is extensive. Despite its ability to cope with high pressure, the diameter of the GWSL2100 is only 17.0 mm, which minimizes the roof load.

The sensors in the GWSL2100 are available as standard with 2-3 meter spacing. The length of the GWSL2100 is adapted for each individual installation.

No sensor calibration or maintenance is required. Quick and easy installation makes it easy to ensure monitoring of your grain.

Grain Watch temperature lines are hung in steel or concrete silos in different ways depending on the construction and the customer’s wishes as below.

Each sensor has a spherical coverage area of 6 meters. The number of temperature lines and placement are therefore dependent on the dimensions of the storage.
