Grain-Watch Temperature Monitoring Cables
The Grain-Watch temperature monitoring cables are fitted with our high quality digital sensors and
innovative 2-wire system. Our grain temperature monitoring cables were developed to be part of one of the most versatile,
reliable and accurate grain temperature monitoring systems on the world market. They can be mounted in customer-built floor
moulds, roof consoles, pipe sockets or brackets. Our high quality digital sensors remain calibration- and maintenance-free for
years on end. (In contrast, temperature cables with double thermo-elements, diodes or resistors need yearly calibration and
maintenance due to sensor drift. This takes time and costs you money.)
The Grain-Watch temperature cables are available in two diameters: 9.8 mm (3/8") and 17.0 mm (11/16").

Accurate grain temperature monitoring in big silo bins requires a number of temperature monitoring cables
in each bin. As a rule of thumb, one cable monitors a radius of 4 meters (13').
