In the waste industry, the scale is more often than not the “company cash register.” If a scale is unreliable or inaccurate, customers could be over- or under-charged (both of which are bad for business). Lightening and water (condensation and moisture) have always been the enemies of scales and weighing equipment. HyTronics is a weighing system designed to keep the electronic components of scales away from harsh elements and resistant components.

Designed and manufactured by Canadian Scale, of Etobicoke, Ontario the scale is guaranteed to meet or exceed all requirements of Measurements Canada. The system works by using hydraulic load cells in the scale. When weight is applied to the scale, a pressure signal is produced through a 1/8-inch copper or stainless steel tube to a totalizer, which converts the hydraulic pulse into an electric output.

The totalizer is a low maintenance device, yet is highly sensitive and responsive to changing input pressures. It consists of a vertical stack of hydraulic pistons, a cylinder assembly, and a single electronic load cell; all mounted in a rigid stationary frame.

The load cells are the main component which provide corrosion protection from water, salt, oil, and other chemicals. With HyTronic load cells, grade 304 stainless steel is standard but grade 316 is available for extreme conditions. The load cell capacity is a key factor affecting durability. Higher capacity load cells can better handle shock loading and reaction forces. Hydraulic load cells have a capacity of 75 to 250,000 pounds. (Common low capacity cells have a 50,000-pound capacity.)

There are no electronic components in the scale, so it is ideal for hazardous and explosive environments (Class I, II, III and Division 1 and 2, as well as Groups A, B, C, D, E, F, and G). Emery Winslow has placed a ten-year warranty on the load cells against normal wear and tear and a life-time warranty against water or lightning damage.
