Extensometer 178 of Vishay Nobel was especially developed for the applications of level weighing and monitorings on existing or new silos of a few tons to several hundred tons.
Extensometer 178 is a gauge sensor of extensometry which transforms a mechanical deformation of the foot of the silo according to the weight into an electrical signal (mV/V) directly proportional to the load applied to the foot of the silo.
This sensor has many advantages:
Easily plantable on existing silos
No major modifications
Control nonintrusive level
Measuring accuracy from 1% to 4% of the Payload
Very good alternative to the traditional weighing of the silos
Directly exploitable signal of measurement by electronic standards for gauge sensors
Very Quality positive ratio/Price
