This weighing approach is quick to install, causes minimum downtime and is ideal as a retrofitted system. The Boss bolt-on sensor is a well-proven robust product consisting of a strain-gauged element encased in a protective housing. It bolts to a structural member of the silo and deflects under the changing load conditions to give a varying electrical output relative to the load. Bob Davies, general manager at Applied Measurements, says: "We assess the suitability of this method of measurement for each enquiry, including an on-site survey if required."
The first consideration is the available stress for the sensor to measure and this is broadly dependent on the load applied and the design of the supporting structure it is mounted on.
Bolt-on systems are more than adequate for the majority of vessel weighing or level monitoring systems, where accuracy in the order of 12% is acceptable.
The benefit of this system to any company with a need to weigh grain or other loose material is that, unlike radar and ultrasonic systems (both of which present a cross-contamination risk as holes must be drilled for mounting of equipment), the bolt-on product doesn't come into contact with the product at any stage.
