The Value of Bolt-On Sensors

Posted by Kistler-Morse on Oct 5, 2015 12:00:00 AM

Bolt-Ons are small strain gauge sensors that attach to the legs of a silo (or other type of beam support structure) and measure the stress level changes in the vessel's supports caused by material movement.


When the strain gauge sensors are bolted on to the support structure of the vessel, it converts the vessel into a weighing system. Adding weight to a  vessel compresses the gauge, changing the sensor's resistance, which produces an electrical output proportional to the material weight change.


Bolt-on technology uses the vessel's existing structure - there is no need to empty the vessel or take the vessel out of production. There are no specialized tools needed for the installation of the strain gauge sensors. Learn more about bolt-on quantity and placement here.


Because the existing vessel is used, there is no need to spend money on vessel modification.

How do you know if bolt-on sensors are right for your application?

Part of determining if bolt-on strain gauge sensors are appropriate for an application is the PSI value (or stress level). Kistler-Morse has developed a tool to help you determine if the PSI value required for bolt-on sensors exists in your application. The calculator includes three vessel scenarios - Leg Supported, Horizontal Beam and Skirted Silo. Click below to download the PSI Calculator!
