What Pull Force Will Break A Flexible Single Lead Probe?

1.	What Pull Force Will Break A Flexible Single Lead Probe?
Answer» In solid application, media might cause down-pull forces on silo roofs. The silo ROOF MUST be ABLE to withstand the probe collapse load or at least the maximum probe tensile load. The tensile load depends on the silo size, material density, and the friction coefficient. Forces increase with the buried length, the silo and probe diameter. In CRITICAL cases, such as for products with a risk for build-up, it is better to use a 0.24 in (6 mm) probe. Depending on their position, forces on probes are generally two or ten TIMES greater on probes with tie-down than on probes with ballast weights.
