Should you inspect your silo level sensors?

 

Silo level sensors normally do not need much attention; However, a periodic maintenance inspection on your level indicators may be helpful to prevent any future mishaps. Fall might be a good time to check, especially in areas that will be really cold soon. Nobody enjoys climbing silos in "freezing" weather. 

Below is an example of a possible checklist for a plumb bob style level sensor.

 

Example Checklist for SiloPatrol® Level Sensor

The SiloPatrol® plumb bob level sensors do not require a lot of "messing" with. Therefore a regularly scheduled maintenance procedure for these units is not necessary. We do, however, recommend for optimum performance that the following things be checked and performed on the SiloPatrol from time to time. 

 

For the Wiper Seal & Brush:
* Ensure cable freely travels through the entire wiper seal assembly.
* Clean wiper seal and brush as needed (compressed air or a toothbrush or similar works great) or replace if excessively worn.
 

For the Cable:
* Ensure there are no kinks, bends, "fish hooks" and knots on the cable .
* Ensure the jacketing is not fraying or peeling off the cable. Replace as needed .
      

For the Rollers:
* The white rollers on the cable side of the SiloPatrol unit should spin in both directions freely.
* The black wheel should spin freely. Ensure that it is tight on its 'Z' axis. (You can't push the black wheel in and out a significant distance.)
Also, check the silicone tire in the measurement wheel for cracks or wear. Replace measurement wheel if worn.
 

For the Plumb Bob:
* Ensure the plumb bob is clean and securely attached to the cable.
* Verify that plumb bob attachment hardware is in good condition.
