Sensor cables
The sensor cable hangs vertically inside the bin and provides Chester X1 with temperature (and optionally humidity) readings at multiple heights.
Choosing a length
A good rule of thumb is to choose a cable that ends roughly 60 cm (2 ft) above the floor when the bin is empty. The top of the cable should be supported with a strain relief at the roof so the bin’s contents do not pull the connectors apart during unloading.
| Bin diameter | Recommended sensor count |
|---|---|
| Up to 19 ft (5.8 m) | 1 cable, 6–8 sensors |
| 19 to 30 ft (5.8–9 m) | 2 cables, 6–8 sensors each |
| 30 ft and larger | 3+ cables in a triangular layout |
Installation tips
- Suspend the cable from a dedicated eye-bolt above the roof port — never from the controller itself.
- Keep the cable at least 30 cm away from the bin wall to read core temperatures, not the sun-warmed steel.
- Coil any extra slack at the top, outside the bin. Excess length inside the bin can stretch and break sensors during unloading.
- Label each cable’s connector if you run more than one — order matters in the dashboard’s heatmap view.
Compatibility
Chester X1 reads any standard GrainLink-compatible cable using the documented digital protocol. If you are migrating from another vendor, check the supported cables list before swapping.
