How Many PGA Moisture & Temperature Cables do I need for my bin?

temperature and moisture cables

When it comes to ensuring your grain is stored safely, moisture and temperature monitoring is key, especially with grain bin moisture sensors. At Thunderstruck Ag, we recommend PGA Moisture & Temperature Cables to help you keep your grain in peak condition during storage. Figuring out how many cables you need for your bin can be tough. We ask four simple questions to guide you to the right setup.

1. What is the Diameter of Your Bin?

This is the first and most important question because the bin’s diameter dictates how many cables are needed for effective coverage:

  • 24’ Diameter Bins: You only need one cable. For bins this size, a single cable in the center can monitor both moisture and temperature adequately.
  • 36’ to 40’ Diameter Bins: You’ll need four cables. Place one in the center for moisture and temperature monitoring, and three around the radius to monitor temperature. This setup ensures you’re tracking both core and outer conditions.
  • 41’ to 47’ Diameter Bins: We recommend five cables —one in the center for moisture and temperature, and four on the radius for temperature monitoring. It’s important to note that at this size, you may need roof brackets to prevent any pooling on the roof, and ensure proper cable installation. Each cable comes with a floor bracket to anchor it at the bottom of the bin.

2. Is Your Bin Flat Bottom or Hopper Bottom?

Flat bottom and hopper bottom bins have different airflow patterns and moisture tendencies. Knowing the type helps us determine the cable placement and the type of brackets needed to secure them.

  • Flat Bottom Bins: Typically have even distribution, but can trap moisture at the base. Placing the cables strategically ensures you’re catching those spots where moisture might build up.
  • Hopper Bottom Bins: Moisture can move more quickly to the bottom in these bins, so we ensure that the cables are positioned to track this movement effectively.

3. What is the Side Wall (Vertical Wall) Height?

The height of your bin’s vertical walls will determine how long the cables need to be. Taller bins require longer cables to ensure proper monitoring from top to bottom. This also affects how we install the cables to maximize their efficiency.

4. What is the Total Height from Peak to Bottom?

Knowing the total height of your bin allows us to get the right length for your cables. Whether you’re storing grain to the very top or leaving a bit of space, having the proper length ensures you get an accurate reading throughout the bin.

Why Ask These Questions?

By asking these four questions, we can tailor the moisture and temperature sensors/cables setup to your exact needs. No two bins are exactly the same, and it’s important to get the right system in place to protect your grain. 

Whether you’re working with a smaller 24’ bin or a massive 47’ bin, PGA Moisture & Temperature Cables give you the real-time data you need to make informed decisions about your grain storage. Don’t let moisture or temperature fluctuations catch you off guard—protect your investment with the right tools & the right grain bin moisture sensors.

With the right number of cables, installed properly, you can take control of your grain storage and reduce the risk of spoilage. Start by answering these four key questions: the diameter, the bottom type, the side wall height, and the total height from peak to bottom. From there, we can help you get set up with the PGA Moisture & Temperature Cables you need to protect your grain from the top of the bin to the bottom.
