At the core of grain storage, temperature and moisture need to be carefully managed to preserve quality and prevent spoilage. This is where our Grain Temp Guard Dual System can play an important role. By combining two alarm systems into one design, we are able to deliver flexibility that helps us meet different storage requirements.

The system allows operators to choose the right balance between temperature and humidity monitoring, depending on grain condition and bin size. 

Understanding the Grain Temp Guard Dual System

The grain temp guard dual system is built as a two-box arrangement that makes it possible to expand monitoring options. It can be configured in three different ways, depending on the needs of the storage setup. Two Alarm DT units can be installed in large bins to cover multiple probe points, ensuring temperature conditions are tracked with greater detail. Another configuration is one Alarm DT combined with one Alarm HT, which allows temperature probes to reach deep into the grain while humidity is monitored at the top.

A final option is two Alarm HT units, which monitor both temperature and humidity at the top and bottom, making them highly useful in in-bin drying situations. These flexible configurations allow the system to support a wide variety of grain conditions and bin capacities. 

Features of the Dual Temp (DT) Model

The Dual Temp model has been designed for focused temperature monitoring. Each unit is housed in a sealed poly case with a transparent cover and latch that protects the system while keeping it easy to access. Power is supplied externally through 110 V, while an internal battery serves as backup. A visual and audio alarm is connected through a long cord, which makes it easier to mount in a convenient location for operators. Standard probes are available at 15 meters, and additional lengths can be ordered to match bin size.

The DT system allows each probe to be programmed with high and low alarm thresholds, which can trigger alerts whenever temperature fronts shift through the stored grain. According to the farm shop Grain Temp Guard specifications, one DT unit can monitor up to 20,000 bushels, while two units can extend coverage to as much as 40,000 bushels. This makes the model suitable for dried grain that has already reached its target moisture content.

Features of the Humidity-Temperature (HT) Model

The HT model expands the monitoring capacity by including both temperature and humidity measurements in a single probe location. Like the DT, it comes in a sealed case with latch closure, external power backed by an internal battery, and a visual and audio alarm mounted on a cord. The key difference is that it can provide humidity readings in addition to temperature, which is critical when grain has higher moisture levels or when in-bin drying processes are taking place.

High and low thresholds can be set for both temperature and humidity, allowing alerts to be raised if either measurement moves outside of the acceptable range. The Grain Temp Guard HT model is particularly effective in mid-sized bins or in storage areas where moisture management plays a significant role. Because each HT unit monitors a single location, additional units may be needed to cover larger bins effectively.

Comparing the Dual System to Individual Models

The Dual System is valuable because it allows operators to combine DT and HT models in ways that suit their specific needs. For large bins holding dried grain, using two DT units ensures comprehensive temperature coverage with four probes installed in a single setup. In mid-sized bins where most of the grain is dry but some moisture may still be present, combining one DT and one HT provides an ideal balance between temperature monitoring and humidity tracking. For bins that are actively undergoing in-bin drying, two HT units offer the ability to monitor both humidity and temperature at the top and bottom of the grain mass.

This combination approach gives operators the opportunity to adapt their system to changing conditions, making the grain temp guard system a versatile solution for grain storage management.

Installation and Probe Coverage

Both DT and HT models share installation features that help make them reliable and consistent across different setups. Each unit is housed in a sealed poly case with a latch and transparent cover. Power is provided through an external 110 V connection, with an internal battery available for backup. Visual and audio alarms are mounted on cords, allowing them to be placed at accessible points around the bin. Probes come in standard 15-meter lengths, with options extending up to 45 meters to accommodate larger structures.

When it comes to coverage, two probes are recommended for bins storing between 10,000 and 20,000 bushels. An additional investigation should be added for every 10,000 to 15,000 bushels beyond that. A DT unit can cover up to 20,000 bushels on its own, and two DT units extend that range to 40,000 bushels. With HT units, multiple systems may be required in order to adequately cover larger bins, since each monitors only one location. 

Choosing the Right Model

The choice between DT, HT, or the Dual System depends on the condition of the grain and the purpose of the storage. DT models should be selected when dried grain is in storage, and temperature alone is the key indicator of changes. HT models should be installed when higher moisture grain is being stored or dried, because both humidity and temperature need to be closely tracked. The Dual System should be used when a combination of both monitoring methods is required, ensuring that larger bins or mixed conditions are fully managed.

Conclusion

The Grain Temp Guard Dual System has been created to provide flexible monitoring options for grain storage facilities of varying sizes and conditions. Its strength lies in the ability to combine two alarm systems, creating coverage that suits the exact needs of the operator.

The DT model is best applied to dried grain in storage, the HT model excels in higher moisture or drying scenarios, and the Dual System allows both approaches to work together for greater effectiveness. By selecting the proper configuration, operators can ensure that grain quality is preserved, spoilage is reduced, and storage outcomes remain consistent.
