New javelins with temperature and humidity measurement

We recently discussed the convenience of installing wireless javelin probes in warehouses for four main reasons: they are cost-free to install, they are easy to use, they can be moved from one warehouse to another, and they are also scalable. In this way, you can verify the system in your facility before making a major investment. 

Responding to our customers’ requests and within our continuous improvement program, at Gescaser we have developed a new version of the javelin with more features. In addition to being wireless and measuring the temperature, the new version of the javelin incorporates a sensor capable of measuring the humidity of the cereal.

With these new javelins, the supervision tasks for the optimal conservation of cereal in warehouses are no longer based solely on temperature control, but rather can monitor both the temperature and the humidity of your stored cereal.

Thus, within optimal quality margins, the two values can be combined to determine the maximum storage period.

Generally speaking: the lower the moisture content, the higher the acceptable temperature..

Let’s see an example.

The period of 6 months can provide an example: grain quality will not be reduced after half a year if the grain moisture content is equal to 12.5% and the temperature is 25 °C [point C on graphic]. The second example for the same safe storage time of 6 months is: the grain moisture content equal to 17.5% and the temperature 5 °C [point D on graphic].

As you can see, the new javelins provide you with very valuable information on the status of your grain. And, the more information you collect, the more facilities you will have to keep the grain in optimal conditions.

Why are javelins the ideal system for grain warehouses?

After the harvest, a delicate process of grain storage begins. A stage that, if not managed properly, can reduce both quality and quantity of harvest grain. In order to avoid its deterioration, it is important to have an exhaustive control of the grain temperature and carefully monitor grain conditions. Javelins may just be the perfect tool.  

How can we help you?

We’re pleased to present this practical and versatile system, ideal for controlling cereal stored in both small and large warehouses: the javelins or wireless probes. 

What are these wireless javelins or probes?

Javelins or wireless probes are the most suitable device to measure the temperature of grains and cereals stored in warehouses. Its technology does not require initial installation and is totally compatible with Gescaser systems (it works with both the CTC+ and the new CTC lite system).

These javelins are made of fiberglass and have a stainless steel tip. In addition, thanks to their flexibility and small diameter, they are very easy to insert in the grain.

We offer wireless probes with different length and number of sensors, which can be adapted to the requirements and needs of every client.

How do they work?

The javelins can be inserted anywhere in the warehouse where the grain is located. They are very easy to handle and their installation cost is 0.

Four great advantages of javelins

If we compare them with other sophisticated systems, typically for silos and large facilities, wireless probes clearly have four advantageous characteristics for warehouses.

1. No installation cost

As already mentioned, its main advantage over other systems is that this type of wireless probe does not require any kind of civil work when installing.

2. Ease of use and handling

Javelins are very simple tools to handle and do not require prior technical knowledge. This feature is a great advantage, and it allows taking temperature readings with ease. In addition, it makes them very versatile: as you empty the warehouse, you can re-insert the javelins where there is still grain to get new measurements.

3. Mobility

Another advantage of javelins is their ease of transport. Wireless probes can be used interchangeably in other warehouses, without depending on any physical installation. This becomes a key point for clients who do not have their own or fixed warehouse and rent it depending on the harvest season.

4. Scalability

Very often, when we consider the possibility of incorporating a new technology, we may have doubts about its convenience or effectiveness. Will it work for us? Will it add value to our company?

Aware of this, at Gescaser we offer you the option of purchasing only one javelin, in addition to the controller and the software, to verify its effectiveness. In this way, you can verify the system in your facility before making a major investment.


Temperature control options

For reading the temperatures, one has two control options: the CTC lite app and the CTC+ system.

With the CTC lite app

If a sporadic inspection of your grain condition is sufficient for you, you can control temperatures manually through the CTC lite app.

With the app (available on both IOS and Android) you can obtain records of the temperature of the javelins every time you go to the warehouse.

With the CTC+ system

If, on the other hand, you require a more exhaustive control of the conditions of your grain, you can install the CTC+ system, which allows you to consult the temperature records at any time and from anywhere. This option provides you with more control and less dependency.

In addition, the CTC + system allows you to position the wireless probes with the drag&drop option. In this sense, you can move the javelins around the software screen and place them where they are actually inserted.
