About Us

The Grain Temp Guard Humidity-Temperature system is ideal for monitoring higher moisture grains or grain you are conditioning. Track grain conditioning with the humidity reading and data charts from our resources page. High and low temp/humidity warnings may be set independently on each function. Audible and visual alarm sounds when detecting changes in target temperature/humidity. The Grain Temp Guard Dual Temperature System is ideal for monitoring conditioned grains. Measure temperature in two distinct locations. High and low temp warnings may be set independently on each probe.

Grain Temp Guard

  • Sealed poly case with polycarbonate clear cover for easy visualization
  • Easy to open latch style cover for setting
  • 110 V external power with internal battery backup
  • Visual and audio alarm on a 10 m cord for mounting in a more accessible area
  • 15m Probes come standard with the unit
  • Additional probe lengths available: 10 m, 15 m, 25 m, 30 m and 45 m
  • Monitor temperature and humidity at one location in the grain bin
  • A must-have for conditioning grain (utilizing fans to lower grain moisture)
  • Trigger visual and audio alarm based on a high and low trigger point set by the operator for temperature and humidity

Over-drying corn or beans reduce your product by 1 1/2% for each 1% moisture loss.

Based on current prices, in a 30,000 bushel bin this costs:

$1650 for corn

$3850 for beans

Money spent to put an alarm HT probe in the top  (this can be placed after the bin is full) of the bin and one in the bottom would go a long way to help a farmer get control of this.

Recommendations for the number of probes to consider for your bin

Recommended: 2 probes per bin for the first 10,000 to 20,000 bushels and 1 additional probe for each additional 10,000 to 15,000 bushels. This will allow you to monitor more layers through the bin.

When using the Alarm HT (the correct unit for monitoring bins in which you are doing in bin drying or for monitoring soybeans) you will need to purchase twice as many units because this device has only 1 cable per monitoring unit. It is using its function to monitor both temperature and humidity (humidity is the key to providing the best grain moisture solution).

Did you know?

It's not too late to score all of your points in the EndZone!

Got 10,000 bushels of 9% beans? End zone can make you up to $6000 by helping you to rehydrate your soybeans  to 13%. The bins already full, no problem .  We have a system that allows us to get a probe into your bulkhead door and another monitor probe in the top of the bin, to allow differential moisture measurements. Talk to the folks at Farm Shop MFG to learn more 712-219-0148.

Producers may want to recondition soybeans harvested at lower moisture contents to bring the moisture up to the market standard of 13%. On a 40-bushel-per-acre yield, harvesting soybeans at 9% moisture content, rather than 13%, is equal to 1.8 bushels of lost weight per acre. At $9 per bushel, that is $16.20 per acre.

Just as grain is dried with bin fans, soybeans can be reconditioned by operating fans during periods with the desired air temperature and relative humidity. Reconditioning requires high airflow rates for several weeks using air with an average relative humidity of about 70% to recondition soybeans to 13% during normal fall temperatures of 30°F to 60°F.

Installing Grain Temp Guard

  1. Identify the location on the bin where you would like to position the unit. Do not position the unit in a location on the south or southwest side of the bin where afternoon sun will shine directly at the electronics (direct sunshine into the polycarbonate clear cover will result in a greenhouse type solar heating and can increase the internal temperature by 35°F to 50°F as compared to outside environment, thereby damaging the electronics). If you position the unit on the south or southwest side, it needs to be in a shaded area. Failure to do this will damage the LED screen and void the warranty. Additionally, you may want to consider an area in proximity to the internal ladder, as we normally use this structure to zip tie the cable to. Any loose cable on the outside the bin needs to be zip tied to a structure such as conduit, ladder rails, etc. to prevent wind whipping and chafing of the insulation. It is not recommended that you have long lengths of exposed cable on the outside of the bin. If this is necessary, it is recommended that you place the cable inside a conduit.
  2. Mount the case to the bin;  mounting flanges may be adjusted for the best match to a corrugation rib. Remove the gasket from the self-tapping screws, insert the screw through the flanged hole and replace the gasket. The gasket needs to be against the bin to prevent leakage.
  3. The probe will require a three-quarter inch hole through the corrugation. 
  4. Suspend any loose cable within the bin by zip tying it frequently to conduit or sliding it through conduit.
  5. A short arm can be made to suspend  the lower cable 36 to 48 inches from the ladder by bending a piece of re-rod into an L and positioning the long leg inside a ladder angle iron in the short leg sticking out no more than a foot. Too long of a lever will be ripped off by corn pressure. The long leg should pass behind two ladder rungs and in front of the third (see above graphic) to ensure the mechanism functions properly.  Zip tie the long leg of the L frequently or bolt it to ensure strength.
  6. Zip tie short cable to the L and zip tie any excess cable in a loop firmly to the ladder structure.
  7. Extend the long cable up along the ladder making a small loop of the excess cable and securing it to the top of the ladder or on a hook just below the access hatch. When the bin is full you will take this cable, uncoil it and position it in the grain where you would like to monitor the temperature or temperature – humidity.

The intent of this installation is to keep everything simple and cost-effective. You may at your own discretion provide a more complexed installation.

Why Grain Temp Guard?

Print

Because grain is a good insulator, the center of the grain bin retains heat longer. Moisture migration is caused by differences in grain temperature within the bin. In the fall, the cold air on the outside of the bin moves the warmer air inward and eventually upward to the top of the bin. It encounters the cold air at the top of the bin and causes condensation and crusting at the top of the grain. In the spring and summer, the opposite is true and condensation and spoilage occur at the bottom of the bin. Temperature monitoring helps maintain even temperature, preventing moisture migration.

Introducing our Unbeatable Closeout Prices for the Revolutionary First Generation Grain Temp Guards!

We are thrilled to announce that we have recently upgraded our Grain Temp Guard lineup with the next generation of bin monitors. To make room for these cutting-edge models, we are offering unbeatable closeout prices on our first-generation units.

What sets the first generation apart? These Grain Temp Guards boast an impressive error rate of just 2% in their readings. However, with our new and improved next-generation models achieving an even lower error rate of 1%, we are eager to clear out our remaining first-generation stock.

Not sure which model to order? Our Grain Temp Guards are available in two variants:

  1. Dual Temp (DT): This model is equipped with probes strategically placed at two locations within your grain bin. By monitoring temperature variations across your grain, it provides valuable insights into potential hot spots.

  1. Humidity Temp (HT): With a single probe placed at a specific location in your bin, this model allows you to monitor both temperature change and humidity levels at that particular spot, tracking moisture and moisture migration in your bin.


The Grain Temp Guard is ideal for bins with a capacity of 20,000 bushels or less. If you have a larger bin, simply purchase an additional probe for every additional 10,000 bushels to ensure comprehensive monitoring.

For enhanced grain monitoring capabilities, consider bundling multiple DT and HT systems. This will unlock a host of benefits and elevate your grain monitoring plan to new heights.

The Grain Temp Guard system gives you valuable knowledge about your grain bin, enabling you to develop a personalized monitoring plan. Say goodbye to waiting until it’s too late to address issues. Stay proactive by detecting problems early and safeguard your grain effectively.
