description OPI Grain Monitoring Silo System Overview
OPI Systems Inc. is a Canadian company based in Calgary, Alberta that specializes in grain storage monitoring technology for farm and commercial grain operations. The company manufactures temperature sensing cables, moisture sensors, aeration controllers, and grain management software designed to detect heating and moisture changes in stored grain. These monitoring systems are installed in grain bins and silos to help prevent spoilage and quality loss during long-term storage.
OPI's products are used in grain-producing regions including Canada, the United States, and Australia.
help OPI Grain Monitoring Silo System FAQ
Does an OPI grain monitoring system measure moisture directly inside the silo?
OPI offers moisture cables that combine temperature and relative-humidity readings to calculate the grain's equilibrium moisture content. These cables are supported by current OPI Blue, Integris and StorMax systems, although older hardware may require a firmware update.
How many OPI temperature cables does a grain bin need?
OPI's general guidance calls for one central cable in bins under 24 feet, or 7.3 meters, in diameter. Larger bins generally need three or more cables, but final placement must account for the bin manufacturer's structural limits and the stored grain.
Can OPI automatically run silo fans when grain conditions change?
OPI systems can integrate monitoring with automated aeration control rather than merely displaying cable temperatures. The controller uses configured grain and weather conditions to decide when fan operation can cool or dry the stored crop.
Will new OPI moisture cables work with an old RVS1 unit?
OPI states that its newer moisture cable is not compatible with the RVS1 RTU. Integris and StorMax installations may support the cable after the appropriate firmware upgrade, while OPI Blue hardware updates automatically.
