OPI Grain Moisture and Temperature Cable

Compatible with all OPI digital solutions, the OPI moisture cable is a valuable tool for an advanced grain management system. Monitor temperature, humidity, and grain moisture content throughout the bin to manage all in-bin drying and conditioning applications. Combine temperature and moisture data with automated fan/heater control to condition your grain systems efficiently and effectively for moisture control and accuracy.

Our new moisture cable has standardized sensor spacing of 4 ft. (1.2 m) for on farm applications and 6 ft. (1.8 m) for commercial applications. The cables can be built to meet a storage application range up to 130 ft. (39 m). Each moisture cable has both temperature and relative humidity sensors that are encapsulated in the cable to protect it from dust and contamination. In addition, each sensor measures the relative humidity and temperature in the airspace around the grain. We can calculate grain moisture content with a high degree of accuracy.

OPI Temperature Cables

OPI Stormax Temperature Cables

The OPI Temperature cable leverages industry-leading digital technology to record and provide vital grain condition data to your OPI Grain Management systems. Based on bin size, one or more temperature cables are installed, typically with sensors at 4′ or 6′ spacing throughout the bin.  OPI Temperature Cables are available in three sizes Medium Duty, Commercial Duty and Heavy Duty. What makes the temperature cable so unique is our exclusive retractable sensing element, which is protected inside a sturdy outer tube. This unique design combined with digital technology provides multiple benefits including:
