OPI Moisture and Temperature Cables
Compatible with all OPI systems, the OPI moisture cable is a valuable tool for your advanced grain management. Monitor grain temperature, humidity and grain moisture content throughout the bin to manage all in-bin drying and conditioning applications. Combine with automated fan control systems for the highest degree of moisture control and accuracy on the market.
Each sensor also includes a temperature sensor, so that temperature, relative humidity and moisture content can be read throughout the grain.
The OPI moisture cable has sensors placed on the cable—commonly at 4’ intervals in farm applications and 6’ intervals in commercial applications. Moisture cables are used in grain depths up to 85’. Each sensor consists of a relative humidity sensor encapsulated in a sintered filter that protects the sensor from dust and contamination while allowing for instantaneous readings. By measuring the relative humidity and temperature in the airspace around the grain, we are able to calculate grain moisture content with a high degree of accuracy.
