Portable Grain Bin Monitor
My homemade, portable grain bin monitor is easy to see, day or night, and can be easily moved from bin to bin. It comes with a telescoping handle that supports a metal arm on top. A sensor suspended by a length of cable hangs from the arm inside the opening in the bin roof. The sensor has a built-in mercury switch. When grain contacts the sensor it automatically turns on a flashing light at the bottom of the handle. The distance the sensor hangs down into the bin can be adjusted by loosening a set screw and pulling the cable down or up. It's a simple, low-cost sensor that you can use on all bins. It also can be used to monitor the level in air seeder tanks and fertilizer tanks, etc. The flashing light is easy to see during the day.
  My friend Bev Pavo demonstrated the monitor at the recent Western Farm Progress Show in Regina, Sask. I'm looking for a manufacturer. (Ken Mann, Box 158, Dinsmore, Sask., Canada ph 306 856-4409)
