PNEG-707 12', 18', 24' and 30' GSI Commercial Tower Dryer 107
Grain Temperature Sensors (RTDs)
Install RTDs on outside of dryer, within safe reach of ladder.
There is one (1) RTD on a 10' length of 1/2" conduit.
Position RTDs according to Figure 8A on Page 97 . Drill hole in dryer wall for sensing bolt on each RTD.
Add one (1) 3/8" washer to bolt/washer already on each RTD. Insert sensing bolt in hole. Secure conduit
near RTD with 1/2" conduit hanger. Use existing bolts on seam.
NOTE: Do not place nut on inside of outside screen.
Placement of RTDs
Either RTD can be installed in top position.
R.H. Pair of RTDs
Install to right of outside ladder, and within reach of outside ladder.
Place R.H.-bottom RTD just above heat section floor.
R.H.-top RTD is on same conduit, 10' above bottom R.H. sensor.
L.H. Pair of RTDs
Install in next grain column over from R.H. pair of RTD, at the same level as R.H. pair, and within reach
of outside ladder.
Installing Conduit for RTDS
• Run conduit parallel or perpendicular to other conduits and dryer features.
• Vertical conduits should be plumb, neat, and orderly.
Figure 8V Grain sensor
is embedded in stainless steel bolt.
NOTE: Either RTD on conduit can be installed in top position.
