There are two connectors in each crate. 1 power (4 pin female) 1 signal (7 pin male) For the power connector, pin 1 is closed, 2 is common, 3 is hot and there is a ground. For the signal connector, 1 is positive and 2 is negative. It sends out a 4..20 mA isolated signal. The probes should NOT be in the process without power on them. Power units up for 2 days to stabilize. Then you need to calibrate to ambient conditions. Take Cover off electronics - Leave open for 30... Read More

Detailed Drying Equation According to the “Industrial Dryer Handbook” the wet bulb temperature is a key parameter in dryer control improvement. The following equation represents the correlation to product moisture and drying parameters: X=K*LN((T1-Tw)/(T2-Tw)) where,X= Product MoistureK = is a dryer constant dependent upon product being dried and dryer designT1 = Inlet TemperatureT2 = Outlet TemperatureTw = Wet Bulb Temperature In general, industrial dryers have not come equipped...
