Limit Switch Monitors Air Flow & Temperature

When drying any material in an air stream you want to make sure everything is flowing. One of our manufacturers utilizes a TC High limit temperature control to make sure everything is on the move.

High Limit Switch Senses Rapid Increase in Dryer TemperatureHigh Limit Switch

An example they used was if the grain they are drying builds up and blocks the flow the temperature in the shaft increases rapidly. By presetting the TC they can insert it in multiple spots along the dryer to keep a check on the system. If the TC senses the rapid increase in temperature beyond the set point it automatically shuts the system down. The manual reset makes sure the system can’t be restarted until the blockage can be cleared.

The adjustable models make changing temperatures as easy as loosening a screw and moving a dial. The sensing probe length varies depending on the width of the duct: 5″, 7.5″, or 11″. And the tough metal case protects the switch in rough environments. This is a cost effective solution to a big problem.
