Low pressure indicator

The indicator is a simple and inexpensive solution to monitoring tyre inflation pressures. The indicator is fixed on a valve. If inflation pressure of forestry tyre decreases by 0,6 bar the led indicator starts to flash. In forestry rims the valve is protected with metal and nylon parts. Metal part is a tube with thread welded to rim. The nylon cap can be threaded into metal part to cover and keep valve clean, free form dirt and water. Often the cap is black. This is replaced by a white transparent cork. When the inflation pressure drops below the warning level, a red LED light is
 
If the tyre pressure is too low, it puts a considerable strain on the tyre and in time will cause a puncture activated. After this alarm, the tyre should be inflated back to the recommended inflation pressure.
 
This simple solution means that tyre pressures will not fall without it being noticed. When pressures are all right, the contractor saves a significant amount of time and money by avoiding damage and harm to tyres.
