Application by System

Cooling Systems:  Different sensors could be applied to a cooling system, e.g. level sensor to make sure the coolant is on safe level, temperature sensor to avoid coolant overheating.
Hydraulic Systems:  Hydraulic systems are widely used on devices like excavtor and cranes. Pressure sensors are utilized to provide feedback to control the movement, holding etc., they are also used to monitor the applied force to avoid any unsafe operation.
Lubricating System:  Flow sensors are used in lubrication system to monitor and control the lubricant flow. Pressure sensors are utilized to monitor the pressure of lubrication system.
Process Control:  Sensors are one of the key elements in process control system for quality control, efficiency improvements etc.
