Переключатель воздушного фильтра, 15 В Caterpillar 4488328

An Air Filter Switch generates an electrical signal or switch state change when the pressure drop exceeds a pre-determined threshold, indicating that the air filter requires servicing. This signal is then communicated to the engine's electronic control unit (ECU) or a dashboard warning light, alerting the operator to the need for air filter maintenance.Attributes:• Provided with voltage breakdown maximum 450 VDC to reduce the risk of electrical hazards• Provided with a storage temperature of a maximum of 150 degrees Celsius and minimum of -50 degrees Celsius• The switch opens when it reaches a vacuum pressure of 3.7 kPa Applications:An Air Filter Switch detects when the air filter has become clogged or obstructed, indicating that it needs to be serviced or replaced. It utilizes a pressure-sensing to monitor the differential pressure across the air filter.
