Индикатор впускного воздушного фильтра Caterpillar 5309191

An Air Inlet Filter Indicator provides visual feedback that reflects the level of air flow restriction within the air intake path. Its function is based on sensing changes in air movement and translating those changes into an observable signal that can be checked during operation. As air flow becomes restricted, the indicator response changes, allowing operators to identify when filter attention is required without interrupting operation.Attributes:• Provides visual indication of air flow restriction.• Supports monitoring of air intake conditions.• Allows restriction status to be checked visually.Applications: An Air Inlet Filter Indicator is used on the air intake system to display air flow restriction status and support timely filter service decisions during operation.
