161-1704 3-Pin Low Pressure Sensor
Buy OEM Cat® part 161-1704 Low Pressure Sensor for air system, fuel system, and other engine-related repairs.
Description
Cat low pressure sensors use capacitive or strain gauge-based technology to generate an output signal (analog or PWM (Pulse Width Modulation)) proportional to the applied pressure. Pressure sensors are available with a variety of electrical connector and process connection types.
Features
- Compact size
- Easy to install
- Can be used with integral connectors or a variety of harness lengths
Applications
- Low pressure sensors are mainly used in engine-related applications such as air systems, exhaust aftertreatment systems, fuel systems, and engine oil systems.
- Cat pressure sensors are application-specific sensors. Refer to your Operation and Maintenance Manual or contact MECHSC for more information.
