Factory Directly Sell  Air Pressure Sensor Switch DZ97189711201 for Shacman Truck Spare Parts

1. High Temperature Resistance: Capable of withstanding high temperatures up to 105℃, adapting to harsh working conditions around the engine compartment.

2. Standard Interface: Employs an M12 × 1.5 threaded interface with a standard 3 pin connector, ensuring easy installation and stable data transmission.

3. Interference Resistance: Internally precisely calibrated for excellent vibration immunity, ensuring stable pressure readings even on bumpy roads.

4. Precise Signal: Typically outputs a proportional voltage signal of 0.5-4.5V, enabling real-time and accurate monitoring of pressure changes.

This sensor is widely used in Shacman Delong series heavy-duty trucks, primarily installed near the air reservoir or brake master cylinder:

• Applicable models: Shacman Delong X3000, M3000, and M3000, F3000, F2000, L3000, and H3000, etc.

• Main uses:

Monitoring brake system air pressure: Triggers the instrument panel warning light when the air pressure falls below the safety threshold.

Feedback instrument readings: Displays the air pressure signal in real-time on the air pressure gauge in front of the driver.

During repair or replacement, the following related components are typically involved:

1. Sealing rings: Rubber or copper gaskets used to seal the mounting threads to prevent air leakage.

2. Sensor plug，wiring harness: The 3-pin waterproof connector that connects to the sensor. Check for corrosion or looseness in the connector.

3. Related valve bodies: Such as brake master cylinders, relay valves, four-circuit protection valves, etc. Sensors are often mounted on these components.

4. Alternative reference number: Some versions may correspond to OE number 3757010-2000-C00.
