Dual-System Oil & Air Pressure Alarm Sensor for King Long & Yutong Buses | P/N: QG201 / QG202
Product Description
Your First Line of Defense Against Critical System Failures.
A sudden loss of oil pressure can lead to catastrophic engine damage, while a drop in air pressure can compromise the entire brake system. This high-reliability Pressure Alarm Sensor, manufactured by Nanjing Dingguan Accessories Co., Ltd., is a vital component designed to protect the most critical systems in King Long and Yutong buses.
This sensor series acts as an essential early warning system. It continuously monitors system pressure and, if it falls below the safe operating threshold, instantly triggers an alarm on the dashboard, giving the driver crucial time to react.
Key Features:
- Vital System Monitoring: Available as two distinct models to safeguard your fleet:
- QG201: Monitors critical engine oil pressure to prevent engine seizure.
- QG202: Monitors air pressure for the pneumatic brake and suspension systems.
- Broad Compatibility: Engineered for seamless integration with both King Long and Yutong bus models.
- Instant Alert: Provides an immediate, life-saving warning to prevent costly repairs and ensure passenger safety.
- Durable Construction: Built to withstand constant pressure fluctuations and harsh engine bay environments for long-lasting, reliable performance.
As a direct manufacturer, we deliver superior quality at competitive prices. Protect your assets and prevent costly downtime.
