One of the fastest, most accurate, compact, and cost-effective solutions for detecting oil leaks will be introduced by Asin Vietnam in the article below.
Diesel fire pump oil leakage phenomenon
Diesel fire pumps are industrial pumps widely preferred for use in fire protection systems. These pumps operate using diesel fuel, allowing them to function efficiently and reliably under all conditions, especially during power outages.

In addition, this type of pump is also suitable for office buildings, high-rise apartments, industrial factories, fuel depots, warehouses, airports, hospitals, schools, and many other facilities.
During operation, diesel leakage may occur from the specialized pump system. This can reduce the operational efficiency of the fire protection system, compromise safety, and cause the system to no longer meet operational standards. In severe cases, leakage may even lead to fire or explosion hazards.
Accurate Oil Leak Detection Device – Absolute Safety
To address oil leakage issues as early as possible, consider the installation solution using the NCT oil leak detection alarm system.
NCT Oil Leak Detection Sensor – Detects Leakage from Just 1ml
With only 1ml of leaked oil, the NA03AA Oil Chemical Sensor can immediately detect the leakage and provide real-time alerts, while clearly identifying the leak location on the monitoring diagram.
Conventional leak detection sensors often require a large leakage amount—around 30%—before detecting a problem. In contrast, the NCT leak detection sensor requires only 5%. This demonstrates the exceptional sensitivity of the Oil Chemical Sensor, which is built using nano-carbon material technology.
In industrial operations, detecting incidents as early as possible greatly improves the effectiveness of damage control and corrective actions. Therefore, the NA03AA Oil Chemical Sensor performs exceptionally well in early detection and delivers more accurate alerts than conventional sensing devices.

In addition to reacting to diesel fuel, the NA03AA is also used to detect gasoline and kerosene leaks. The NCT NA03AA oil leak detection sensor is widely selected for installation in oil refineries, fuel storage facilities, and factories that operate gasoline- or diesel-powered equipment.
Operating Principle of the NCT Oil Leak Detection Sensor
The NCT hazardous chemical leak detection system operates with a simple yet highly effective and safe mechanism. When an oil leak is detected by the sensor, the signal is transmitted to the sensor controller. The signal is then forwarded to the main control panel for processing and alarm activation.
At the same time, warning notifications are sent to the facility’s monitoring systems such as PCs, control equipment (PLC, DCS systems), and warning lights. Please refer to the detailed diagram below.

Signals are transmitted through a wireless network, making the system extremely neat and convenient for installation.
The sensor is designed as a thin, flat film made from Nano Composite technology, allowing long-term reuse without any reduction in performance after repeated exposure and reaction to oil.

For diesel tanks used in diesel fire pump systems, the sensor installation position is arranged around the storage tank within a relatively compact area, helping optimize space and reduce installation costs.
