ラポールプラントエンジニアリング List of Products and Services

The "Detector OD-8" uses a sensor that changes resistance due to the penetration of oil or organic solvents, and by periodically monitoring the amount of resistance change, it can early detect leaks of oil or organic solvents and issue an alarm. The leak alarm can be individually set to two modes: short-term leak alarm mode and long-term leak alarm mode. In addition to leak alarms, this product can also issue alarms when a short circuit or open circuit occurs in the line connected to the sensor, or when the sensor reaches the end of its lifespan (fault). 【Features】 ■ Measures and stores the resistance value of the sensor line every 5 seconds ■ The leak alarm can be individually set to two modes: short-term leak alarm mode and long-term leak alarm mode ■ The detector can monitor up to two systems (channels) ■ The sensitivity of leak detection can be finely adjusted using the operation button on the detector itself *For more details, please refer to the PDF document or feel free to contact us.

• Other physicochemical equipment

The "Integrated Monitor LD-320" is a system capable of issuing alarms not only for leakage alerts but also when a short circuit or disconnection occurs on the lines connected to the sensors, or when the sensors reach the end of their lifespan. Abnormalities detected by each detector are communicated to the user through electrical and visual notifications from both the integrated monitor and the detectors. In addition, we offer products such as the "Leak Detection Sensor OD-X," which has the function to detect and notify oil or organic solvent leaks, and the "Leak Detection Sensor LDC-X," which is equipped to detect and notify liquid leaks. 【Product Lineup】 ■ Integrated Monitor LD-320 ■ Point Detection "Leak Detection Sensor OD-X" ■ Point Sensor ■ Line Detection "Leak Detection Sensor LDC-X" ■ Sensor Cable "DGD050/DGD060 (Waterproof Type)" *For more details, please refer to the PDF materials or feel free to contact us.

• Other security and surveillance systems

The "LeakLearn LDC-2" is a detection system that monitors the leakage of various liquids, including oils, organic solvents, water, acids, and alkaline solutions, along the line. It can determine both large and small leaks through two monitoring methods: a medium-speed mode that monitors changes in the capacitance of the sensor cable every minute, and a low-speed mode that monitors every hour. By monitoring the output signals from the detector, multiple systems can be centrally managed. 【Features】 - Fine sensitivity settings in 10pF increments - Continuous monitoring of abnormal conditions such as liquid leakage, short circuits, disconnections, and open circuits - Capable of detecting leaks from most liquids, including oils, organic solvents, water, acids, and alkalis, etc. *For more details, please download the PDF or contact us.
