About Pergam's LMS/LMS Mini
Autonomous Remote Natural Gas Monitoring System PERGAM is a leading manufacturer and supplier of remote leak detectors for the natural gas industry. Our technology is based on the principle of absorption infrared spectroscopy using a diode laser with tunable frequency. Together with our patented algorithm, it can determine the gas concentration. This allows remote and real-time gas leak audits; features that no other technology provides. Junior representative in the line of stationary Pergam scanners. LMS mini is designed to monitor leaks in small to medium sized areas. LMS Mini features:
- Fully autonomous scanning system
- Range — up to 656 yards (600 meters) (with retroreflector)
- Three-spectral design upon request (with IR module)
- Programmable facility scanning algorithm
- Can be installed anywhere using a telescopic mast
The area is scanned automatically with a programmed path. The system operator can see the facility scanning process on the monitor at the control panel visually in real time.
If a leak is detected along the scanning laser path, the system records this fact, gas concentration at the leak, leak coordinates and time.
System behavior at the time of leak detection can also be programmed — record data and continue scanning, send a message to the duty control panel, or stop scanning and turn on the alarm. These actions can vary depending on the threshold leakage concentration. LMS Specifications:

LMS Mini Laser Methane Detector FAQs
No, each device is designed to detect a specific gas. This provides a 100% probability of leak detection of methane and not any other gas.
Laser radiation is completely safe, it corresponds to class 1.
Yes. It is an active device, it emits at a certain narrow wavelength, so it does not need additional signal sources.
No, there is no impact.
No. The detector contains a reference container with methane inside and calibration is performed at each start-up and during operation.
It works remotely. There is no direct contact with the hazardous environment.
Direct range of the LMS laser detector is 492 feet (150 meters); 196 feet (60 meters) for LMS mini. This distance can be increased using special repeaters to 1093 yards (1,000 meters) and 656 yards (600 meters) respectively.
Yes, because glass transmits the near infrared radiation well.
LMS mini is ATEX and IECex certified. LMS is only available in a conventional enclosure without explosion protection.
