The Amphenol NGM-1 Multiple Function Sensor Modules Low Power Natural Gas Module is a compact and powerful natural gas monitoring system. It contains two wireless sensor modules which allow for real-time gas concentration monitoring from distances up to 500 meter (individual signals take up to two seconds to reach the transmitter). The system is highly accurate and comes with a low power consumption enabling it to run for months on its own power. The natural gas module is constructed with 4-core sensor coils, temperature, pressure and humidity sensors, as well as of an MCU that handles all the input/output functions. The NGM-1 also features data encryption, off-site monitoring and alerts, allowing it to be easily connected to an external device or data logger. The user-friendly interface is designed to make the initial set up, monitoring and control easy and convenient. This product is ideal for use in applications involving natural or liquefied petroleum gas systems and is certified to CSA, UL, FCC and CE standards.
