Gas Leak Detectors

Product Details:

PNG (Methane), chemically known as CH4 is highly flammable, lightweight gas with LEL at 5% Vol = 100% LEL. Methane gas detector series is highly robust, industrial grade, flameproof gas detector for methane leakage detection or LEL monitoring. Methane is also available in form as a natural gas, pressurized natural gas (PNG), liquefied natural gas (LNG). The detector is used for online, continuous monitoring of the flammable concentration of methane in %LEL or %Vol terms in ambient air or in duct or pipeline. It is ATEX, IECEX, PESO certified with SIL 2 safety integrity level for hazardous area installation Zone 1 and 2. The sensor transmitter offers linear, proportional analog output in industry standard current signals, over measuring a range of 0 ~ 100 % LEL (lower explosive limit). The detector works on highly sensitive catalytic bead-based pellistor sensor cell, with low response time. It has the unique feature of an auto diagnostic watchdog with zero point tracking feature. Due to its 12-bit microprocessor based control unit, it offers high accuracy over the long term. The detector is also equipped with a sintered filter with flashback arrestor for enhanced safety. It also offers optional features like inbuilt LCD display, flashing alarm LEDs, onboard potential free relay contacts (24VDC .1 A), RS485 serial interface with Modbus RTU communication.

All products and systems are manufactured in Germany, hence quality and reliability are assured.

Product Details:

The door-entry modules provide maximum safety in addition: If the gas concentration increases in closed buildings, for example in cooling rooms, the doors can only be opened in one direction: from the inside to the outside. This ensures that people can only move out of the hazardous area, but they can never move in. At Gas Alarm Systems, we develop and produce perfectly matched sensors, controllers and warning devices, which can be combined in many ways into high quality gas warning systems. Optimum protection for people and installation is thus ensured in enclosed areas in critical situations. Due to the individual configuration and the flexible integration, solutions our refrigerant leak detection system is used worldwide in a variety of applications.
