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 or explosion proof 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.

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.

ALVI – India in association with Gas Alarm Systems – Australia offer Fuel Leak Detection.Industrial processes where fuel oil is used and stored, it is imperative to integrate an efficient fuel leak detection system to continuously protect distribution lines or storage tanks from leakage. Most of the storage facilities in process industries, where spills are common, use bund as a part of spill containment system. Bund is a constructed retaining wall around storage providing a barrier to an unintended escape of material until remedial action is taken. It is best to detect the leak within the bund when the leak size is small avoiding further damage and expensive clean-up costs. Bunding is widely used in fuel oil storage. Fuel oil such as petrol, diesel, kerosene, etc being non-conductive in nature , to detect and sense the presence of leak is a special challenge. ALVI Technologies presents Fuel Leak Detection sensor JOLA OWE2/C that is designed to signal the presence of a non-conductive medium . For an effective and early fuel leak detection, positioning and selecting the sensors at a right measurement point is quite essential. Jola OWE2/C detectors are placed under the tanks or pipes on the bund floor. It can sense and detect the presence of a liquid layer of about 2 to 3 ml! Alarm activation is required to trigger further corrective action. JOLA OWE2/C must be used with Jola Leckmaster 101 switching relay module. The various operating status on the switching module are shown by coloured LEDs. Thus an early detection of spill/leakage can trigger timely countermeasures avoiding any further damage.
