8 GAS DETECTION New EX remote camera for monitoring hazardous areas


Meteor Communications has launched the MCE-MRC-EX camera, which is ATEX approved for use in Zone 1 & 2 hazardous areas. “Hundreds of our cameras are currently in operation all over the UK; helping to monitor and protect remote assets such as grilles, screens, channels, culverts and drains,” explains Meteor MD Matt Dibbs. “However, many of our customers in the water, waste, construction, rail and aviation sectors need to also monitor hazardous areas, so the MCE-MRC-EX camera was developed specifi cally to meet that requirement.”


Zone 1 & 2 hazardous areas are those in which there is a risk from the accumulation of an explosive gas. Typical locations therefore include confi ned spaces where there is a source of gases such as methane or petrochemicals, so the main applications for the MCE-MRC-EX camera will be in sewage and wastewater infrastructure, as well as in underground assets such as drains, culverts and pumping stations. Remote cameras can now be deployed in these locations to provide remote visibility of threats such as fl ooding.


The new camera is housed in an IP66 Ex-rated enclosure and an inbuilt IR or white light illuminator provides excellent low-light performance for clear, crisp images in any conditions. Images are transferred in real time via 4G with 3G/GPRS fallback, providing robust image transfer even from areas with poor mobile coverage. Images are sent to the ‘Meteor Cloud’ for secure viewing and analysis online, and there are options for those users wishing to integrate the images with their own applications.


The main advantage of remote cameras is that users are able to view sites remotely before deciding whether a visit is necessary, and also to determine what resources would be necessary for that visit. This means that less site visits are necessary, and wireless connectivity also means that operations such as camera confi guration and fi rmware updates can be conducted remotely.


Importantly, all Meteor cameras allow direct connection of local sensors such as level switches and PIR sensors. Images can be delivered at scheduled intervals and be confi gured to trigger automatically from local sensors; providing additional images and alerts to users and entering enhanced polling modes.


Summarising, Matt Dibbs says: “The MCE-MRC-EX remote camera has a very low power requirement, whilst delivering high-quality, real-time images from remote assets within Zone 1 & 2 hazardous areas where data and mains power connections may not be available.”

Upgraded MIPEX-02 with power consumption less than 1 mW


MIPEX-02 two-beam NDIR optical sensors family is well known for its low power consumption. Many manufacturers use it in their designs to provide longer battery life. Upgraded version offers advantage of 300 µA average operating current in standard fourth series form factor keeping untouched metrological performance of initial version. This is the only choice in the market.


Instruments utilizing older MIPEX-02 can use upgraded model without any expenses to adopt it as sensor keeps the same interface and intrinsically safe sensor circuit parameters.


Upgraded models can be used to measure concentrations of methane, propane and heavier hydrocarbons as well as carbon dioxide. If you need more information or want to order samples mail to info@mipex-tech.com

NevadaNano recently launched the “MPS™ Mini”, a miniaturised version of their highly successful Molecular Property Spectrometer™ (MPS™) Flammable Gas Sensor. According to NevadaNano, the new sensor is the world’s most accurate hydrocarbon sensor in its class and eliminates the need for maintenance during its 10+year lifetime.


“We have extended our market-leading reliability, accuracy, and lifetime with enhanced algorithms which extends our market-leading position of detecting 19 of the most common combustible gases found in residential, commercial, and other general use environments,” said Ralph Whitten, President, and Member of the Board of Directors, at NevadaNano. “This new product in a lower cost package specifi cally targets IoT and high volume applications. This enables our customers to set new standards in connected gas sensors and helps companies create safer working environments in industrial, commercial and consumer applications.”


The newest addition to NevadaNano’s MPS Product family, the MPS Mini Flammable gas sensor measures the thermodynamic properties of the air-gas mix and accurately reports 0-100% LEL across 19 fl ammable gases without the need for fi eld calibration. This performance meets the need for fl exible sensor platforms in a wide range of non-industrial applications and makes it ideal for residential and commercial applications like smart meters and IoT devices. In essence, the Mini Flammable creates safer environments for people and their surrounding communities.


Integrated, real-time measurements and built-in compensation for temperature, pressure, and humidity enhance the accuracy of all NevadaNano’s MPS fl ammable gas sensors. Gas concentration readings are accurate across the entire environmental range, including rapid environmental transients, delivering best-in-class accuracy. The Mini Flammable, like all MPS sensors, is inherently immune to drift, decay, or poison.
