GAS DETECTION
which can cause both environmental and sustainability issues. With such a shortage of semiconductors globally, preventing product loss through VOC detection is an easy way to maintain supply chains. When accurately monitored by high
precision sensors, VOCs and gases used in the semiconductor industry do not need to be detrimental to human health. However, without consistent and accurate measurement, such as that provided by ION Science sensors, worker risk is significantly increased due to potential exposures to a variety of chemicals above safe concentrations for extended periods. The types of VOCs that workers could
potentially be exposed to include ethylene glycol, trichloroethylene, and xylene. There is also a potential risk of benzene and formaldehyde exposure because of certain processes. Even in lower concentrations these can pose significant health risks. Monitoring for VOCs and protecting the health of workers takes a high priority and is why clear guidelines for exposure are laid out and need to be accurately analysed by sensors. ION Science is renowned throughout the
industry as the PID sensor of choice for VOC monitoring by OEMs, and were recently awarded the Queen’s Award for Enterprise in Innovation for its range of MiniPID sensors.

sniffing out low voltage cable faults
without the need for complex and costly cable test equipment. With the Fault Sniffer 2, fault location can be carried out while the network is live and, in most cases without digging or drilling, which means that costs, disruption and inconvenience are minimised. Most cable faults result in
T
burning of the cable sheath and insulation and as the Fault Sniffer 2 detects the gases produced by this burning. A vacuum system sucks the gases into the instrument via a sensor rod, where they are analysed in real time and the results displayed as a graphical representation of combustion gas concentration. Dual sensor technology is used which allows the instrument to distinguish between combustion gases and other natural gases that may be present in the environment. To further increase the sensitivity of
the Fault Sniffer 2, an auxiliary vacuum pump backpack is available and, when this is used, almost all faults can be detected by the small amount of combustion gas that permeates through cracks in road surfaces and paving, which means that it is rarely necessary to drill holes as an aid to gas detection. “Customers who operate low voltage
cable networks told us they wanted a simple way of finding cable faults that didn’t involve costly equipment or specialist skills,” says Tony Walker, applications engineer of Megger. “The
he new Fault Sniffer 2 from Megger provides a simple yet effective way of locating faults on underground low voltage cable networks
Fault Sniffer 2 is our solution to this requirement. Of course, cable fault sniffing isn’t new, but our product takes it to a new level. It can detect gas escaping through the tiniest cracks or porosity and it discriminates very effectively against non- combustion gases. It’s small, light and easy to use; we’re confident that it will save network operators a lot of money, time and trouble.” The Fault Sniffer 2 is supplied as a
complete kit that, as well as the instrument itself, includes a multi-probe sensor, an EFi filter set, a charger for 230 V AC supplies and a charging lead for 12 V DC vehicle supplies. All items are contained in a robust protective case with a carrying strap. Optionally available is an extension set vacuum pump system contained in a convenient backpack.
