How the Equipment Manufacturers Can Help


Gas detection equipment is typically calibrated at the factory at the correct setting for market conditions. Information regarding the concentration of gas used should be available from the manufacturer, and this should be the first point of contact if you are uncertain regarding what standard to use for calibrating you instrument.

Advanced Total Lightning Sensor, the Latest in Precision Lightning Geolocation Technology


Vaisala (Finland) have introduced their new Advanced Total Lightning sensor, the LS7002, offering the latest in precision lightning technology. It is the fi rst, non-VHF, lightning detection sensor to detect Total Lightning and, at the same time, correctly differentiate between cloud and cloud-to-ground lightning. The sensor is designed to operate as part of a network to provide real-time data for operations focused on tracking cloud and cloud-to-ground lightning threats to ground-based and airborne assets. The sensor is suitable for meteorological and climatological measurements, as well as applications in aviation, telecommunications, power utility, defense and forestry.


The Vaisala LS7002 sensor detects low frequency (LF) electromagnetic signals generated by lightning. The sensor is designed with extremely precise geolocation capability, as well as industry-leading measurement accuracy of lightning strength and lightning type classifi cation. The LS7002 also offers calibrated lightning parameters, and the sensor does not require calibration during normal operations, which leads to cost savings without any operational breaks.

MDA Gas Detectors


An LS7002 network uses a patented combination of time-of-arrival and magnetic direction fi nding techniques to deliver superior detection effi ciency, optimal location accuracy, with excellent system redundancy, while still utilising fewer sensors - no other company provides this blend of cost effi ciency and scientifi cally validated best performance. Vaisala lightning technology means that a larger area of coverage can be monitored with fewer sensors, providing a detection system with lower lifetime network ownership costs than any other technology.

In addition, an effi cient, lightweight electronics module allows for easy installation and maintenance with stand-alone, rooftop and indoor electronic mounting options. When working in severe weather locations, the sensor electronics can be installed separate from antenna installation.


Whenever a new Vaisala lightning sensor is introduced, such as the LS7002, Vaisala also uses the opportunity to update its Total Lightning Processor (TLP). This processor is used within Vaisala’s lightning detection networks and is designed to provide data for a wide range of applications. The TLP allows users the fl exibility to select features that are best suited for their requirements. Licenses are available for the following TLP features, including: system and sensor performance monitoring; network performance mapping; as well as detection effi ciency (DE) and location accuracy (LA) projections. There is also an advanced lightning type classifi cation option for “burst” processing and advanced waveform parameters.


These features provide more effi cient network operations, stabilised performance, and deliver advanced information with regard to geolocated lightning events. The TLP100 Series processes data from Vaisala’s low frequency (LF) sensors delivering unmatched performance; detecting, characterising and classifying cloud pulses and cloud-to-ground strokes. The TLP200 Series processes data from both Vaisala’s LF and very high frequency (VHF) sensors providing Total Lightning Mapping solutions, including the full spatial extent of any lightning threat.


Nemoto Sensor Engineering Co. Ltd (Japan) has developed a catalytic gas sensor designed to continually monitor for excessive levels of carbon monoxide and hydrogen in the flues of residential water heating boilers. The NAP-79A sensor works with a special circuit which allows the sensor to work effectively and continuously across a very wide temperature range, up to 260ºC. The sensor can therefore be mounted directly in the flue.


In the event of a fault resulting in incomplete combustion caused by, for example, a partially blocked flue, higher levels of carbon monoxide (CO) and hydrogen (H2


) become present


in the flue. High levels of these gases in the flue is a potential safety hazard, and also indicates that the boiler is working at lower than normal efficiency. The NAP-79A works in conjunction with the software of the boiler to provide an alert when the levels of CO and H2


facilitate an automatic shutdown of the boiler and/or flag the owner that maintenance is required.


This technique is widely and successfully used by manufacturers of residential water heaters in Japan, and can now also be used in Europe to comply with the continuous monitoring aspects of European standards for water heating boilers.
