‘Hydrogen Sulphide’
A Engineeringtalk guide
Start with the news release
ESAB offers flux-cored wires from
ESAB, which we summarised at the time by saying "OK Tubrod 15.14 is the latest generation of all position rutile, low-hydrogen flux-cored wires from ESAB. ".
Several months prior to that,
we featured the news release Gas sensor offers quick detection of H2S from
Detector Electronics (UK): "Detector Electronics has announced an NTMOS hydrogen sulphide (H2S) gas sensor that detects low H2S gas concentrations in five seconds or less while tolerating harsh environments. ".
In October 2008, we covered the news from Raytek Corp
- take a look at Thermalert TX sensors prevent gas explosions
which says: "Special models of the Raytek Thermalert TX online infrared sensors have been certified by PTB as intrinsically safe according to hazard class EEx ib IIC T4. ".
Take a look also at the news release from Sensornet, Fibre cable survives oilfield extremes,
as well as Certified motors offer proven safety from ABB Automation Tech (Drives and Motors),
and Students showcase product design from PTC - Parametric Technology (UK).
