Series 672 Low Pressure Transducer, is this pressure transmitter suitable for use with Natural Gas? The specs just mention 'suitable liquids and gases", but I don't see a list of what is suitable.
No, the 672 series low pressure transducer is not suitable for natural gas. It is not explosion proof nor compatible with combustible gases or liquids. As an alternative, depending on the range you need, I would recommend the 636, 3100, 3200G, or IS626 series pressure transmitters.
