Rotronic is a leading Swiss manufacturer of precision Intrinsically Safe sensors and measurement transmitters with selectable analogue outputs, suitable for use wherever there is a risk of explosion due to dust or gas in the environment. They were developed for the pharmaceutical, biotechnology, grain & sugar, petrochemical, and oil & gas industries.
Conforming to the latest international standards, the Intrinsically Safe (secondary side) HygroFlex5-EX transmitters have two channel 4-20 mA outputs.
