New intrinsically safe HygroFlex5-EX series

New intrinsically safe HygroFlex5-EX series

Rotronic has launched a new transmitter for measurement of humidity and temperature in explosive atmospheres. The series is certified to ATEX and IECEx and therefore conforms to the latest international standards (IEC 60079-0/11/18/26/31/7).

The HF5-EX series consists of a robust aluminium transmitter with or without display. The attached probes are cast into a stainless steel tube, and are certified for operation in Zone 0/20. The transmitter itself is certified for Zone 1/21. “Compared to its predecessor, the new explosion-proof device no longer needs an intrinsically safe power supply thanks to a clever circuit design with galvanic isolation,” says Uolf Grass, Product Manager at Rotronic.

The HygroFlex5-EX advantages at a glance:

• Measurement of relative humidity and temperature, optional output of dew point and other calculated parameters

• Safe operation in areas with explosion risk

• Intrinsically safe electrical construction

• No intrinsically safe power supply required

• Interchangeable stainless steel probes

• Robust aluminium housing
