The SLAMf series of elastomer-sealed, IP66-rated thermal mass flow controllers (MFCs) now offer Class I/Division 2 and Zone 2 approvals for hazardous and harsh environments. These MFCs are also available with high-speed EtherNet/IP and Profinet communications protocols. They were designed with a NEMA4X/IP66 enclosure and hold relevant certifications including UL, ATEX, IECEx, KOSHA and CE. Key enhancements also include clamshell connectors for full UL compliance to ensure that cables do not disconnect unintentionally and risk a spark that could lead to an ignition event. The hazardous area-approved connectors and cabling also help reduce installation time and costs. In addition, an external diagnostic port provides access to device attributes and diagnostic settings during setup and for verifying calibration.
