Your success counts Overview application F490 The F-Series is your first and safest choice for field mount indicators in safe and hazardous area applications. Especially in harsh weather conditions like rain, snow, salty atmospheres and temperatures between -30°C up to +70°C (-22°F up to 158°F). The F490 takes operating energy from an input current (2-wire 4 - 20mA) and reduces installation cost. It accepts a wide range of process instruments, including flow (linear or square root), level, pressure and temperature transmitters. The proces values of all these types of instruments, can be...

Your success counts Enclosures Various types of enclosures can be selected, all ATEX, IECEx and CSA approved. The F490 is supplied in an GRP panel mount enclosure as standard, which can be converted to an IP67 / NEMA 4X GRP field mount enclosure by the addition of a back case. Most popular is our robust aluminum field mount enclosure which is so rugged, even a truck can stand on it! This is also available with an extended backcover with undrilled preparation for direct meter mounting at the back side. For the most challenging environments, we have a durable high grade Stainless steel 316L...
