Your success counts Overview application E490 The E490 takes operating energy from an input current (2-wire 4 - 20mA), allowing easy installation in almost any 2-wire, 4-20mA loop. 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 displayed in their own engineering units. The E490 offers you a multi-purpose indicator designed to be used in rough and tough applications, beyond being just explosion proof. Its sturdy design and ease of use are...
