The E490 is a versatile, loop powered multi-purpose indicator to display the actual process value, range and loop current. Besides the focus on level, temperature and pressure applications, the E490 can also work with other measuring units, like %, mA, RPM and more.
The input circuit is separated from the backlight circuit and has an ultra low voltage drop < 1.5V DC. The measuring unit to be displayed is simply selected through an alfa-numerical configuration menu. The E490 accepts 4 - 20mA input signals from a wide range of process instruments, including flow (linear or square root), level, pressure and temperature transmitters. Making it the perfect fit for almost any explosion proof application where you want to display an analog process value.
Robust and weatherproof
The robust solid die cast aluminum and the stainless steel 316L E-Series housings are designed to guarantee safety. It takes the E490 Explosion Proof Multi-Purpose Indicator beyond the legal requirements for hazardous areas. In the harshest environmental conditions, as found in deserts and maritime climates with extreme temperature fluctuations, the durable E-Series consistently delivers accurate measurements.
The E490 is extremely practical in use. The touch-through-glass keypad allows for a safe and effortless operation of all functionalities without having to remove the glass cover. The menu, display and navigation structure are designed according to the Fluidwell “know one, know them all” principle, which enhances easy and intuitive control of various Fluidwell totalizers, flow computers and other displays.
