E490 Explosion Proof - Multi-Purpose Indicator

Your benefits

• Universal loop-powered indicator.
• Input signal: Galvanically isolated 4 - 20 mA with ultra-low voltage drop < 1.5 V DC, allowing easy installation in virtually any 2-wire 4-20 mA loop.
• LED backlight circuit that can be powered from the loop (voltage drop 6.5 V DC), separated from the input circuit.
• Create a custom measurement unit with up to 8 characters.
• Selectable engineering units for many different applications: L- NL-mL - M3- AM3- NM3 - mg - g - Kg - TON- OZ- GAL - USGAL - IGAL - lb - bbL- cf - CUFt - scf - p - rev - °C - °F - K - % - M - mm - CM - mtr - inch - Ft - SQFt - Yd - PSI - psig - mbar - MbARG - bar - barg - bara - PA - PAG - KPA - KPAG - MPA - INHG - mmHg - mmH2O - MH2O - INH2O- Ph - mV - mA - A - uS - PPM - RPM - custom unit or no unit.
• Saves time and improves flexibility with the touch-through-glass keyboard: no need to open the front cover
• Familiar, simple operation with the Fluidwell "Know one, know them all" configuration structure, saving time, cost and aggravation.
• Easy installation in spacious room and plug and play connectors.
• Durable high-quality 316L Ex d stainless steel housing that can withstand extreme marine conditions (optional).
• Important information at a glance as the display shows the actual value, unit of measure and loop current and a 10-segment bar graph.

Information about hazardous areas

The E490 is ATEX and IECEx certified for an ambient temperature range of -40°C to +70°C (-40°F to 158°F) for the aluminum housing. Ambient temperature stainless steel housing: -40°C to +67°C (-40°F to 153°F).

Robust indicator for a wide range of applications

The E490 is a versatile, loop-powered multifunction indicator to display actual process value, range and loop current. In addition to focusing on level, temperature and pressure applications, the E490 can also work with other measurement units, such as %, mA, RPM and even the ability to create a measurement unit with up to 8 characters.

The input circuit is separated from the backlight circuit and has an ultra-low voltage drop < 1.5 V DC, allowing easy installation in virtually any 2-wire, 4-20 mA loop. The unit of measure to be displayed is simply selected via an alphanumeric configuration menu. The E490 accepts 4 - 20 mA input signals from a wide range of process instruments, including flow (linear or square root), level, pressure and temperature transmitters. This makes it the perfect solution for virtually any explosion-proof application where you want to display an analog process value.
