Fluidwell E490P | Explosion proof Multi-Purpose Indicator (pressure version) | Loop Powered, for universal applications, ambient -40°C to +70°C
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 even the possibility to create a custom unit with max. 8 characters. The measuring unit to be displayed is simply selected through an alfa-numerical configuration menu. Typical use: Universal applications when a local loop-powered multi-purpose display is required without monitoring function, linearization or signal re-transmitting.
Key features
- Explosion proof according ATEX, IECEx and CSA C-US.
- Universal loop powered indicator.
- Input signal: Galvanically isolated 4 - 20mA with ultra low voltage drop < 1.5V DC, allowing easy installation in almost any 2-wire, 4–20mA loop.
- Create a custom measuring unit with max. 8 characters.
- Aluminum or high grade stainless steel Ex d enclosure.
- Easy installation with the spacious chamber and plug & play connectors.
- Key information at a glance as the display shows the actual value, measuring unit and loop current and a 10 segments bargraph.

| Part Number | E490P |
| Brand | Fluidwell |
| Product Type | Multi-Purpose Indicator |
| Enclosure / Area | Explosion proof |
| Ambient Temperature | -40°C to +70°C |
| Signal Inputs - Multi Purpose Inputs | Galvanically isolated 4 – 20mA input loop-powered with ultra low voltage drop < 1.5V DC. |
| Supply - Power Supply | 4 – 20mA, input Loop-powered, the loop can power the backlight.; The E490 can also be powered 9 - 27V DC externally, then the backlight lights up at full intensity and it will not influence the voltage drop in the loop. |

Dust: Ex tb IIIC T85°C Db.; CSA C-US: XP (Explosion-proof): Class I, Division 1, Groups A, B, C, D. DIP (Dust-Ignition-proof): Class II, Div. 1, Groups E, F, & G T85°C; Class III. Gas: Class I, Zone 1, AEx db IIC T6 Gb. Dust: Zone 21, AEx tb IIIC T85°C Db. |
| Communication | HART communication is available with the E018 Flow rate Monitor / Totalizer. |
- In accordance with ATEX and IECEx, explosion proof.
- An indicator powered by a universal loop.
- Galvanically isolated 4–20 mA input signal with an extremely low voltage drop of less than 1.5 V DC makes installation simple in practically any 2-wire, 4–20 mA loop.
- Make a unique measuring unit using no more than eight characters.
- Ex terior enclosure made of premium stainless steel or aluminum.
- Plug and play connectors and a roomy chamber make installation simple.
- The display provides important details quickly, including the loop current, actual value, measurement unit, and a 10-segment bargraph.
- Five big 17.3mm (0.7") digits.
- The LED backlight circuit is independent of the input circuit and can be powered from the loop (voltage drop of 6.5V DC).
- automatic backup of every configuration.
- Aluminum enclosure ambient temperature range: -40°C to +70°C (-40°F to 158°F).
