F040 Safe area / Intrinsically safe – Temperature Indicator
The F040 is a straight forward temperature indicator with large 26mm (1″) high digits. The measuring unit to be displayed below the temperature is simply selected through an alphanumeric configuration menu.
Measure. Monitor. Repeat.
For better insights, better decision-making and better process performance.
Key Features & Benefits
- Displays actual temperature and measuring unit.
- Very large 26mm (1″) high digits for temperature.
- Selectable on-screen engineering units:
°C – °F – K. - Number of digits for temperature: 5½.
- Piegraph indication: ten segments.
- LED backlight with adjustable intensity.
- Intrinsically safe according ATEX, IECEx and CSA C-US.
- GRP, Aluminum or high grade stainless steel enclosure.
- Auto backup of settings in EEPROM memory.
- Easy configuration with clear alphanumerical display.
- Ambient temperature: -40°C to +70°C (-40°F to 158°F).
Typical Applications
- Applications where a basic temperature measurement display is required without temperature monitoring or signal re-transmission.
- The F-Series is your first and best choice for field mount indicators in safe and hazardous area applications. Especially in harsh weather conditions like rain, snow, sandy deserts, salty atmospheres and temperatures between -40°C up to +70°C (-40°F up to 158°F).
Advantages
- Robust aluminum or stainless steel 316L field enclosure (IP65, IP67 / NEMA Type4X) .
It is so rugged, a truck can even stand on it! - Intrinsically Safe available - ATEX, IECEx and CSA approval for gas and dust applications.
- Familiar easy operation with the Fluidwell "Know one, know them all" configuration structure, saving time, cost and aggravation.
- Very diverse mounting possibilities: walls, pipes, panels or directly onto outdoor sensors.
