F074

Safe area / Intrinsically safe - Level / Pump Controller

with one control output

Product description

The F074 is a basic level indicator / pump controller that works with a preset value and two switch points to control a pump or valve. The low and high level switch points are entered as a percentage of the preset value to switch the device on / off. For pump control applications, the function can be inverted to empty a well. A stable level within a hysterese around the preset value is the result.

The configuration of the Span, off-set and number of decimals is done through software functions, without any sensitive DIP-switches or trimmers.

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.
