GEORGIN FKE Level transmitter

Description of GEORGIN FKE

The ProcessX level transmitter accurately measures liquid level and transmits a proportional 4 to 20 mA signal.
The transmitter utilizes a unique micromachined capacitance silicon sensor with state-of-the-art microprocessor technology to provide exceptional performance and functionality.

FEATURES

High accuracy:
0.165% accuracy for all calibrated spans is a standard feature. The micro-capacitance silicon sensor assures this accuracy for all elevated or suppressed calibration ranges without additional adjustment. 0.1% accuracy is available as option.

Minimum inventory and design:
Electronics unit, local indicators and electronics housing are interchageable among all ProcessX transmitters.

Minimum environmental influence:
The “Advanced Floating Cell” design which protects the pressure sensor against changes in temperature, static pressure, and overpressure substantially reduces total measurement error in actual field applications.

Georgin/HART® bilingual communications protocol:
ProcessX series transmitter offers bilingual communications to speak both Georgin proprietary protocol and HART®. Any HART® compatible devices can communicate with ProcessX.

Application flexibility:
Various options that render the ProcessX suitable for almost any process applications include :

• Full range of hazardous area approvals,
• Built-in RFI filter and lightning arrester,
• 5-digit LCD meter with engineering unit,
• Stainless steel electronics housing,
• Wide selection of materials.

Programmable output Linearization Function:
Output signal can be freely programmable. (Up to 14 compensated points at approximation).

Burnout current flexibility (Under Scale: 3.2 to 4.0 mA, Over Scale: 20.0 to 22.5 mA):
Burnout signal level is adjustable using Model FXW or Hand Held Communicator (HHC) to comply with NAMUR NE43.

Dry calibration without reference pressure:
Thanks to the best combination of unique construction of mechanical parts (Sensor unit) and high performance electronics circuit (Electronics unit), reliability of dry calibration without reference pressure is at equal level as wet calibration.
