FKE-5 Level transmitter ■ DATA SHEET 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 1. 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. 2. Minimum inventory and design Electronics unit, local indicators and electronics housing are interchageable among all ProcessX transmitters. 3. 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. 4. 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. 5. 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. 6. Programmable output Linearization Function Output signal can be freely programmable. (Up to 14 compensated points at approximation). 7. 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. 8. 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. Functional specifications Type : FKE : Smart, 4-20 mA DC + Georgin/Hart® digital signal Service : Liquid, gas or vapour Static pressure, span, and range limit : Remark : To minimize environmental influence, span should be greater than 1/40 of the max. span in most applications. Lower limit of static pressure (vacuum limit) : Silicone fill sensor : See Fig.1 Fluorinated fill sensor : 66 kPa abs (500 mmHg abs) at temperature below 60 °C. See fig.2 Overrange limit : To maximum static pressure limit. Output signal : 4 to 20 mA DC with digital signal superimposed on the analogic signal. Power supply : Transmitter operates on 10.5 V to 45 V DC at transmitter terminals. 10.5 V to 32 V DC for the units with optional arrester. FC-FKE-EN-24-07-2017 Subject to modification due to technical advances

Note : For communication with HHC(1), min. of 250 0 required. Hazardous locations : See below Refer to the package insert for safe use.

FKE-5 Level transmitter Zero/span adjustment : Zero and span are adjustable from the HHC(1). Zero and span are also adjustable externally from the adjustment screw. Damping : Adjustable from HHC(1) or local adjustment unit with LCD display. The time constant is adjustable between 0.12 to 32 sec. Zero elevation/suppression : -100% to + 100% of URL. Normal/reverse action : Selectable from HHC(1) Indication : Analog indicator or 5-digit LCD meter. Burnout direction : Selectable from HHC(1) If self-diagnostic detect transmitter failure, the analog signal will be driven to either "Output Hold", "Output...

Response time : (At 63,3% of output signal without damping) Note : Gasket : Viton O-ring or PTFE/15% graphite square section gasket. Temperature effect : Effects per 28°C change between the limits of -40°C and +85°C Zero shift (transmitter only) : ±0,3 of URL Zero shift (level kit only) : +0,3 mbar/28°C Total effect (level kit and transmitter : ± 0,3% of URL Note : The indicated values are for temperature compensation made on transmitter only, without level kit. Zero shift is improved (2 to 3 times) by an additional temperature compensation of the complete level transmitter (level kit and transmitter)....

Level transmitter Degreasing : Process-wetted parts are cleaned, but the fill fluid is standard silicone oil. Not for use on oxygen or chlorine measurement. Optional tag plate : An extra stainless steel tag with customer tag data is wired to the transmitter. Vacuum service : Special silicone oil and filling procedure are applied. See Fig.1 and Fig.2 below. NACE specification : Metallic materials for all pressure bound ary parts comply with NACE MR 0175/ISO 15156. SS 660 bolts and nuts comply with NACE MR 0175/ISO 15156.
