Fuji Electric VG Series FKE Level Transmitter

The Fuji Electric VG Series FKE level transmitter accurately measures liquid levels and transmits a proportional 4-20 mA output signal. The transmitter uses a unique micro-capacitive silicon sensor and state-of-the-art digital signal processing to provide exceptional accuracy and stability. The transmitter's silicon sensor assures this accuracy for all elevated or suppressed calibration ranges without additional adjustment.  The FKE offers a sampling period of 40 ms and a response time of 80 ms.

The FKE transmitter incorporates specific hardware and software features to comply with Safety Integrity Levels (SIL) 2 and 3 according to IEC 61508 and 61511 standards. The transmitters have a safety failure rate of 97%.

The FKE transmitter's advanced floating cell technology protects against temperature variations, static pressure and overpressure commonly found in the process industry, and substantially reduces the overall measurement error. The burnout current value can be adjusted in the ranges of 3.2 to 4 and 20 to 22.5 mA, and can be compliant with NAMUR NE43 recommendations. The transmitter's output signal can be linearized using up to 14 points.

The electronics unit, local indicators and electronics housing are interchangeable among all VG series transmitters. The VG series transmitters can also communicate using either the universal HART protocol or the proprietary, faster Fuji Electric communication protocol. Various options are available to address a wide range of process industry applications, including a full range of hazardous area approvals, a built-in RFI filter and lightning arrester, analog or 5-digit local display with engineering units, stainless steel electronics housing, and a wide selection of wetted part materials.
