Thiết Bị Đo Mức Chất Lỏng Model FKE-5, EDSX7-66g

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 (vaccum limit);

Silicone fill sensor: See Fig.1

Fluorinated fill sensor: 66kPa abs (500mmHg abs) at temperature below 60°C.

-The maximum span of each sensor can be converted to different units using factors as below.

1MPa=10³kPa=10bar=10.19716kgf/cm²=145.0377psi

1kPa=10mbar=101.9716mmH2O=4.01463inH2O

Overrange limit: To maximum static pressure limit

Output signal: 4 to 20mA DC with digital signal superim-posed on the 4 to 20mA signal

Power supply: Transmitter operates on 10.5V to 45V DC at transmitter terminals.

10.5V to 32V DC for the units with optional arrester.

Hazardous locations: See TABLE 2

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 or local configurator unit with LCD display.

The time constant is adjustable between 0.06 to 32 seconds.

Zero elevation/suppression:

-100% to + 100% of URL

Normal/reverse action:

Indication: Selectable from HHC(1)

Analog indicator or 5-digit LCD meter, as specified.

Burnout direction: Selectable from HHC(1)

If self-diagnostic detect transmitter failure, the analog signal will be driven to either "Output Hold", "Output Overscale" or "Output Underscale" modes.

"Output Hold": Output signal is hold as the value just before failure happens.

"Output Overscale": Adjustable within the range 20.0mA to 22.5mA from HHC(1)

"Output Underscale": Adjustable within the range 3.2mA to 4.0mA from HHC(1)

Loop-check output: Transmitter can be configured to provide constant signal 3.2mA through 22.5mA by HHC(1).

Temperature limit:
 Ambient: −40 to + 85°C
  (−20 to + 80°C for LCD indicator)
  (−40 to + 60°C for arrester option)
  (−10 to + 60°C for fl  uorinated oil fi  ll transmitter)
  For explosionproof units (fl  ameproof or intrinsic safety),
ambient temperature must be within the limits speci-
fi  ed in each standard.

Storage: −40 to + 90°C

Humidity limit:  0 to 100% RH

Communication: With HHC(1)(Model FXW, consult Data Sheet No. EDS8-47), following items can be remotely displayed or configured.
      Note: HHC’s version must be higher than 7.0 (or FXW  1– 4), for FCX -AIII.
Local confi  gurator with LCD display (option):
     Local confi  gurator with 3 push button and LCD display can support following items

Programmable output linearization function:
    Output signal can be characterized with    
“14 points linear approximation function”
from HHC(1)
.
EMC Conformity: EN61326-1: 2006  Œ

ORDERING INFORMATION

When ordering this instrument, specify:
1. CODE SYMBOLS
2. Measuring range
3. Output orientation (burnout direction) when abnormality
is occurred in the transmitter.
 Hold / Overscale / Underscale.
 Unless otherwise specifi  ed, output hold function is sup-
plied.
4. Indication method (indicated value and unit) in case of
the actual scale (code D, H, P, S, 2, 5 on 9th digit).
5. TAG No. (up to 14 alphanumerical characters), if re-
quired.
