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.
