Thiết Bị Đo Mức Chất Lỏng Model FKY-5, EDSX7-67g
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: 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=103
kPa=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.
Load limitations: see fi gure below
Note: For communication with HHC(1) (Model: FXW), min. of 250Ω required.
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 confi gurator 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:
Selectable from HHC(1)
Indication: 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 confi gured to provide
constant signal 3.8mA through 22.5mA
by HHC(1).
.
Temperature limit:
Ambient: −15 to +65°C
(−15 to +65°C for LCD indicator)
(−15 to +60°C for arrester option)
(−10 to +60°C for fl uorinated oil fi ll transmitter)
(−10 to +60°C for silicon oil “H”, “S”)
For explosionproof units (fl ameproof or intrinsic safety),
ambient temperature must be within the limits speci-
fied in each standard.
Process:
Low pressure side contact liquid temperature on transmitter of Code H, S, is 120°C or lower.
Storage:−40 to +70°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 confi gured.
Note: HHC’s version must be higher than 7.0
(or FXW 1– 4), for FCX -AIII.
Local configurator with LCD display (option):
Local configurator 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
