Model LF410 and LF414 Detectors
Mounting style: Wafer type
Fluid pressure:
-
0.1 to 2.0MPa
(
-
15 to 300psi, or
-
1.0 to 20 bar)
Note: The test pressure before shipping from the factory
is equal to twice the nominal pressure rating of the
customer specified flange connection during 15
minutes.
Connection flange standards: ANSI 150, ANSI
300, BS10 and 16, DIN PN10 and PN16, JIS10K,
JIS16K and JIS20K
Principal materials:
Case — 25 to 100mm (1” to 4”): stainless steel 15,
150, and 200mm (1/2”, 6”, and 8”): carbon
steel
Linings — 15 to 100mm (1/2” to 4”): Ceramic
tube (std.) & teflon PFA (opt.)
150 and 200mm (6” to 8”): teflon PFA
Electrodes — 316L stainless steel (std.)
Grounding rings — 316 stainless steel (std.)
Note: See Table 3 for optional materials and other
related information.
Measuring tube material 304 stainless steel
(in case of Teflon PFA lining)
Coating — 25 to 100mm (1” to 4”): no coating
(stainless steel body).
15, 150, and 200mm (1/2”, 6”, and 8”):
phthalic acid resin coating with pearl-gray
colored.
Heat shock resistance : for a ceramic tube detector
Heating: ΔT 150
°C/0.5sec (302°F/0.5sec)
Cooling: ΔT 100
°C/0.5sec (212°F/0.5sec)
Note: The above means that the ceramic tube detector
withstands the shock of sudden heating
(temperature difference 150°C or less per
0.5seconds) and sudden cooling (temperature
difference 100°C or less per 0.5seconds).
Dimensions and weights: See Figures 3 to 8.
Cable connection port: for separate type detectors.
Cable glands
LF410: without cFMus approval
Provided as standard
R(PT) 1/2 male screws.
LF414: with cFMus approval
Not provided
3/4-14NPT male screws are required.
Applicable diameter — 11 to 13mm
(0.433 to 0.512 inch)
Model LF600 and LF602 converters
Input signals
Analog signal the voltage signal from detector,
proportional to process flow rate (for LF602
separate type converter).
Digital input DI (opt.)
Signal type: 20 to 30Vdc voltage signal
Input resistance: 2.7kΩ
Number of inputs: one point
DI function — One of the following functions can
be assigned to the optional DI signal.
Range switching — Selects either the higher or
lower range in the unidirectional or
bidirectional 2-range setting.
