Model LF410 and LF414 Detectors
Mounting style: Wafer type
Fluid pressure:
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
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

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
