ACCURACY—
Refer to the appropriate Appendix for details.
noTe
Misalignment will cause the manufacturer stated
Accuracy limits to increase, but remain within the
limits of en 50241‑1, ‑2, en 60079‑29‑4, and IeC
60079‑29‑4.
TEMPERATURE RANGE—
Operating: –55°C to +60°C (–67°F to +140°F)
Storage:
–55°C to +85°C (–67°F to +185°F)
Hazardous Locations: Refer to the appropriate
Appendix for correct ambient
temperature range:
Appendix A - FM
Appendix B - CSA
Appendix C - ATEX
Appendix D - IEC
HUMIDITY—
5 to 99% relative humidity; designed for outdoor
applications.
OPERATING PRESSURE—
91.5 - 105.5 kPA non-compensated.
MEASUREMENT RANGE—
0-5 LFL-meters.
INTERFERENCE RESISTANCE—
Immune to sun and flare radiation, tested to 800 ±50
W/m 2 ≥ 3° to optical axis and common contaminants.
SELF-DIAGNOSTIC TEST—
Fail-Safe operation ensured by performing all critical
tests once per second.
MODULE HOUSING MATERIAL—
316 stainless steel (CF8M).
CONDUIT ENTRY OPTIONS—
Two entries, 3/4 inch NPT or 25 mm.
HART COMMUNICATION PORT—
An intrinsically safe port is provided on the receiver for
connecting a Rosemount/Emerson HART Communicator.
• Maximum separation distance between receiver and
communicator is 610 meters.
OPTICS PROTECTION—
Stainless steel brow provides a degree of protection
against windblown dirt and rain. Heated optics mitigate
against ice and dew formation.
WIRING—
Field wiring screw terminals are UL/CSA rated for up to
14 AWG shielded wire, and are DIN/VDE rated for 2.5
mm 2 wire. Screw terminal required torque range is 3.5–
4.4 lb.-in. (0.4-0.5 N·m). Receiver can be wired using 3
or 4 wires. Transmitter requires two wires (power only).
