Dust monitor
４．Mounting method
To mount Dust Monitor, 1 -socket is provided with.
Weld the socket onto the pipe. Install the dust monitor so it is horizontal or vertical.
Welding should execute all around the pipe to shut off gas.
4-1．Precaution for mounting
Dust Monitor may mal-function in an environment as listed hereunder.
Mounting Monitor in such environment should be refrained from, please.
(1) Plumbing pipe to be extremely squeezed or close to a place bending.
(2) Mounting position within diameter of duct or 1.5 of vertical dimension.
(3) Near a fan
(4) Fitting plumbing pipe・short pipe・duct are nonconductive.
(5) Measure environment and conditions are out of specification.
(6) In case raising bulk up with short pipe in a place where dusts accumulate between short
pipe and probe.
(7) Place where tip of probe is within 20mm from plumbing pipe.
Important : Wiring of power and signal should be independent, please.
Cap is for transport protection and is not a raincoat.
Attention :・Exclusive cable is transmitting very weak signal.
Cable should be protected with, by all means, steel made electric wire pipe
independently so that inductive noise form ambient area does not bother signal.
・Securely close the lead outlet to prevent outside air from entering in the main
unit.
Do not remove the accessory Silica gel. (for dehumidification)
・Where using conduit piping and so on instead of cable grand, be sure to apply
putty or like at cable entry so that ambient air does not come into the unit.
・Isolate the evaluation unit from the outer noise sources and take any measure
against noise if there may be any noise from power supply/signal lines.
