2.2 Selecting the Installation
Location
Thetransmitterisdesignedtowithstandsevere
environmentalconditions.However,toensurestable
andaccurateoperationforyears,observethefollowing
precautionswhenselectinganinstallationlocation.
(a)AmbientTemperature
Avoidlocationssubjecttowidetemperaturevariations
orasignicanttemperaturegradient.Ifthelocation
isexposedtoradiantheatfromplantequipments,
provideadequatethermalinsulationand/or
ventilation.

<2. Handling Cautions> 6
IM 01C22A01-01E
(b)AmbientAtmosphere
 Avoidinstallingthetransmitterinacorrosive
atmosphere.Ifthetransmittermustbeinstalledin
acorrosiveatmosphere,theremustbeadequate
ventilationaswellasmeasurestopreventintrusionor
stagnationofrainwaterinconduits.
(c)ShockandVibration
 Selectaninstallationsitesufferingminimumshock
andvibration(althoughthetransmitterisdesignedto
berelativelyresistanttoshockandvibration).
(d) Installation of Explosion-protected Transmitters
 Explosion-protectedtransmitterscanbeinstalled
inhazardousareasaccordingtothetypesof
gasesforwhichtheyarecertied.SeeSubsection
2.4 “Installation of Explosion Protected Type
Transmitters.”
2.3 Pressure Connection
WARNING
• Instrumentinstalledintheprocessisunder
pressure.Neverloosentheprocessconnector
boltstoavoidthedangerousspoutingofprocess
uid.
• Duringdrainingcondensatefromthepressure
detectorsection,takeappropriatecaretoavoid
contactwiththeskin,eyesorbody,orinhalation
ofvapors,iftheaccumulatedprocessuidmaybe
toxicorotherwiseharmful.
Thefollowingprecautionsmustbeobservedinorderto
safelyoperatethetransmitterunderpressure.
(a)Makesurethattheprocessconnectorboltsare
tightenedrmly.
(b)Makesurethattherearenoleaksintheimpulse
piping.
(c) Neverapplyapressurehigherthanthespecied
maximumworkingpressure.
CAUTION
MaximumworkingpressureofthemodelEJA120A
differentialpressuretransmitteris50kPa
{0.5kgf/cm2}.
Shouldthepressureexceed50kPa{0.5kgf/cm2}, it
ispossibletobreakthesensor.Proceedwithcaution
whenapplyingpressure.
2.4 Installation of Explosion

non-observanceornegligenceofthisrestrictionwould
result in dangerous condition.
WARNING
Topreservethesafetyofexplosionproofequipment
requiresgreatcareduringmounting,wiring,and
