2.2 Selecting the Installation

Location

Thetransmitterisdesignedtowithstandsevere

environmentalconditions.However,toensurethatitwill

provideyearsofstableandaccurateperformance,take

thefollowingprecautionswhenselectingthe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equipment,provide

adequatethermalinsulationand/orventilation.

(b)AmbientAtmosphere

 Donotinstallthetransmitterinacorrosive

atmosphere.Ifthiscannotbeavoided,theremustbe

adequate ventilation as well as measures to prevent

theleakingofrainwaterandthepresenceofstanding

waterintheconduits.

(c)ShockandVibration

 Althoughthetransmitterisdesignedtoberelatively

resistanttoshockandvibration,aninstallationsite

shouldbeselectedwherethisiskepttoaminimum.

(d)InstallationofExplosion-protectedTransmitters
