The HP140-IS Duct-Mount RH Transmitter and the HP150-IS Wall-Mount Transmitter have been designed specifically for use in hazardous areas. The
interface between the hazardous and safe areas must be via intrinsic safety zener diode barrier. They operate as two-wire transmitters, generating a 4 to 20mADC signal that is linear and
proportional to 0% to 100%RH. The transmitters carry Intrinsic Safety Approval by BASEEFA for use in Zone 0 conditions and certified to EEXia IIC T4 under Certificate Number EX85B2195.
