Installation Guidelines
II. ELECTRONICS LOCATION CONSIDERATIONS
A remote electronics enclosure is required when ambient temperatures near the sensor exceed 65°C (149°F)
where the electronics will be mounted. The combination of several factors relative to temperature should be
considered when mounting the switch/transmitter:
A. High temperatures of the process material, which may over time, become a convective heat source.
B. High ambient temperature, which may prevent the surrounding air from cooling or insulating the
electronics.
C. Radiant heat, if the switch/transmitter is installed in direct sun in a hot climate, or near a heat source.
D. Mechanical features of the installation such as pipe insulation, heat sinks, cooling fans, etc.
