Endress+Hauser Gammapilot FMG50 - Environment; Ambient Temperature; Climate Class; Operating Altitude as Per IEC 61010-1 Edition 3.1

Gammapilot FMG50
32 Endress+Hauser
Measurement of mass flow (solids)
Bulk solids applications on conveyor belts and conveyor screws.
The source container is positioned above the conveyor belt and the Gammapilot FMG50 below the
conveyor belt. The radiation is attenuated by the medium on the conveyor belt. The intensity of the
radiation received is proportional to the density of the medium. The mass flow is calculated from the
belt speed and the radiation intensity.

Environment
Ambient temperature
NaI (Tl) crystal
Ambient temperature:–40 to +80 °C (–40 to +176 °F)
PVT scintillator (standard)
Ambient temperature:–40 to +60 °C (–40 to +140 °F)
PVT scintillator (high-temperature version)
Ambient temperature:–20 to +80 °C (–4 to +176 °F)
The temperature range may be restricted for applications in hazardous areas. Observe the
maximum ambient temperature indicated in the relevant approval. Avoid exposure to direct
sunlight; use a weather protection cover.
Storage temperature
NaI (Tl) crystal
–40 to +80 °C (–40 to +176 °F)
PVT scintillator (standard)
–40 to +60 °C (–40 to +140 °F)
PVT scintillator (high-temperature version)
–20 to +80 °C (–4 to +176 °F)
As the device contains a battery, it is recommended to store the device at room temperature in
a location that does not receive direct sunshine
Climate class
IEC 60068-2-38 Test Z/AD
Operating altitude as per IEC
61010-1 Edition 3.1
5 000 m (16 404 ft)
Degree of protection
• When housing is closed:
• IP68 (at 1.83 m under water), NEMA Type 6P
• IP66, NEMA Type 4X
• When housing is open: IP20, NEMA Type 1
With the M12 connector, the IP68 NEMA Type 6P degree of protection only applies if the
connecting cable is plugged in and is also specified to IP68 NEMA Type 6P.
The following applies if a HAN7D connector is used:
• When housing is closed and connecting cable is plugged in: IP65, NEMA Type 2
• When housing is open and/or connecting cable is not plugged in: IP20, NEMA type 1
