10.1.8 Operating conditions: Environment
Ambient temperature range Transmitter:
• Standard: –20 to +60 °C (–4 to +140 °F)
• Optional: –40 to +60 °C (–40 to +140 °F)
!
Note!
At ambient temperatures below –20 °C (–4 °F), the readability of the display may be impaired.
Sensor:
• Flange material carbon steel: –10 to +60 °C (+14 to +140 °F)
• Flange material stainless steel: –40 to +60 °C (–40 to +140 °F)
"
Caution!
Do not exceed the min. and max. temperatures for the lining of the measuring tube
(→ "Medium temperature range").
Note the following points:
• Install the device at a shady location. Avoid direct sunlight, particularly in warm climatic regions.
• If both fluid and ambient temperatures are high, install the transmitter at a remote location from
the sensor (→ "Medium temperature range").
Storage temperature The storage temperature corresponds to the operating temperature range of the transmitter and
sensor.
"
Caution!
• The measuring device must be protected against direct sunlight during storage in order to avoid
unacceptably high surface temperatures.
• Choose a storage location where moisture does not collect in the measuring device. This will help
prevent fungus and bacteria infestation which can damage the lining.
Degree of protection • Standard: IP 67 (NEMA 4X) for transmitter and sensor
• Optional: IP 68 (NEMA 6P) for remote version of Promag W and Promag P sensors
Shock and vibration resistance Acceleration up to 2 g in accordance with IEC 600 68-2-6
(High-temperature version: no data available)
