Transmitter –40 to +60 °C (–40 to +140 °F)
Sensor • Flange and threaded connection made of stainless steel:
–40 to +60 °C (–40 to +140 °F)
• Flange connection PN16 made of carbon steel:
–10 to +60 °C (–14 to +140 °F)
• Flange connection Cl.150 made of carbon steel:
–29 to +60 °C (–20.2 to +140 °F)
Local display –20 to +60 °C (–4 to +140 °F)
The readability of the display may be impaired at temperatures outside the temperature range.
‣
If operating outdoors:
Avoid direct sunlight, particularly in warm climatic regions.
System pressure
Sensor
Depending on the version, please note the details on the name plate .
Max. 40 bar g (580 psi g)
Thermal insulation
If the gas is very humid or saturated with water, the pipe and the sensor housing should be
insulated to prevent water droplets condensing on the transducer.
NOTICE
Electronics overheating on account of thermal insulation!
‣
Observe maximum permitted insulation height of the transmitter neck so that the
transmitter head is completely free.
