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.
