ProMinent DULCOMETER PH-501 Assembly And Operating Instructions Manual page 796

Noise level
Measuring-surface sound-pressure level as per
EN ISO 3744, measured at a distance of 1 m
[3.28 ft] at an operating point of approximately
2/3 of the permissible total pressure difference
with the lines connected without a vacuum or
pressure relief valve, tolerance ±3 dB (A).

Temperature increase
The information listed in the following tables
corresponds to the heating of vacuum
pump/compressor housings and the air exiting
compared to the ambient temperature during
operation with a permissible total pressure
difference and an air pressure of 1,013 mbar
[14.7 psi]. At lower air pressures these values
increase.
