MD201 MB
a pressure gauge and a pressure switch
and is therefore suited to control pressure
differentials of filters used in cleanroom
and climate technology. The MD201 MB
instruments feature a high reading ac-
curacy and repeatability. They can be
used in negative pressure and/or over-
pressure conditions. This is essential

The well-proven MD201 MB combines
for air halls or research/experimental
laboratories which for safety reasons
need to be kept above or below at-
mospheric pressure level. Differential
pressure gauge and switch are as-
sembled in a bi-partite, weather-proof
and shock-resistant plastic housing
and are ready for connection. The de-
vice needs almost no maintenance,

as it works without any manometer fluids.
After opening the housing, the switching
point can be set at each individual dif-
ferential pressure switch (alternatively for
rising or falling pressure) by means of the
adjusting knob with scale. Due to its high
reading accuracy, the integrated differen-
tial pressure gauge can also be used for
pre-setting the switching point.
