Housings
The stainless steel housing of Cerabar M
is especially remarkable due to its
chemical resistance and hygienic
properties. Having no dead volume and
being condensation-tight with a surface
roughness of Ra
≤
0,8
µ
m, it is easy to
clean and thereby ideal for the food and
pharmaceutical industry.
The aluminium housing has proven its
ruggedness and has become a
standard in many industries such as
chemicals, papermaking, power
generation, water and wastewater
treatment.
•
Ingress protection

assembled cable with pressure
compensation or plug M 12x1.
This version is recommended for
very moist applications (e.g. wet
vessel walls or pipes).

−
cable gland M 20x1.5 or
−
cable entry ½ NPT or G ½,
−
Harting plug (Han7D) or

a local display.
Electronic Inserts
Cerabar M has three electronics versions
•
Analogue: 4…20 mA
Operation directly at the measuring
point with one potentiometer each for
lower range-value and upper
range-value and a three-step range
switch as well as an on/off switch for
damping.
•
Smart: 4…20 mA with HART protocol
Operation:
−
at the measuring point via two push
buttons for lower range-value and
upper range-value as well as an
on/off switch for damping, or
−
via the Universal HART Communicator
DXR 275 handheld terminal at any
point along the 4…20 mA line, or
−
via PC e.g. with the Hauser
Commuwin II operating program.
•
PROFIBUS-PA:
Operation:
– Using a PC with an operating
program, e.g. Commuwin II from
Hauser, or
– using two keys for lower range-value
and upper range-value.
